A set of 47 urdbean genotypes including 12 promising varieties and 34 popular land races and a popular OUAT variety “Ujala” (standard check) were characterized for genetic variation based on molecular markers and morpho-economic traits. The molecular marker- based genotyping revealed a tremendous higher level of polymorphism (97.05%) with high average PIC (polymorphic information content) value (0.75). ISSR 1357 was considered highly informative that revealed the highest PIC (0.87) and marker index value (MI:5.25). An 840 bp allele (band) was characteristic to Kantapada local - A, Kendrapada local-D, and Nayagarh local - C. Such genotype- specific finger-printing may serve for reliable varietal characterization and elimination of duplicates. The test genotypes were grouped into six distinct clusters. TU 10-13, LBG 623, TAU 1, OBG 33, LBG 17 and PU 31 were highly divergent. PU 31 had inherent high yield potential (˃5.0q/ha) with known YMV resistance. The above divergent high yielding test genotypes may serve as candidate varieties for further genetic improvement using recombination breeding.

揭示迷你小核心种质的遗传变异（Vigna mungo（L.）Hepper）

根据分子标记和形态经济性状，鉴定了47种urdbean基因型，包括12个有前途的品种和34个受欢迎的陆地种族和OUAT受欢迎的品种“ Ujala”（标准检查），以进行遗传变异。基于分子标记的基因分型显示出很高的多态性水平（97.05％），平均PIC（多态信息含量）值较高（0.75）。ISSR 1357被认为具有很高的参考价值，显示出最高的PIC（0.87）和标记指数值（MI：5.25）。一个840 bp的等位基因（条带）是Kantapada本地-A，Kendrapada本地-D和Nayagarh本地-C的特征。这种特定基因型的指纹可以可靠地进行品种鉴定并消除重复。测试基因型被分为六个不同的簇。TU 10-13，LBG 623，TAU 1，OBG 33，LBG 17和PU 31分歧很大。PU 31具有固有的高产量潜力（˃5.0q/ ha），具有已知的抗YMV性。以上不同的高产测试基因型可以用作候选品种，以使用重组育种进一步遗传改良。
