Abstract

                                Twenty nine promising genotypes of Indian mustard (Brassica juncea (L.) Czern & Coss) tested for their seed yield and phenotypic stability revealed that the genotypes interacted considerably with environmental conditions that prevailed in different situations. Both linear and non linear components were significant. S'd value was significant for 19 genotypes. Genotypes DIR 153 and RH 827, though having high s²d values, had almost unit responses to changes in environmental conditions and were high yielders. Genotypes RK 8302 and RK 8301 had high mean seed yield and indicated stable performance in high yielding environments. However, it was T 59 with high deviation value, which gave higher productivity in such situations. Genotypes RIK 81-1, RK 8304 and RS 83 performed promosingly in low yielding environments with latter two genotypes giving stable performance.
