The stability analysis in 30 toria genotypes for six characters (No. of primary and secondary branches, seeds/siliqua, 1000-seed weight, and seed yield/plant), grown over three locations on two dates of sowing thus making six environments, was done and significant G × E interactions were revealed. The linear G × E component for primary and secondary branches, seeds/siliqua, 1000-seed weight, and seed yield was significant and predictable. This indicated that the performance of genotypes over environments for these traits could be predicted. The nonlinear component of G × E was significant for siliquae/plant, 1000-seed weight, and seed yield. Genotypes TH 69, TH 84, TK 8403, TGC-2, and Sangam showed average stability.
