STABILITY ANALYSIS OF PUTATIVE MUTANT SOYBEAN LINES (Glycine max (L.) Merr) in Four Environments

Abstract

Breeding program for high yielding varieties of soybean through mutation breeding conducted by BAU has produced M9 generation of putative mutant lines. The aim of this research was to evaluate the stability and adaptability of putative mutant lines in some environments. Evaluation was done on 10 putative mutant lines and two national varieties as control, i.e. Argomulyo and Tanggamus. The research was conducted in Bogor and Purwakarta, West Java in Randomized Complete Block Design (RCBD) with three replications nested in each environment. The results showed that M200-13-47-7 and M200-93-49-6 were stable lines with general adaptability. M100-46-44-6, M100-96-53-6, and M150-7B-41-10 had specific adaptation on marginal environment, meanwhile M200-39-64-4 had specific adaptation on optimum environment. M150-29-44-10 and M200-93-49-13 had the specific adaptations in the dry season in Bogor and Purwakarta, respectively.
