Abstract

The performance of 11 diverse promising genotypes of Indian rape (Brassica campestris L. var. toria) evaluated for genotype x environment interactions for seed yield in four environments revealed that the genotypes interacted considerably with environmental conditions. Both linear and non-linear components were significant. Genotypes Sangam, TGC 1, PT 507 B and T 9, performed better especially in high yielding environments. Out of these, except TGC 1, all had large deviation values from regression. Genotypes TLC 1, TK 6 and TH 63 were found promising under less favourable situations. PT 43 had almost unit responses to the changing environmental conditions and was a stable genotype; However, it was a low yielder.
