treatment with benzyladenine (BA). Jpn. Number of QTLs detected in each trait ranged from 1 to 5 with an average of only 2.3. Pubescence of epicotyl, stem, leaf margins and pod, and the colour of the mature pod, characteristics of the black gram × green gram derivative, were also expressed in the hybrid. We studied pollination in Aloe peglerae, a high altitude, Pollen of a Sugi clone, Kumotoosi, Cryptomeria japonica, irradiated with gamma rays from a cobalt-60 source acutely or chronically was pollinated to non-irradiated female strobili of Kuma-sugi at the Institute of Radiation Breeding in 1965. 6, 59Ð60. When Bill and Geri Hanson purchased their farm northeast of Centerville, Iowa, in 1974, they were interested in growing black walnuts. The sterility or partial fertility of F 1 plants can be attributed to inter-genomic interactions or due to the presence of some lethal genes that were activated in interspecific hybrids. A true-breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis. Pod-set and percentages of pods harvested varied with the combinations of two parental cultivars of each species for most of the interspecific hybrid crosses. These studies and some other studies (Singh and Bains 2006) indicated that stable and high degree of resistance to MYMV and some other desirable traits could also be successfully incorporated into black gram from ricebean. A true-breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis. A true‐breeding black gram (Vigna mungo) × green gram (Vigna radiata) derivative was reciprocally crossed with adzuki bean, Vigna angularis. The reduced fertility has been ascribed due to pairing abnormality and the formation of the anaphase bridges and laggards leading to the unequal distribution of the chromosome by various workers (De & Krishnan, 1967;Biswas & Dana, 1975;Anandabaskaran & Rangasamy, 1996;Kaur & Satija, 1998; Interspeci®c hybridization in the genus Phaseolus Interspeci®c hybridization of food legumes by conventional methods of plant breeding Interspeci®c crossability among four species of Vigna food legumes. The study of this hybrid and four offspring revealed that green epicotyl colour of adzuki bean, and the pubescence of stem and leaf margins of the black gram × green gram derivatives were dominantly inherited traits. Seed productivity was also low on the intraspecific pollination of A. auriculiformis. Analysis of incompatibility barriers during cross-pollinations among Phaseolus L. and other leguminous plants, Distant hybridization and alien gene introgression, A Homoploid Hybrid Between Wild Vigna Species Found in a Limestone Karst, Introgression of productivity and other desirable traits from ricebean (Vigna umbellata) into black gram (Vigna mungo), Distant hybridization and alien gene introgression. Black gram : Country: India : Description: The mutant variety Co 4 was officialy approved in 1978. Overall, it was found that desirable traits such as high pod number, seed weight, productivity and resistance to diseases have been introgressed successfully into black gram from ricebean. 1st Int. Key words : Black gram, EMS, gamma rays, germination, survival, pollen sterility. Self-pollination occurs so insect and wind are not required. ANTHESIS AND POLLINATION • Pollination occurs a night prior to opening of the flowers • Anthers start dehiscing from 9 a.m and completely dehisced by 3 a.m • Stigma are by then receptive and are thoroughly covered with pollen • Flowers open between 6 a.m and 8 a.m and remain open till 11 a.m later they close between 2 p.m and 4 p.m 14. To force flowering, gibberellin solution of 200 ppm was sprayed on trees in July 1964. 103, 3Ð6. The genus Vigna comprises more than 200 species of which 7 are of tremendous agronomic importance. The relevance of these results for the development of plant tests for … 1) Autogamy or self pollination and 2) Allogamy or cross pollination. Seeds are 2.5–4 mm × 2.5–3 mm × 2.5–3 mm, globose to ellipsoid or cube-like. Black Gram (Vigna mungo) (Diploid, 2n = 22 & 24) Family – Fabaceae Self pollination is the rule. This chapter outlines the sources of resistance available for major insect pests of mung bean and urd bean, mechanisms of resistance, breeding methods for evaluation of genetic resources, alien gene introgression, genetic transformation and prospects in breeding for insect resistance in mung bean and urd bean. ), vegetables, fruits, and other crops of economic significance. Unisexuality and dioecism occur commonly although complete flowers have been observed occasionally. 2007). Seed germination was highest with blue, red by violet and white and poor with pink. Grams are annual legume crops grown for their seed. Poor crossability and partial fertility was also observed earlier by various workers in interspecific crosses involving Vigna species (Dar et al. (1979) P. vulgaris × P. lunatus Leonard et al. Complete hybrid sterility was found in the interspecific crosses of V. radiata x V. umbellata, V. radiata x V. angularis and V. mungo x V. angularis; while reduced fertility was observed for the interspecific hybrids of V. radiata x V. mungo, V. umbellata x V. angularis and V. angularis x V. umbellata. (1997) Cicer arietinum × C. reticulatum Ladizinsky and Adler (1976a, b) C. arietinum × C. echinospermum Pundir and Mengesha (1995) C. arietinum × C. pinnatifidum Mallikarjuna (1999) C. arietinum × C.bijugum Clarke et al. © 2013 International Formulae Group. . All rights are reserved. Cameo™ Red Cameo™ Golden Delicious MAIA11 Cltv. Chloroplasts became a little round in shape due to application of electric field. Pollination often occurs within Those fruits listed as self-fertile will set fruit with their own pollen. abiotic stresses have restricted potential expansion of black gram in new niches (Kumar et al., 2004). Key words : Black gram, EMS, gamma rays, germination, survival, pollen sterility. The interval between pollination and opening of flower is 4 hours. The difference in reproductive output between insect visited and visitor excluded flowers was not significant and suggests possible self-pollination in A. peglerae which is particularly unusual in Aloe species. In vitro pollination of isolated ovules of Cichorium intybus L. Phenological behaviour of selected tree species in tropical forests at Kodayar in the Western Ghats,... Gamma ray induced in vitro mutations in flower colour in Grandanthema grandiflora Tzelev, GERMINATION CHANGES OF VARIETIES OF VIGNA MUNGO L. UNDER TANNERY EFFLUENT STRESS, Comparative study of reciprocal crossing for establishment of acacia hybrids. 3) Study of floral structure of self pollinated crops. When pollination and fertilization occur in unopened flower bud, it is known as cleistogamy. It has a well-developed taproot and its stems are diffusely branched from the base. Purple tephrosia seeds take longer time as their seed coat is very hard. Pulse crops (Red gram, Black gram and Green gram) are basically self-pollinated in nature and don’t need any external pollination practices. Category. 65, 330Ð339. The best stage to harvest pearl millet is when the plants reach physiological maturity determined by the black spot at the bottom of the grain in the hilar region. Duration (days) Grain yield (kg/ha) Special features. results were explained in terms of pollen viability, pollen germination on the ovule, Vegetative and reproductive phenology of 42 tree species of tropical forests at Kodayar in the Western Ghats, Tamil Nadu, India was monitored through fortnightly visits for two years. Although seed productivity was not different between reciprocal crossings, number of mature seeds, seed germination percentage and number of seedlings acquired were significantly higher when A. mangium was used as the female adult and also varied greatly among cross combinations. OPV* Hybrids. Chen, N. C., J. F. Parrot, T. Jacobs, L. R. Baker, and P. S. Corison, 1977: Interspeci®c hybridization of food legumes by conventional methods of plant breeding. Inheritance of protruded stigma in black gram [Vigna mungo (L.) Hepper] was investigated in the F₁, F₂, and F₃ generations of four crosses and their reciprocals involving a natural flower mutant with its parent genotype (IPU 99-167) and three other genotypes (PLU 710, Type 9, and Barabanki local). endemic succulent of the Magaliesberg mountain range, previously thought to be largely sunbird (specialist) pollinated. Most of the distorted markers were clustered together and all the markers on LG8 were highly distorted markers. Seed viability and germination were low and variable; however, ~19 % seedling emergence was observed across the treatments. 2007). (1987) Growth regulators V. radiata × V. umbellata, ... Harlan and de Wet (1971) P. vulgaris × P. acutifolius Cabral and Crocomo (1989), Andrade-Aguilar and Jackson (1988) Lens culinaris × L. orientalis Ladizinsky et al. Copyright © 2003 Whurr Publishers Ltd, Flowers of cv Early Amber peach, a genotype which is homozygous recessive for green v. red leaf, yellow v. white fruit flesh and eglandular v. reniform glandular leaf, were hand-pollinated with a genetically different parent for three consecutive days. The hybrid was morphologically similar to V. umbellata but habituated in a limestone rock mountain, which is usually dominated by V. exilis. The breeding process normally comprises of these essential stages: 1) pollination and seedpod maturation, 2) in vitro seed germination, protocorms development and growth of seedlings, 3) ex vitro establishment of seedlings and growing seedlings to maturity, and 4) assessment of flower characteristics and quality (Hee et al. pods are variable in color (yellowish-brown to black), about five inches long, and contain 10 to 15 seeds. Use the link below to share a full-text version of this article with your friends and colleagues. It refers to unisexual flowers. The pollen germination, Access scientific knowledge from anywhere. Classification of crop plants based on mode of pollination and mode of reproduction Mode of pollination and reproduction Examples of crop plants A. Autogamous Species 1. Day 4…” Socio-economic status of the farmers has improved due to generation of additional income through seed production as compared to general cultivation. The present investigated the different concentrations of tannery effluent on seed germination and seedling growth of five variety of blackgram (Vigna, Using two Acacia mangium and five A. auriculiformis clones, Acacia hybrids were reciprocally artificially pollinated by tube pollination to determine which cross combination was more appropriate. As the black gram seed coat is not hard, it germinates earlier. One fertile pod containing two hybrid seeds was obtained, when V. angularis was used as the male parent. It ensures self pollination and prevents cross pollination. Five QTLs for tuber width and three QTLs for tuber weight. Enter your email address below and we will send you your username, If the address matches an existing account you will receive an email with instructions to retrieve your username, I have read and accept the Wiley Online Library Terms and Conditions of Use. of inspections to be conducted. usually not more than five viable seeds are produced on one plant. Vegetable crops – Bitter gourd (), Bottle Gourd, Brinjal, Chili, Ladyfingers, Sponge Gourd, Tinda, Tomato, Turmeric, and French Beans.. Rabi crops. The application of growth regulators to pistils for delaying the initiation of abscission of pods is usual for numerous interspecific hybridizations. (1984), L. orientalis × L. odemensis Ladizinsky et al. All the progenies were found resistant to Mungbean yellow mosaic virus, Cercospora leaf spot and Bacterial leaf spot diseases. The results low concentration 10% of tannery waste water promoted the germination, percentage growth, fresh, dry weight of blackgram seedlings, whereas the higher concentration (above 20%) reduced the above all the parameters. The prominent crops and their insect pests are compiled in Table 1.This list has the insects that regularly damage crops grown in Indian agricultural farms such as cereals (rice, wheat, maize, sorghum, etc. It belongs to the family leguminosae and subfamily papilionaceae. Large-effect QTLs (PVE > 20%) were on LG4 (pod length), LG5 (leaf size and seed thickness), and LG7 (for seed-related traits). In general, a cross using a species with higher chromosome number as a female parent is more successful than its reciprocal. 499-501 ISSN 0972-5210 Introduction Black gram [Vigna mungo (L.) Hepper] is an important pulse crop of our country. One fertile pod containing two hybrid seeds was obtained, when V. angularis was used as the male parent. (i) open to all visitors, (ii) bird excluded, and (iii) all visitors excluded, we established that birds contributed significantly more to fruit (2.3–5.6 times) and seed (1.3–1.4 times) set than insect or self-pollination, respectively. A linkage map with 11 linkage groups was constructed from this F2 population using 145 SSR, 117 RAD-seq and 2 morphological markers. Among the pollination sequences, day 2 (the day after emasculation) contributed a greater percentage progeny (45%) than day 1 (35%) or 3 (20%). 24 and 48 h after pollination. Such situation is found in tomato and brinjal. The flower opens in the morning at 7 am. Pollen grain viability appears to be low. Euphytica 32, 925Ð937. The original floral colour of 'Snow Ball' is white with flat and incurving florets. In acute irradiation, LD100 for seed germination was estimated to be 7 × 10³ and exposure that will result 50 per cent reduction of germination was 3~4 × l0³. 499-501 ISSN 0972-5210 Introduction Black gram [Vigna mungo (L.) Hepper] is an important pulse crop of our country. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant 80 days — 'Black Beauty' is the classic, garden standard for eggplants and commonly seen at farmer's markets and on produce stands. A legume (/ ˈ l ɛ ɡ j uː m, l ə ˈ ɡ j uː m /) is a plant in the family Fabaceae (or Leguminosae), or the fruit or seed of such a plant. Alien Gene Transfer in Crop Plants, Volume 2. All rights reserved. Centre, Shanhua, 247Ð252. In addition, the hybrid exhibited two novel traits — the presence of racemose inflorescence and plant regeneration ability — not present in the parents. Chickpea (gram) can be grown as one crop or combine with barely, linseed, mustard, peas, corn, coffee, safflower, potato, sweet potato, wheat or sorghum etc. Red and orange gave significantly greater growth of seedlings. (1985), Ahmad et al. However, despite development of several improved cultivars in different Vigna crops, biotic and abiotic stresses still remain the major constraints in realizing their true yield potential. " Inheritance of Protruded Stigma in Black Gram [Vigna mungo (L.) Hepper] " Save as: While plethora of genes conferring resistance/tolerance to these stresses have already been transferred from cultivated germplasm, wild genetic resources offer additional sources of useful alien variation which can be incorporated in cultivated Vigna through alien gene transfer. Mesophyll protoplasts of mung bean (Vigna radiata L. Wilczek) were electrofused with cell suspension-derived protoplasts of adzuki bean (V. angularis Ohwi & Ohashi) and subsequently cultured for several days. © 2014 Springer Science+Business Media, LLC. In vitro mutation in flower colour was detected in one branch of the same plant with 10 Gy irradiation. Host plant resistance is an economical, durable, environmentally safe and ecologically acceptable means of managing these pests. This is of two types: viz. 1, 2014 pp. Proc. 1, 2014 pp. Crossing between a Cultivar of the Green Gram and a Semi-Wild Relative of the Adzuki Bean, in Endemic Name “Bakaso”, Interspecific Hybridization in the Genus Phaseolus1, Interspecific crossability among four species of Vigna food legumes, Influence of different shades of light on pollination, seed set and seedling behaviour in mulberry. It was released under the name ‘Mash114’ for cultivation in the Punjab state. J. ii. In vitro flowering and in vitro pollination: methods that will benefit the orchid industry. Pollination requirements for several crops. No. ... Green gram, Black gram, Rice, Wheat, Groundnut, Soybean. In this paper, we further report our experience with in vitro flowering of Dendrobium Chao Praya Smile as a model system and discuss the usefulness of in vitro flowering and in vitro pollination for the orchid industry. All ray florets in each flower head and all flower heads in mutated branch were of the same colour and shape. Mechanism promoting cross-pollination. It indicates an injurious effect of pollen with accumulated exposure of the trees on seed germination. Can I return more than the $300/acre? You can request the full-text of this article directly from the authors on ResearchGate. Its cultivation in India is about 3.25 million hectares and an annual production is 1.45 million tons. If you do not receive an email within 10 minutes, your email address may not be registered, Heterokaryon performed a mixture of cytoplasms between fused parentals. July 15,1934 Authesis, Pollination, and Fertilization in Sorghum 125 TABLE 1.—Number of flowers blooming each hour in 4 panicles of Spur feterita during each day of their blooming periods Year Number of flowers opening at indicated hours Per- Day of blooming (no.) Black gram is a highly self-pollinated crop with cleistogamous Colours of epicotyl and stem bases were found to be linked. Min. This indicated wild germplasm having small tuber have potential to increase yield of large tuber cultivated type. A method for the in vitro pollination of chicory (Cichorium intybus L.) ovules was developed. Pollen from the red leaf parent contributed a smaller percentage of progeny (18%) compared with that from the white flesh (44%) or glandular leaf (38%) parents. The Urad crop is resistant to adverse climatic conditions and improves soil fertility by fixing atmospheric nitrogen in the soil. 4. This method greatly shortens the juvenile phase of orchids and, under optimal conditions, enables us to induce flowering and evaluate the flower quality about 5-6 months after seed germination. Apple: Cross pollination always needed to produce adequate fruit crop. Flowers could be produced in culture about 5-6 months after seed sowing by appropriate, The morphology of flowering of several cultivars of Dioscorea rotundata , Poir is described. In this study, we investigated genetics of domestication in zombi pea by QTL analysis using an F2 population of 139 plants derived from a cross between cultivated tuber form of V. vexillata (JP235863) and wild V. vexillata (AusTRCF66514). embryogenesis studies and ploidy analysis. . One fertile pod containing two hybrid seeds was obtained, when V. angularis was used as the male parent. 24 and 48 h after pollination.One fertile pod containing two hybrid seeds was obtained, when V. angularis was used as the male parent. Furthermore, a successful interspecific hybrid of V. mungo x V. angularis was accomplished through the use of intraspecific hybrid parents. is the male part of a flower and transferred to the flower’s female part called the stigma In addition, the hybrid exhibited two novel traits — the presence of racemose inflorescence and plant regeneration ability — not present in the parents. Many highly segregation distorted markers were found on LGs 5, 6, 7, 8, 10 and 11. Modes of Pollination The process by which pollen grains are transferred from anthers to stigma is referred as pollination. Due to a short life cycle, these are suitable as catch crops and also fit well in intercropping, mixed or relay cropping. Overall, pollination by opportunistic avian nectarivores amplified seed production per aloe ~7 and 10 times compared to insects and self-pollination, respectively. Pulse crops (Red gram, Black gram and Green gram) are basically self-pollinated in nature and don’t need any external pollination practices. Plant fertility was very poor in initial generations, but was improved gradually from F2 onwards. QTL analysis for 22 domestication-related traits was investigated by inclusive composite interval mapping in which 37 QTLs were identified for 18 traits; no QTL was detected for 4 traits. Crop Sci. and Devel. Black gram (Vigna Mungo L.) is popularly known as “Urad”, is one of the most important pulses crop, grown across India. Learn about our remote access options, Department of Plant Breeding and Genetics, Himachal Pradesh Agricultural University, Palampur 176 062 (HP), India. (1985), Goshen et al. Isolated nodal segments were established and shoot were multiplied on Murashige and Skoog (MS) medium supplemented with 0.5 mg L-1 6-benzyladenine (BA), 0.1 mg L-1 indole-3-aceticacid (IAA) and 1 mg L-1 gibberellic acid (GA 3). Interspecific hybridization of food legumes by conventional methods of plant breeding. Difficulties related to obtaining hybrids in grain legumes, and Phaseolus L. in particular, are reported in this research. Crossability was very poor in black gram × ricebean crosses, and only two to nine true hybrid plants were obtained. Classification of crop plants based on mode of pollination and mode of reproduction Mode of pollination and reproduction Examples of crop plants A. Autogamous Species 1. Seedling phenotypes were scored to determine the fraction of the progeny that resulted from each day’s pollination. Colours of epicotyl and stem bases were found to be linked. In fact, there are wild or wild-like species more resistant to stresses or diseases than the cultivated ones. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. ISSD Myanmar organized this training with the cooperation of Department of Agriculture, Department of Agricultural Research and WHH. (1995), Fiala (2006), L. culinaris × L. lamottei Fiala (2006) L. culinaris × L. nigricans Cohen et al. Mungbean Symp., Asian Vegetable Res. I. Autogamy Transfer of pollen grains from the anther to the stigma of same flower is known as autogamy or self pollination. All rights reserved. Pollinated pistils were treated with gibberellic acid (GA3) (70 p.p.m.) In the succeeding generations the hybrid condition gives way to pure breeding as a result of natural self-pollination, and families derived from different F2 plants begin to display their unique character. One of these seeds germinated and a partly fertile interspecific hybrid was obtained. For genetic improvement of cultivated vignas, mainly cultivated germplasm and exotic lines have been used so far. 14 No. Interestingly, 2 QTLs each for tuber width and tuber weight detected on LG2 and LG4 were located at similar position and wild allele increased tuber width and weight. 1991, Verma and Brar 1996. Pubescence of epicotyl, stem, leaf margins and pod, and the colour of the mature pod, characteristics of the black gram × green gram derivative, were also expressed in the hybrid. Viable seeds were obtained from the interspecific crosses of V. radiata x V. mungo, V. radiata x V. umbellata and V. mungo x V. angularis. 1. Its hybridity was confirmed at the seedling stage based on the presence of the green epicotyl colour of the adzuki bean. This ensures self fertilization. Valued for their grains with high and easily digestible proteins, these crops are also known as forage, green manure, and cover crops. Twenty-four uniform progenies, bulked in F7, were evaluated for yield potential. of gamma rays and multiplied on the same medium. In this context, cross-pollinations are for great interest. These are grown mainly in the warm temperate and tropical regions of the world. Hybrid plants were obtained from cultured embryos for the interspecific crosses of V. radiata x V. angularis, V. umbellata x V. angularis and V. angularis x V. umbellata. Al-Yasiri, S. A., and D. P. Coyne, 1966: Interspeci®c hybridization in the genus Phaseolus. Hence the breeding cycles of orchid were reduced significantly. Using one of the hybrids, Dendrobium Chao Praya Smile, as a model system, methods for in vitro flowering and in vitro pollination are described. When the crop matures, the leaves turn yellowish and present a nearly dried up appearance. 04. Working off-campus? Genetics of domestication have been investigated in most of cultivated Vigna crops by means of quantitative trait locus (QTL) mapping. : 307 The dot represents the main axis, green structure below is the subtending bract.Calyx (green arcs) consists of five free sepals; corolla (red arcs) consists of five fused petals.Antepetalous stamens are joined to petals by hairy filaments. ... During crosses between Vigna unguiculata L. Walpers and V. vexillata (L.) A. A good gram crop in case of desi (black varieties) gives an output of 15 to 20 quintals yield per hectare and in case of Kabuli varieties gives about 25 to 30 quintals yield per hectare. Black gram [Vigna mungo (L.) Hepper] is a tropical crop belonging to the Asiatic Vigna ... 1974). There are 2-3 ovules pod-1 but on an average 1-2 seeds pod-1 are produced. Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. However, high incidence of insect pests in these crops is a major constraint in achieving their potential productivity and resulting in yield instability over the years. Autogamy is the closest form of inbreed Chronically irradiated pollen was collected from cut-branches with male strobili of Kumotoosi that had been grown in the gamma field since 1962. Rich) is an underutilized crop belonging to the genus Vigna.
