通过玉米品种木挺和孚尔拉母本单交种自交选育二环系,对所选育的自交系进行配合力测定和各代农艺性状观察表明,所有的自交系配合力和农艺性状基本一致。将自交系配成单、三交种与引进的单,三交种进行产量比较试验,两者产量及农艺性状基本相同。为从理论上验证两个母本单交种的亲缘关系,对引进和自育的母本单交种进行同功酶测定,两者酶谱相同。通过以上分析,初步证明木挺、孚尔拉母本单交种亲本是由同一基本材料的不同系或姊妹系组成。
Through inbred lines of selfing Bombyx mandarina and Vulgamen, the determination of combining ability and agronomic traits in the selected inbred lines showed that the combining ability of all the inbred lines Agronomic basically the same. The inbred lines with single, three cross-species and the introduction of single and three cross-species yield comparison test, both yield and agronomic traits basically the same. In order to theoretically verify the genetic relationship between two maternal single crossbreds, the isozyme analysis of imported and self-bred maternal single crossbreds was carried out. Through the above analysis, initially proved that wood Ting, Fuerla maternal single cross parent is composed of the same basic materials of different lines or sister line.
