对引进的黄改系昌7-2、浚92-8和浚92-6主要的农艺性状进行配合力测定,为北方选育新品种提供依据。采用不完全双列杂交遗传交配设计,对昌7-2、浚92-6、浚92-8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,昌7-2主要经济性状GCA较高,表现较好,育种潜力较大。
The determination of combining ability of the introduced agronomic traits such as Chang 7-2, Jun 92-8 and Jun 92-6 in Huangshan was carried out to provide basis for breeding new varieties in northern China. The combining ability of chang 7-2, jun 92-6 and jun 92-8 was studied by using incomplete dialleaf genetic mating design. The results showed that there were significant or extremely significant differences among the GCA populations of most agronomic and economic traits. The main economic traits of Chang 7-2 had higher GCA, better performance and greater breeding potential.
