| 摘 要： | 春用多丝量新蚕品种春蕾×明珠是经1980-1981年全国蚕品种鉴定通过,并由农业部指定推广的品种;具有体质强健、茧层率高、茧丝质优良等特点.在湖北省农村推广过程中比老品种东6×华合的张种产值高,茧丝质优良.但是本单交种属中等茧形的品种,全茧量不及老两种..又克蚁制种量稍低.为此进一步研究多元杂种的选配,先后配制了(春蕾A·改)×(明珠A·c)双交种和(791·春蕾)×(792·明珠)4元种,最后经实验室交杂鉴定和农村生产试验,选中了(春蕾·苏春)×(明珠·镇丰)这个优良的4元杂种组合.这对新品种组合具有张产茧量和张产值高.茧丝质全面优良的特点.受到农村,丝广普遍欢迎.同时交杂原种的克蚁制种量高,为制种场增加经济收益,因此这对4元杂种已成为湖北省当家品种,全面普及.

| Abstract: | The F1 hybrid race(Chun Lei × Ming Zhu)was identified aad certified by National Race Investigation Committee in 1982. This type of race had some advantages, such as strong physique, high cocoon shell percentage and good cocoon filament quality. During popularizing in the countryside in Hubei Province, the double hybrid race appeared better than the commercial one in income of cocoon crop and cocoon of filament quality, but the cocoon shape was medium, the cocoon yield per case of eggs and multiplication efficiency were lover than (791·CL) (792·MZ), and (CL)×(ZZ)was selected eventualy after some laboratory experiment and field tests. This type of race had high amount and income of cocoon crop, the economical character and multiplication efficiency were very good,and nowadays it become dominant one spread in Hubei Province. |
