| 摘 要： | 以12份引进美国解禁玉米自交系为供试材料,4份课题组骨干玉米自交系(KA105、KA064、KB043和KB204)为测验种,采用NC-II遗传交配设计,进行配合力测定与分析。结果表明,测验种KA105和KA064产量一般配合力(GCA)效应表现优良,供试美国玉米自交系中PHPR5、MBST、LH213、2FACC、LH212Ht、LH209和PHR47产量GCA效应表现优良。杂交组合PHPR5×KA105、LH213×KA105、PHH93×KA105、2FACC×KA064、LH212Ht×KA105、PHPR5×KB204产量的超标优势较强,可进一步试验。

| Abstract: | In this study, twelve declassified American maize inbred lines were used as test materials, and four research group core maize inbred lines(KA105, KA064, KB043 and KB204) were used as test species, using NC-II Genetic mating design for combining ability test and analysis. The results showed that the general combining abilities(GCA) of KA105 and KA064 were excellent, and the yield GCA effects of PHPR5, MBST, LH213, 2FACC, LH212Ht, LH209 and PHR47 in the US maize inbred lines were excellent. The hybrid combinations PHPR5×KA105, LH213×KA105, PHH93×KA105, 2FACC×KA064, LH212Ht×KA105, and PHPR5×KB204 had strong over-stand heterosis and could be further tested. |
