Abstract:
Soybean [Glycine max (L.) Merrill] is the world’s leading source of oil and protein. It has the highest protein content of all food crops and is second in terms of oil content among food legumes. Study on genotype x environment interaction (GE) and stability of twenty-one newly developed lines derived from the cross between five gain and three vegetable soybean varieties. Analysis was conducted for yield contributing traits with oil and protein at the green stage over three environments in Maharashtra during Kharif 2019. Analysis indicated that the AMMI (AMMI1-AMMI5) were highly significant (P< 0.01) for all the traits. The partitioning of TSS (total sum of squares) exhibited that the genotypic and environment effect was a predominant source of variation followed by GE interaction. For green pod yield per plant four lines and green seed yield per plant five lines were identified as stable lines among which line VS-5-276-17 had the best performance. Among the stable performing lines for 100 green seed weight per plant line, VS-2-128-17 had the highest reading. For oil and protein content at the green stage line, VS-4-266-17 was identified as better-performing as well as stable for three locations, The objectives of the experiment were to determine the magnitude of GEI and stability of newly developed lines and thereby identify widely and/or specifically adapted genotypes under Maharashtra conditions. Such an outcome of the present study could be recurrently employed in the upcoming research to define predictive, more rigorous recommendation strategies as well as to explain stability concepts for recommendations for vegetable soybean.
