摘要: 对K305的7个诱变系和698-3的8个诱变系配合力分析发现,与对照相比,其多数性状的GCA效应表现出显著或极显著差异,同时不同诱变系杂交组合在不同性状上的SCA效应与对照也存在较大差异,其中部分诱变系组配的组合优于原对照组配的组合,说明诱变系有可能组配出更加优良的组合。研究还表明,诱变系与对照相比各具特点,尤其是698-3诱变系1227为具高产潜力的矮秆材料,应用时应注意根据育种目标选择利用。

Abstract: Compared with CK, the combining ability analysis results of the seven mutations of K305 and eight mutations of 698-3 indicated that the GCA effects of most characters had significant difference.In addition, there existed large difference in the SCA effects of different characters in hybrid combinations of mutation, and some combinations of mutants were better than the original combinations, which showed that more excellent combination mutants might be obtained.The results also indicated that the CK and mutations have respective characteristics, especially for the short plant height material 698-mutation 1227 with a potential high yield.So the application should based on the different breeding objective.
