Abstract:
The present investigation was conducted to study stability of 13 genotype of broccoli for growth and yield traits. The analysis of variance for stability showed that mean squares due to environment (linear) components revealed significant difference among the genotypes for all the traits studied indicating that variability among environments was large enough for a proper estimation of 'bi' values. The significance of mean squares due to genotype x environment (linear) components was noticed for plant height, curd length, curd weight/plant and curd yield. Among the genotypes used in the study, Green Magic exhibited highest curd yield and was found to be stable over the different environments, which could be used in the breeding programme for the development of high yielding stable broccoli genotypes over environments for future use.
