| Abstract: | Two Chinese silkworm strains Tai and Feng and two Japanese silkworm stralns Xiao and Hui were bred through hybridization and selection in different seasons. All of them have high resistance and are uniform in hatching, molting, exuviating and mataring. Based on the theory of heterotic vigor, a new silkworm variety Taifeng × Xiaohui was prepared. Compared to the control variety Jingsong × Haoyue, the new variety has a 6% increase in cocoon output, a 6% ~ 9% increase in production value, 1400 metres in silk length of one cocoon, 77% of reelabitity, 95 marks of neatness. Additionally, it is easier to produce eggs of this variety. Therefore, it is a preferable silkworm variety. |
