摘要
利用不完全双列杂交法,对新育成的红菜薹胞质雄性不育系Eru-3、Eru-5和16个父本材料配制的32个杂交组合进行主要矿质元素Ca、Mg、Fe、Zn的配合力和遗传力分析。结果表明:雄性不育系Eru-5和父本D、E、F和H的一般配合力较高,是提高杂种一代矿质元素含量的理想亲本;组合Eru-5×G、Eru-5×H和Eru-3×L具有较好的特殊配合力效应,是矿质营养价值较高的优良杂交组合。遗传力分析表明:Ca主要受基因加性效应控制,Mg、Zn的遗传由加性和非加性基因效应共同控制,Fe主要由非加性基因效应控制。
The combining ability and genetic parameters were estimated for four major mineral elements(Ca,Mg,Fe and Zn) in F1 progenies of 32 crossing combinations of purple Cai-tai with the incomplete diallel cross using 2 novel male sterile lines as female parents and 16 inbreed lines as male parents. The results showed that male sterile line Eru-5 and male parents D,E, F and H,which had high GCA on Ca,Mg, Fe and Zn, could be regarded as good parents. The combinations Eru-5 X G, Eru-5 X H and Eru-3 X L had high SCA on Ca,Mg,Fe and Zn. The analysis of heritability revealed that the heredity of Ca was mainly controlled by additive effect; those of Mg and Zn were mainly controlled by additive and non-additive effects; and the heredity of Fe was mainly controlled by non-additive effects.
