Abstract

Genotype xenvironment interactions, stability parameters for yield and its components in peas were evaluated by growing 6 pre-released varieties in three different environments. The non-significant genotype x environment (linear) and significant pooled deviation for shelling percentage, 100-seed weight and yield per plot suggested a greater importance of non-linear component of g X e interactions. On the basis of stability parameters, two varieties, namely, VL-3 and KS-136 were found high yielders and suitable for unfavourable environments. Further, these two varieties have non-significant deviation in almost all the attributes. Although the varieties, Sel-82 and KS-195 are high yielder, their @values were more than unity with higher S2 CIT values. Hence, these two varieties are suitable for favourable environments only.
