摘要
采用不完全双列杂交遗传交配设计,对6个玉米人工合成群体的配合力进行了研究。结果表明,多数农艺、经济性状的GCA群体间存在显著或极显著差异,少数经济性状的SCA在群体和测验种的组合间存在显著或极显著差异,群体P4、P2和P7主要经济性状GCA较高,优于对照高产组合出现次数较多,且群体P2和P7株高GCA表现较好,育种潜力较大。
The study analysed the combining ability through incomplete diallel cross design. The results showed that the GCA groups in most traits of agronomic and economic were significant or extremely significant difference among 6 synthetic populations. The SCA of many economic traits were detected that was significant or extremely significant difference between groups and test combinations. The results of GCA showed that most major economic traits of P4, P2 and P7 were higher. Some combinations were more than CK in yield and the traits of plant heights were better in P2 and P7, which were excellent in breeding potential.
