Abstract

To identify the molecular markers associated with growth and yield parameters in silkworm, Bombyx mori, RAPD profiles generated with seven UBC primers for fourteen silkworm stocks, originated from China, Japan, India, and Russia, were statistically analyzed. Stepwise multiple regression analysis establishes significant association of 45 markers with larval span, growth indices and four cocoon yield parameters relevant for silk production and t-test attest significance of the association of 89.51500 bp and 54.13300 bp, respectively, with longer larval duration and high cocoon weight. The validity of this selection of markers was further supported with discriminant function analysis (DFA) done on the basis of Mahalanobis D 2 statistics. The two indices of yield/growth were also tested with DFA, which helped in identifying a few markers and thereby opened scope of using such marker (e.g., 91.11900 bp) for incorporating molecular markers in the breeding program for crop improvement in silkworm.
