Analysis of phenotypic stability for yield and yield components in bivoltine silkworm hybrids

K Mandal, SM Moorthy

Stability analysis was carried out to study stability in performance and genotype X environment interactions for 42 bivoltine silkworm hybrids reared in three seasons for three years. Stability statistics based on Eberhart and Russell approach were estimated for all the hybrids and traits. The G X E (linear) interaction was highly significant for all characters except shell%, when tested against pooled deviation, which revealed that there are wide genetic differences among hybrids for their regression on the environmental index. Considering high mean value and regression coefficient for most of the yield and yield components SK3 x BHR2 and O3 x D6 (P) found to be stable hybrids. Remaining hybrids seemed to be considerably influenced by Genotype X environment interactions and may be recommended for particular seasons.
