Abstract
Characterizing germplasm is essential for establishing a solid foundation for successful crop improvement programs. The present study aimed to develop essential morphological descriptors and descriptor states for Vigna stipulacea (Lam.) Kuntze, which would facilitate its characterization, evaluation, valuation, and utilization. The utilization of this species as grain and forage legumes is well-documented in the literature. To fulfil the requirements of the current research and provide comprehensive and refined descriptors, a set of agro-morphological descriptors comprising qualitative and quantitative traits was identified. Traits such as leaf shape and size, stipule color, peduncle length, pigmentation, pod color (both immature and mature), and seed color exhibited significant variability. Through a critical analysis of the variation observed in the accessions conserved in the Indian national genebank, a standardized set of 55 minimum agro-morphological descriptors (39 qualitative and 16 quantitative) has been proposed and documented for the characterization and preliminary evaluation of Vigna stipulacea germplasm.
