For success of any breeding programme, the selection of breeding resource material is of paramount importance. The selection of superior parents determines the degree of success of the breeding programme to a large extent. Therefore, it is highly pertinent to select and evaluate the suitable silkworm breeds before initiating any breeding programme. Accordingly in the present study eighteen silkworm breeds of diverse geographical origin were selected and evaluated with respect to eleven important yield attributing traits by employing multiple trait evaluation index (EI). Based on the overall evaluation index value only eight breeds viz., A209, CSR4, 61N, NB18, CSR2, N4D2 and SBNP-1 scored mean EI values greater than 50 whereas other ten breeds could not hold the promise. The short-listed breeds could be utilized as breeding resource material for the development of new breeds / hybrids.
