- 摘要:
- 为了充分利用玉米地方早熟群体及其选育的自交系，以自交系郑58、444、Mo17、改丹340为测验种，采用NCⅡ设计，对从地方早熟群体选育的12份自交系进行配合力及杂种优势分析。结果表明：选自同一群体的自交系配合力有较大差异，其中有3个自交系一般配合力较高；自交系9、7与Mo17特殊配合力较高、杂种优势较强。
- Abstract:
- In order to make full use of local maize inbred lines of early maturing group and its breeding,with inbred lines Zheng 58,444,Mo17 and Gaidan 340 were modified by NC II design,heterosis and combining ability of the place of early 12 inbred lines breeding were analyzed.The results showed that inbred lines selected from the same groups had greater differences in combining ability,there were three inbred lines with high general combining ability;inbred lines 9 and 7 had high special combining ability with Mo17,heterosis was strong.
