Analysis of genetic divergence of classification of morphological and larval gain characteristics of peanut cocoon silkworm (Bombyx mori L.) germplasm.

Abstract

A hierarchical agglomerative clustering analysis was undertaken for grouping the 51 lines silkworm, Bombyx mori L., based on larval gains parameters in the clustering process. The analysis was based on data from one rearing seasons with all 51 peanut cocoon strains of silkworm and varying morphological development potentials. The results indicate that two clusters can be realized based on larval development parameters. Further sub-grouping under these groups highlights genetically differences associated with the differentiation of various groups of lines as well as their significance for silkworm breeding. Estimates of all variables were further subjected to quick clustering and the results showed that both clusters constituted by three sub groups.
