| 摘 要： | 配合力测定是柞蚕育种中选择优良亲本和组配优良杂交组合行之有效的方法之一。选用8821、8822、9906、抗大、黑翅和582共6个柞蚕品种为亲本,采用双列杂交(Griffing)方法分析了柞蚕产茧量、千粒茧质量及收蚁结茧率3个性状的配合力。结果表明:除千粒茧质量外,产茧量和收蚁结茧率的特殊配合力(SCA)方差显著地大于一般配合力(GCA)方差,说明在杂交后代这2个性状的非加性效应占主导地位,而千粒茧质量则以加性效应为主。供试亲本间及各组合间的GCA和SCA差异较大,其中亲本材料582的产茧量、千粒茧质量及收蚁结茧率3个性状均表现出最高的GCA效应值;杂交组合582×抗大的产茧量和收蚁结茧率的育种值与SCA之和明显地优于其他组合,千粒茧质量的育种值与SCA之和最优的组合为582×9906。

| Abstract: | Determination of combining ability was one effective way to select excellent parents and make excellent cross combinations in breeding of Antheraea pernyi.This study selected 6 tussah varieties including 8821,8822,9906,Kangda,Heichi and 582 as parental strains,and analyzed the combining ability of three traits,namely amount of cocoon crop,thousand-cocoon weight and cocooning rate to newly hatched larvae,by Griffing's diallel cross method.The result showed that the variance of special combining ability(SCA) ... |
