- Abstract
The additive main effects and multiplicative interaction (AMMI) model was used to analysis the yield and yield component traits data of 25 soybean genotypes grown in three environments(Normal condition with rainfed condition, high plant population with rainfed condition and normal population with excess moisture). Main effects due to environments (E)and genotypes (G) were found significant for the all traits. The G × E interaction was significant for most of the traits, except days to 50% flowering, days to maturity and 100 seed weight (g). Gollob's test declared two components, Principal Component Analysis1 (PCA 1) and PCA 2, statistically significant (P < 0.01) for all the traits, except days to 50% flowering and days to maturity studied. The contribution of PCA 1 (99.6%) for G x E sum squares was greater for Days to maturity followed by Days to 50% flowering. The highest contribution for PCA 2 was (36.2%) for Grain yield per plant (g). In the present study, statistical analysis of yield trials of soybean under three environments with the AMMI model has revealed practical implications for plant breeding research towards in soybean.
