摘要
Abstract
[ Objective] The yield of summer maize and correlation degree of agronomic traits in Huaibei region were studied. [ Method] Based on the grey relational analysis method,the relationship between the yield of 14 summer maize lines( varieties) and 10 main agronomic traits and the correlation between the traits were studied. [Result] The yield of 76. 9% lines was significantly higher than that of control Zhengdan 958. The correlation degree order of main agronomic traits and yield was as follows:bare top length,plant height,ear row number,ear length,row grains,ear height,100-seed weight,lodging and stem broken rates,seed-producing percentage,ear diameter. [ Conclusion] In the breeding prac-tice, we should choose the long lines of the bald tip shorter,plant height higher,ear rows more.关键词
