Lablab purpureus (L.) Sweet is one of the most important underutilized legume vegetable crops, which exhibits broad genetic variability in multiple characteristics such as the habit, pigmentation of the stem, and color of the pod. In the past, researchers paid very little attention to the systematic crop improvement of L. purpureus. In the present study, fifty accessions of L. purpureus collected from different places of South India were analyzed for yield, and attributes of morphological, and biochemical factors. Nutritional and anti-nutritional factors analyzed using the standard protocol, revealed significant variations for all the characters studied. Compared to the popular leguminous vegetables, the nutritional content of all accessions was found to be high, whereas anti-nutritional factors were very low. The differences in phenotypic and genotypic coefficient of variations were compared for different traits, and it was found to be very narrow for almost all the characters studied. The fifty genotypes involved in the study significantly varied in the number of pod/inflorescence, length and width of the pod, number of flower/inflorescence, and length of the peduncle. So, these observations can be used as baseline data for selecting parental lines for future improvement of L. purpureus. Giving importance to neglected and underutilized crops effectively maintain a diverse and healthy diet and combat micronutrient deficiencies.

Lablab purpureus (L.) Sweet 是最重要的未被充分利用的豆类蔬菜作物之一，它在习性、茎的色素沉着和豆荚的颜色等多种特征上表现出广泛的遗传变异性。过去，研究人员很少关注L. purpureus的系统性作物改良。在本研究中，五十种L. purpureus对从印度南部不同地方采集的植物进行产量、形态和生化因子属性分析。使用标准方案分析的营养和抗营养因素揭示了所研究的所有特征的显着差异。与流行的豆类蔬菜相比，发现所有种质的营养成分都很高，而抗营养因子却很低。比较不同性状的表型和基因型变异系数的差异，发现几乎所有研究的性状都非常狭窄。研究中涉及的 50 种基因型在豆荚/花序的数量、豆荚的长度和宽度、花/花序的数量和花序梗的长度方面存在显着差异。所以，L. purpureus。重视被忽视和未充分利用的作物，有效地维持多样化和健康的饮食，并对抗微量营养素缺乏症。
