“…Heterosis is observed when silkworms of different genetic backgrounds are mated (Talebi et al, 2010). Recent studies showed that the efficiency of heterosis for improvement of the cocoon and silk characters in the hybrids will be more efficient than the inter-line selections (Seshagiri et al, 2009). In several countries, many studies on genetic divergence in bivoltine and multivoltine silkworm pure lines were carried out to determine the magnitude of genetic diversity among lines and to assess the importance of quantitative characters by using Line × Tester test (Ramesha et al, 2009).…”

This study was carried out to identify parents and hybrids by determination of general combining ability (GCA), specific combining ability (SCA), and heterosis in pure lines and their hybrids, which were selected from our gene sources, to determine new hybrid combinations that could be alternative or higher in yielding compared with M × N hybrid used in production. Combining ability and heterosis effects were studied for the eight quantitative characters through line × tester mating design. Chinese origin lines (KZ, ZF) were identified as females and Japanese origin lines (BR, ZB) as males, and by these, four hybrids were derived. M, N, and their hybrid were both used as control genotypes and to calculate the heterosis and commercial heterosis as well. All the genotypes were reared in standard conditions, in three replications. ZF (for pupa survival rate) and ZB (for hatching and filament length) presented significantly higher and positive GCA effects. In addition, ZB had negative GCA effect for infertile egg rate. Effects of SCA were not significant for all the characters. In conclusion, ZF × ZB hybrid could have a potential for the higher cocoon and silk production in Turkey.
