摘要
选用9个玉米自交系,采用NCⅡ(不完全双列杂交)设计的原理和方法,对由此组配的20个杂交种进行配合力分析,并估算其遗传参数。结果表明,Mo17,P138,PHB1M,PH4CV是一般配合力(GCA)效应值表现优良的自交系;筛选出了综3×PHB1M,PH6WC×PHB1M,P138×PHB1M,PH6WC×郑58为高产组合;并得出百粒质量、出籽率、穗粗、每行粒数不宜早代选择,穗长可以进行早代选择。
9 maize inbred lines were selected in this paper, using the NC Ⅱ （incomplete diaUel cross ） design principle and method, the gener combining ability and genetic parameters of 20 hybrids equipped by 9 maize inbred lines were estimated. The results showed that Mo17, P138, PHBIM and PH4CV were the general combining ability effect value of excellent performance of inbred lines; Zong 3 ~ PHB1M, PH6WC × PHB1M, P138 × PHB1M, and PH6WC × Zheng 58 were high yield combinations. The agronomic traits of 100-ker- nels weight, shelling percentage, ear diameter and kernels per row should not be selected in early generation, while the ear length should be selected in early generation.
