【摘要】 利用一般配合力较高的玉米自交系作为杂交亲本,同时兼顾一般配合力与特殊配合力以便组配出强优势组合。组合172×137表现较好,有待进一步对其产量潜力和适应性进行多点、多年鉴定。172、K12、173、137是较理想的自交系。更多还原

【Abstract】 The results showed that the inbred lines which have higher GCA effect should be used as the parents of the combinations,GCA and SCA together must be given attention too,so that the combinations of strong heterosis were crossed.The combinations 172×137 was better than others,and must be tested for their yield potentiality and adaptation at many locations in many years.The maize inbred lines such as 172,K12,173,137,were ideal.更多还原
