), India *Corresponding author. 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. 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. 313 001. Blackgram is an annual leguminous crop belongs to family Fabaceae and sub-family Papilionaceae with a chromosome number 2n=22 (Dana, 1980) and originated from Indian continent [De Candolle, 1882, Vavilov, 1926]. Barimash-1 and Barimash-3 were cytologically studied after staining with orcein and CMA. sublobata) and cultivated V. radiata through genotyping by sequencing and quantitative trait locus analysis. A Comparative Study of Chromosomal Aberrations in Vigna mungo Induced by Ethylmethane Sulphonate and Hydrazine Hydrate S. Goyal* and S. Khan Department of Botany, Aligarh Muslim University, Aligarh – 202002 (U.P. 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. However, none of the maps resolved 11 LGs, which is the haploid chromosome number of mungbean. Uninoculated untreated plants served as control. silvestris (Lukoki, 1980). 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. Chromosome 3 had minimum number of repeats (6579) having maximum SSR density per Megabase (Mb) (573.2). The plants were grown in soil at N50 and N100 doses of urea. The most comprehensive map consists of 255 loci with an average distance between the adjacent markers of 3 cM. L. cultivar ‘Azad-2’ with the root-knot nematode and treated with two biofertilizers viz. strain Bs-5. Green bean cultivation is relatively easy with a small risk of failure. In Jingnong 6, maximum markers were found on chromosome 1 (14 964), … Callosobruchus sp. Organ size and architecture of plants are important traits affecting crop yield and agronomic practices. 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. Abstract. 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. Email(: ghafoor59@hotmail.com. INTRODUCTION. - The chromosome number of Vigna candida (Vellozo) Mar&chal, Mascherpa & Stainier was determined as 2n=18, being the first report of this number for the genus Vigna (2n= 20, 22 and 24). The least SSR density was found on chromosome 6 (411.3). silvestris is reported to be immune to bru-chids (Fujii et al. silvestris. Wild species of Vigna are known to exhibit great range of phenotypic and genotypic diversity leading to development of several varieties and cultivars. 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. The variation induced by 2,4-D and kinetin treatments at 10, 20 and 30 days was studied in all three explants. Resistance against bruchid beetles has been found in wild mungbean V. radiata var. Black gram is an economically important Vigna species, which provides high-protein food [3]. 1996). 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. It also contributes 76% carbohydrate 3-5% Fiber, 1.74% … The low frequency of reports of 2n = 18 in the tribe Phaseoleae and in the family … Mungbeans are a good source of dietary protein, folate and iron. It produces about 1.5 to 1.9 million … Two varieties of Vigna mungo viz. Advertisement. Vigna mungo is cultivated in approximately 5 million hectares worldwide. The range of median and submedian chromosomes in chromosome number in many Vigna species. The chromosome number showed a wide range … 1989; Dongre et al. Blackgram (Vigna mungo (L.) Hepper) popularly known as urdbean or mash, is a grain legume domesticated from V. mungo var. Few plants obtained revert back to parental form. Blackgram is reported to be originated in India (Zukovskiji, 1962).India is the world’s largest producer as well as consumer of blackgram. Karyotypes in some pulse crops. In India the area production and productivity of blackgram was 4.49mha with 2.93 m tonne … Vigna mungo x V.radiata for increasing pod length, digestibility. 20 per page . Total length of diploid complements and range of chromosome length were more or less same in the two varieties. Since all … 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. 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. Mung bean is sown on lighter soils than black gram (Göhl, 1982). 1. - Tropical grain legumes, such as black gram, Vigna mungo, and green gram, Vigna radiata (L.) R. 1982. 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 … Search Menu; Account Menu; Menu; Sign In ... only about half of these genome assemblies were anchored to chromosomes. … Introduction. Bruchid beetles are an important storage pest of grain legumes. Identification of single nucleotide polymorphism markers associated with resistance to bruchids (Callosobruchus spp.) This legume species was moved from the genus in wild mungbean (Vigna radiata var. Mungbean (Vigna radiata L. Wilzeck) known as green gram and mashbean (Vigna mungo L. Happer) as black gram are widely cultivated pulse crops belonging to family Fabaceae.In cereal based cropping system, these pulses are being consumed as supplemental crops. None has been found more suitable for transformation as in of methods developed so far for Vigna species, ex- Vigna radiata (Jaiwal et al ., 2001; Sonia et al ., 2007), cept in V. angularis (Yamada et al ., 2001), explored V. mungo ( Saini et al ., 2003, Saini and Jaiwal, 2005) this possibility. The chloroplast genome of this species has not been previously reported. New chromosome number in the genus Vigna Savi (Leguminosae-Papilionoideae) by E. R. Forni-Martins (*) Abstract. 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]. Mungbean is mainly cultivated today in China, India and Southeast Asia but can be found in dry regions within Southern Europe and United States. cM), number of markers (102-255 markers), number of linkage groups (LG) (12-14), and level (12-30.8%) and regions of marker distortion. Vigna mungo var. 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 … Barimash-1 and Barimash-3 were cytologically studied after staining with orcein and CMA. The present study deals with karyotypic analysis in 10 taxa belonging to the genus Vigna. It belongs to family leguminosae with chromosome number 2n = 2x = 22.
