4个新选育玉米自交系的配合力分析

Analysis of Combining Ability of Four New Maize Self - bred Lines

采用不完全双列杂交方法,对新育的4个玉米自交系的8个主要农艺性状进行了配合力分析,据此分析参试亲本遗传特点及新育自交系的优缺点,为自交系选育和杂交种组配提供依据,并筛选出了一个配合力高的自交系。

The combining ability of 8 main agronomic characters derivel from partial diallel cross were studied for 4 new maize self - bred lines. The heredity of all parental characters, the advantage and disadvantage of new selected self - bred lines were analysed on these, scientific basis was provided for selecting self -bred line and hybrid combination. Moreover, one self- bred line with higher combining ability was selected .
