Thirty five indigenous and exotic genotypes of pea were evaluated under eight environments for stability analysis for seed yield and its components using Eberhart and Russel's (1966) model. Pooled analysis of variance for all thirteen characters indicated high differences among the genotypes and environments. The linear component was observed to be significant for all the characters suggesting that the prediction of performance of genotypes was possible across environments. Genotypes EC 341995, NIC 11249, BDJ 42–174, DMR-ll and EC 381864 were observed to be stable and high yielding under favourable conditions while genotype DMR-l would perform better in adverse environmental conditions and thus could be utilized as donor parent to breed higher yielding line for poor environment.
