Mungbean (Vigna radiata (L.) R. Wilczek, or green gram) is important tropical and sub-tropical legume and a rich source of dietary protein and micronutrients. It belongs to the family Leguminosae, subfamily Papilionoideae, clade Millettioid [1], and is a tropical legume crop species that is cultivated in Asia, Africa, and America [2]. the black gram (Vigna mungo (L.)) with two main differences: the corolla of Vigna mungo is bright yellow while that of Vigna radiata is pale yellow; mung bean pods are pendulous whereas they are erect in black gram. Blackgram [Vigna mungo (L.)Hepper] is an annual, short duration, self pollinated, leguminous crop belong to family leguminoseae sub family Papilionaceae with a chromosome number of 2n=2x=22, it is commonly known as urd bean. Breeding objectives 1. A study was undertaken on the variation in chromosome number of cells from callus tissues originating from cotyledon, hypocotyl and embryonal axis explants of Vigna mungo. 313 001. The range of median and submedian chromosomes in chromosome number in many Vigna species. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Two varieties of Vigna mungo viz. The low frequency of reports of 2n = 18 in the tribe Phaseoleae and in the family … V. mungo These numer- the wild taxa ranges from 4 to 18 while in cultivated taxa the ical alterations may be attributed to the occurrence of mitotic number ranges from 8 to 14. non-disjunctions, causing the appearance of aneuploid cells The karyotypes of all the materials studied were found to [16]. Blackgram (Vigna mungo (L.) Hepper) popularly known as urdbean or mash, is a grain legume domesticated from V. mungo var. Restricted gene flow between the four species, Vigna radiata, V. mungo, V. umbellata and V. angularis limits the potential for improved production and adaptation of these species in different agroecological systems. L. cultivar ‘Azad-2’ with the root-knot nematode and treated with two biofertilizers viz. Sterility is the main problem. The least SSR density was found on chromosome 6 (411.3).

Vigna mungo (L.) Hepper or black gram is a diploid plant with 2n = 2x = 22 chromosomes. It is popularly known as “urd bean and mash” is an important short duration and selfpollinated Kharif legume crop and is an important part of Indian diet. Total length of diploid complements and range of chromosome length were more or less same in the two varieties. Mungbeans are a good source of dietary protein, folate and iron. Mung bean is sown on lighter soils than black gram (Göhl, 1982). It belongs to family leguminoseae with chromosome number 2n=2x=22. 1982. An induced mutant, multiple-organ gigantism (MOG), of black gram (Vigna mungo) has been obtained, which shows gigantic leaves, fruit, seed, and architecture (plant height) but lower number of pods per plant. Total length of diploid complements and range of chromosome length were … In this investigation the nature and extent of DNA variation between thirteen diploid and one polyploid species have been estimated. These traits are a pleiotropic effect of a single recessive gene, mog. India ABSTRACT A study on the variation in chromosome number of the callus cells derived from immature embryo explant of Vigna mungo L. Hepper was undertaken. To Green bean cultivation is relatively easy with a small risk of failure. Vigna mungo x V.radiata for increasing pod length, digestibility. It produces about 1.5 to 1.9 million … It had been reported earlier that restriction of gene flow between these species was partly due to hybrid inviability and partly due to chromosomal differentiation.

Abdul Ghafoor( and Muhammad Ishtiaq (- Plant Genetic Resources Institute (PGRI), National Agricultural Research Centre (NARC), Islamabad, Pakistan. Although Jingnong 6 and Kyungwonpat cultivars were from the same species, at chromosome level substantial variation in SSR abundance was observed. From the results, it was evident that . The chromosome number showed a wide range … Blackgram is reported to be originated in India (Zukovskiji, 1962). … silvestris (Lukoki, 1980). 1989; Dongre et al. The present study deals with karyotypic analysis in 10 taxa belonging to the genus Vigna. Black gram is an economically important Vigna species, which provides high-protein food [3]. It belongs to family leguminosae with chromosome number 2n = 2x = 22. In this study we employ GWAS to examine the genetic basis of variation in several important traits in mungbean, using the mini-core collection established by the World Vegetable Center, which includes 296 accessions that represent … The plants were grown in soil at N50 and N100 doses of urea. silvestris is reported to be immune to bru-chids (Fujii et al.

Wild species of Vigna are known to exhibit great range of phenotypic and genotypic diversity leading to development of several varieties and cultivars. The cultivated Asiatic Vigna species belong to the sub-genus Ceratotropis, a fairly distinct and homogeneous group, largely restricted to Asia, which has a chromosome number of 2n = 22 (except V. glabrescens, 2n = 44).There are seven cultivated species within the sub-genus, including mung bean or green gram (V. radiata), black gram or urad bean (V. mungo), adzuki bean (V. … Embryo Culture and Chromosome Doubling Results Crosses Green Beans and Black Beans Resume of M.

Karyotypes in some pulse crops. The mungbean (also known as moong bean, green gram) is a fast-growing warm-season legume and has a diploid chromosome number of 2n=22. Two varieties of Vigna mungo viz. The chloroplast genome of this species has not been previously reported. Blackgram is reported to be originated in India (Zukovskiji, 1962).India is the world’s largest producer as well as consumer of blackgram. A systematic genetic analysis of colchitetraploids of Vigna radiata and V. mungo in three different generations (C 1, C 2 and C 3) was made using karyomorphology of chromosomes and heterochromatin distribution pattern among them.Autotetraploid of both species were produced using aqueous colchicine (0.15 and 0.20%) and maintained through three successive generations (C 1, C 2 … - Tropical grain legumes, such as black gram, Vigna mungo, and green gram, Vigna radiata (L.)

Vigna mungo . Both the varieties were found to possess 2n =22 metacentric chromosomes. Bruchid beetles are an important storage pest of grain legumes. Cytogenetical investigations, so far, on the organisation and evolution of the genomes of Vigna species have proved difficult due to small chromosome size, large chromosome number and uniformity in chromosome shape and size within and between the complements. 1. In India the area production and productivity of blackgram was 4.49mha with 2.93 m tonne … It also contributes 76% carbohydrate 3-5% Fiber, 1.74% … Determination of the chromosome numbers of root tip tissue (2n=22) and nodule tissue revealed that nodule tissue contained both diploid and tetraploid cells but no other degrees of polyploidy. infect mungbean (Vigna radiata) at low levels in the field, multiply during grain storage and can destroy seed stocks in a few months. Few plants obtained revert back to parental form. Uninoculated untreated plants served as control. Email: [email protected] Abstract Seeds of two varieties, PU-19 and T-9, of urdbean (Vigna mungo (L.) Hepper) were treated with four … In Jingnong 6, maximum markers were found on chromosome 1 (14 964), … However, none of the maps resolved 11 LGs, which is the haploid chromosome number of mungbean. Organ size and architecture of plants are important traits affecting crop yield and agronomic practices.

Pseudomonas fluorescens strain CHA0, and . in wild mungbean (Vigna radiata var. 20 per page . Resistance against bruchid beetles has been found in wild mungbean V. radiata var. The variation induced by 2,4-D and kinetin treatments at 10, 20 and 30 days was studied in all three explants. Mungbean is mainly cultivated today in China, India and Southeast Asia but can be found in dry regions within Southern Europe and United States. This legume species was moved from the genus It belongs to family leguminoseae with chromosome number 2n=2x=22.Blackgram is reported to be originated in India. Introduction. There has been confusion on the taxonomic status of Vigna mungo and Vigna radiata; because they are closely related it was proposed that they be grouped into a single species. 20 per page; 50 per page; 100 per page; Search Results.
