Studies on Genotype x Environment interaction and stability for yield in soybean (Glycine max (L.) Merrill)
Abstract
The present investigation was carried out to study stability performance over three environments for yield and its components in seven elite pipeline soybean genotypes using a randomized complete block design. The mean sum of squares due to genotype and environments (linear) differed significantly. However, higher magnitude of mean squares due to environments indicated considerable differences between environments for all traits. Similarly, the MSS for Genotype x Environment was found to be significant for all the traits expect for number of pods per plant. Based on the stability parameters the genotype Dsb-21 was found to be widely adapated whereas Dsb-19 and JSS-335 a popular variety among the farmers performed better under favorable conditions.
