Seasonal variations in soybean (Glycine max L. Merrill) genotypes under different environments

Author(s): Nutan Verma and Tajwar Izhar
Abstract:
Stability analysis was carried out in eight soybean genotypes including checks over eight environments (four locations for two years) to identify phenotypically stable genotypes that could perform more or less uniformly under different environmental conditions for various economic traits. Pooled analysis of variance for stability in the performance of different genotypes of soybean was significant for number of branches per plant, number of pods per plant, 100 seed weight (g), days to maturity, number of seed per pod, seed yield (q/ha), protein content (%) and oil content (%) indicating that the materials selected possessed significant variation for all the characters under study. Significant mean square due to environment confirming that the environments selected were variable and random and influenced the expression of most of the traits selected for stability studies. Mean squares arising due to GxE interaction were significant for most of the traits except plant height (cm) and days to 50 % flowering revealing that most of the characters under study were having differential response to the changing environments and the characters showing non-significant mean square revealed, by and large, less effect of the changing environments. In the present study, the genotypes BS-1, BAUS-31 and RAUS-5 having higher mean could be recommended for cultivation across environments on the basis of stability performance for various economic traits.
