Abstract
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.
