Assessment stability and G x E interactions of baby corn hybrids for yield and yield contributing traits

Abstract

The present study consisted of total 45 hybrids along with 18 parents and 2 checks. These entries were evaluated in randomized block design with three replications over three locations. Observations were recorded on ten characters to study per se performance, estimates genotype × environment interaction and stability parameters. The crosses × environment interactions were significant for all the characters indicating existence of non-linear response of crosses to the changing environments. The analysis of variance for individual environment indicated significant differences among genotypes for all the traits indicating the heritable nature of inheritance of these traits. The crosses EIQ-103 × EI-2156, EIQ-180 × EI-2518-4, and EIQ-103 × EI-670-2 were found to perform well across different environmental conditions for yield and yield-contributing traits. Specifically, the crosses EIQ-103 × EI-2156 and EI-1104-1 × EI-2156 demonstrated stability across various environments, while the crosses EI-2173 × EI-2156 and EIQ-235 × EI-2518-4 were particularly suitable for unfavourable conditions.
