    vigna mungo chromosome number

    New chromosome number in the genus Vigna Savi (Leguminosae-Papilionoideae) by E. R. Forni-Martins (*) Abstract. 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 . silvestris (Lukoki, 1980). Blackgram (Vigna mungo (L.) Hepper) popularly known as urdbean or mash, is a grain legume domesticated from V. mungo var. To Total length of diploid complements and range of chromosome length were … 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. The chloroplast genome of this species has not been previously reported. In this investigation the nature and extent of DNA variation between thirteen diploid and one polyploid species have been estimated. The low frequency of reports of 2n = 18 in the tribe Phaseoleae and in the family … Both the varieties were found to possess 2n =22 metacentric chromosomes. Black gram is an economically important Vigna species, which provides high-protein food [3]. Name Reference IPCN Reference Gametophytic Count Sporophytic Count Country ; Vigna mungo (L.) Hepper: Sharma, P. C. & P. K. Gupta. Two varieties of Vigna mungo viz. V. mungo ... More number of Back crosses suggested. … In India the area production and productivity of blackgram was 4.49mha with 2.93 m tonne … Vigna mungo var. Pseudomonas fluorescens strain CHA0, and . Email(: [email protected] 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]. Few plants obtained revert back to parental form. 1. 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. 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. The most comprehensive map consists of 255 loci with an average distance between the adjacent markers of 3 cM. 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. Bruchid beetles are an important storage pest of grain legumes. Vigna mungo is cultivated in approximately 5 million hectares worldwide. Vigna mungo (L.) Hepper or black gram is a diploid plant with 2n = 2x = 22 chromosomes. In this study, we sequenced the genome and transcriptome of the V. mungo chloroplast. Embryo Culture and Chromosome Doubling Results Crosses Green Beans and Black Beans Resume of M. Kosmiatin and I. Mariska CHAPTER I Preliminary 1.1 Background Mung bean (Vigna radiata L. Wilczek) including crops that have long been cultivated in Indonesia (Arora and Mauria 1993). It produces about 1.5 to 1.9 million … The chromosome number showed a wide range … 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. Since all … Although Jingnong 6 and Kyungwonpat cultivars were from the same species, at chromosome level substantial variation in SSR abundance was observed. Vigna mungo L. Hepper) popularly known as urdbean or mash, is a grain legume domesticated from V.mungo var. Karyotypes in some pulse crops. 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. Callosobruchus sp. Green bean cultivation is relatively easy with a small risk of failure. sublobata) and cultivated V. radiata through genotyping by sequencing and quantitative trait locus analysis. silvestris (Lukoki, 1980). In Jingnong 6, maximum markers were found on chromosome 1 (14 964), … 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. 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. Wild species of Vigna are known to exhibit great range of phenotypic and genotypic diversity leading to development of several varieties and cultivars. Number of results to display per page. in wild mungbean (Vigna radiata var. 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 … Identification of single nucleotide polymorphism markers associated with resistance to bruchids (Callosobruchus spp.) Resistance against bruchid beetles has been found in wild mungbean V. radiata var. 313 001. Taxonomy. 1996). Bacillus subtilis . silvestris is reported to be immune to bru-chids (Fujii et al. It belongs to family leguminoseae with chromosome number 2n=2x=22. silvestris. The least SSR density was found on chromosome 6 (411.3). Blackgram is reported to be originated in India (Zukovskiji, 1962).India is the world’s largest producer as well as consumer of blackgram. Barimash-1 and Barimash-3 were cytologically studied after staining with orcein and CMA. Introduction. These traits are a pleiotropic effect of a single recessive gene, mog. 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]. It is grown mainly in rainy and/or summer seasons. From the results, it was evident that . The range of median and submedian chromosomes in chromosome number in many Vigna species. Total length of diploid complements and range of chromosome length were more or less same in the two varieties. 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. Advertisement.
