Genotype selection for agronomical trait - seed yield in kewachh {Mucuna pruriens (L.)}

Mucuna {Mucuna pruriens (L.)} is a climber plant belonging to the family 'Fabaceae', found as the wild/cultivated form in subtropical/tropical areas worldwide. The present experiment/study was carried out to determine the adaptability and stability among forty genetic stocks of velvet beans assembled from different places in India for high and stable seed yield by using AMMI analysis. Five high seed yielding and most stable genetic stocks, namely G-37, G-30, G-8, G-23 and G-18, were identified based on seed yield performance for commercial exploitation. The performance-wise mean data of seed yield indicated that one genotype G-37 = 57.03 (ql/ha) was selected for stable and high seed yield. Based on the AMMI model, these five genotypes of Mucuna showed the widest adaptability and stability over the years.
