Abstract

A study was undertaken during 1995–1997 at three locations to judge the stability for 6 traits. The pooled analysis of v.uiance showed differential behaviour of genotypes over the environments. Vanation due to glmotypes (G), environments (El, G x E, and environment plus genotype x environment interaction was significant for all the characters. None of the genotypes was stable for all the characters. The Henotypes Bonneville and Azad P1 were found suitable to be stable for days to flowering, pods/plant. seeds/pod and pod weight/plant having high mean value, regression coefficient close to unity with least deviation (non significantl from linear regression(S2di). These genotypes could be utilized for developing high yielding stdble and widely adapted genotypes of pea.
