摘要
采用完全双列杂交半轮配方法,分析了同源四倍体普通白菜茎芥菜胞质雄性不育系07P-2及5个四倍体普通白菜自交系配制的15个F1的16个农艺性状的配合力。结果表明:16个农艺性状的遗传均受基因加性效应、显性效应和互作效应的共同作用;07P-10农艺性状的一般配合力(GCA)最好,是综合性状优良的亲本,雄性不育系07P-2一般配合力次之,可作为四倍体普通白菜F1的制种骨干亲本;不同性状间及同一性状不同组合间特殊配合力(SCA)效应值差异较大,根据SCA综合表现,07P-2×07P-7、07P-2×07P-10具有较高的应用价值。
15 crossing combinations are made by 4xMtCMS and 5 parents of pakchoi〔Brassica campestris L.ssp.chinensis(L.)Makino var.communis Tsen et Lee〕with the method of complete diallel cross(half mating design).The result shows that 16 agronomical characters are controlled by the additive gene effect,dominance effect and interaction effect.And among 6 parents 07P-10 is a best parent,as it has highest general combining ability.It is excellent parent materials for the most of traits.The sterile lines 07P-2 is a better parent for quality genetic improvement research in autotetraploid pakchoi.The analysis of SCA effects show that the SCA effects of different characters in the same parent are obviously different,so does the same character in different parents.According to the comprehensive performance of the SCA effects,07P-2×07P-7 and 07P-2×07P-10 have application of great value because they include sterile lines 07P-2.
