Abstract

An evaluation of twenty grain sorghum entries comprising fifteen varieties and five hybrids, in eight different evironments, showed significant genotype x environment interactions for all the eight characters studied. Both linear and non-linear components of GXE were significant. KS 6312, CSH 1, CSHS, COH 3 and KT were identified as suitable genotypes for favourable environments. CSH 9 was found to be the most stable genotype with the least mean square deviation. "b" value nearer to unity and high grain yield.
