Vegetable soybean production is dependent on the development of vegetable type varieties that would be achieved by the use of germplasm to evolve new agronomically superior yielding vegetable type with beneficial biochemical traits. This can be accomplished by a better understanding of genetics, which is why the research was conducted to reveal the quantitative genetics of vegetable soybean genotypes. Genetic variability of main morphological traits in vegetable soybean genotypes and their divergence was estimated, as a result of the magnitude of genotypic variation (GV), and phenotypic variation (PV) of traits varied among the genotypes. All traits showed high heritability () associated with high genetic advance percentage mean (GAM). Therefore, these variable traits are potential for genetic improvement of vegetable type soybean. Genetic diversity is the prime need for breeding, and the magnitude of genetic diversity values were maximized among specific genotypes. Eight clusters were found for all genotypes; cluster VIII and cluster I were considered to have the most diversity. Cluster VIII consisted of two genotypes (GM-6 and GM-27), based on the mean outcomes of the high yield attributing traits. Hence, these two (GM-6, GM-27) genotypes can be advanced for commercial cultivation; furthermore, other genotypes can be used as source of breeding lines for genetic improvement of vegetable soybean.
毛豆生产依赖于蔬菜型品种的培育，这可通过利用种质资源来实现，从而培育出具有优良农艺性状和有益生化特性的新型高产蔬菜型大豆。这可以通过更好地理解遗传学来实现，这就是开展此项研究以揭示毛豆基因型数量遗传学的原因。由于各基因型中性状的基因型变异（GV）和表型变异（PV）程度不同，对毛豆基因型主要形态性状的遗传变异性及其差异进行了估计。所有性状均表现出高遗传力（），且遗传进展百分比均值（GAM）较高。因此，这些可变性状具有毛豆遗传改良的潜力。遗传多样性是育种的首要需求，特定基因型间的遗传多样性值达到最大。所有基因型共分为8个类群；第八类群和第一类群被认为具有最大的多样性。基于高产相关性状的平均结果，第八类群由两个基因型（GM - 6和GM - 27）组成。因此，这两个（GM - 6、GM - 27）基因型可用于进一步商业化种植；此外，其他基因型可作为毛豆遗传改良育种系的来源。
