The present investigation was undertaken to assess the genetic variability governing seed quality traits in soybean (Glycine max L.). A total of 50 diverse genotypes obtained from AICRP-Soybean, JNKVV, Jabalpur, were evaluated during Kharif 2021–22 and 2022–23 at the agricultural farm of Rabindranath Tagore University, Raisen (M.P.), using a randomized complete block design with three replications. Significant genotypic differences were observed for all 24 traits assessed, including phenological, morphological, physiological, and seed quality parameters, indicating ample genetic variation among genotypes. Notably, days to 50% flowering, days to maturity, and flowering-to-maturity duration exhibited high genotypic variability, essential for tailoring maturity to specific agro-ecological zones. Morphological traits like plant height, number of branches, and pods per plant significantly influenced productivity potential. Among seed yield and physical quality traits, seed yield per plant and 100-seed weight showed strong genetic control, providing scope for effective selection. Physiological traits such as hydration and swelling coefficients, seed vigor indices, and electrical conductivity demonstrated significant variability, revealing key insights into seed longevity and field performance. Particularly, electrical conductivity and seed coat cracking, both critical indicators of seed viability, were highly significant, underlining the importance of structural seed traits. The combined analysis confirmed that traits with high heritability and low environmental influence can serve as reliable selection indices for breeding high-yielding and resilient soybean cultivars. The findings provide a robust foundation for future genetic improvement programs targeting both productivity and seed quality enhancement in soybean.
