摘要
以4255、169、4344、44、K10和龙抗11为测验种,对外引的14个矮秆玉米自交系,按NCII设计,对小区产量等性状进行了配合力分析和杂种优势分析。结果表明:矮01、矮1127、490和NY-1是综合表现比较理想的自交系,从其组配的组合中筛选到高产杂交组合的可能性较大,应当充分加以利用;其余各自交系各自有其突出的优良特点,可根据育种要求加以利用。
Taking 4255,169,434,444,K10 and Longkang 11 were used as test varieties,the combining ability analysis and heterosis analysis were carried out on 7 properties and the yield of treatment plot by NCⅡ design. The main results were as followed ：Dwarf-01 ,Dwarf-112,7490 and NY-1 were the ideal inbred lines of the 14 short stalk maize inbred lines, they should best use because because they had larger possibility of screening the combination to obtain the higher yield hybridize combination. The other inbred lines had their own prominent characteristics,and they should be made the best use according to the need of breeding.
