Abstract

There was a significant variation for genotypes and genotype x environment interaction for seed yield in cluster beans. The linear as well as non linear components were significant. Genotypes guar 46-P7 and guar 44-P15-2 were stable under fluctuating environmental conditions. Genotypes guar 46-P24-1, 4210(26), guar 46-P16-2, guar 44-P10 appeared to be the best for favourable growing seasons, while guar 46-P3-1, guar 46-P17-1 and guar 46-P27-1 were suitable for unfavourable growing conditions. The exploitation of these genotypes in a breeding programme will help in improving the productivity of the crop in its growing areas.
