Genotype x environment interactions for seed yield and its components in sesame (Sesamum indicum L.)

A study was conducted to analyze the genotype by environment (GxE) interaction effect on yield and its components in sesame grown in three environments by using AMMI analysis. The mean square were significant for genotypes, environments, GxE interaction for the characters viz., number of capsules, 1000 seed weight and single plant yield. The genotypes namely PSR 2007 x Co1, Si 42 x Co 1, Si 42 x VRI 1, AHT 123 x VRI 1, B 203 x SVPR 1 and YLM 4030 x SVPR 1 recorded high mean but low interaction effect which are desirable for releasing as stable hybrids. The genotypes OMT 30 x VRI 1, OMT 30 x SVPR 1 and DPI 1424 x VRI 1 exhibited high interaction effect and are suitable for specific environments.
