GENOTYPE X ENVIRONMENT INTERACTIONS FOR SEED YIELD IN CLUSTERBEAN

Abstract

Genotype x environment interaction was investigated for grain yield in 12 branched genotypes of clusterbean (Cyamopsis tetragonaloba (L.) Taub), under rainfed conditions, during monsoon seasons (1979-1981). There was a significant variation for geno- types and genotype X environment interaction for grain yield. The linear as well non linear components were significant and between the two, linear component was higher in magnitude. The genotype 'Durgapura Saffed was the most stable genotype under fluctuating environmental conditions Genotypes 'HFG 556 and HFG 189 were best for favourable growing seasons while 'DSE1J' and 'DSE16J were suitable for unfavou- rable growing seasons.
