| 摘 要： | 应用灰色关联度分析法对1998年辽宁省玉米新品种区域试验(晚熟A组)汇总结果进行分析表明,与产量关系最密切的性状是生育期、穗行数、株高和穗位高,其次是穗长、空秆率和倒伏率。在各经济性状中,穗行数与空秆率关系最为密切,其次是百粒重与空秆率、百粒重与穗长之间的关系;在各农艺性状中,株高与穗位高关系最为密切,其次是生育期与穗位高之间的关系;对玉米新品种农艺性状和抗病性状与经济性状分析表明,生育期与穗行数、丝黑穗病率与空秆率的关系最为密切。

Analysis of Grey Correlation Degree on Characteristics of New Maize Cultivar |
| |
| Abstract: | By the analysis of grey correlation degree on regional test of new maize cultivar(late A)in Liaoning in1998.It showed that growth and ear row number and plant height and ear height on plant were closely related with yield,then ear length and bare plant rate and lodging rate.Among eco nomic characters,the relationship between ear row number and bare plant rate was greatest,then the rela-tionship between100-grain weight and bare plant rate,between100-grain weight and ear length.A-mong agronomic characters,the relationship between plant height and ear height on plant was great-est,then the relationship between growth and ear height on plant.Analysis on new maize characters a-mong agronomy and disease resistance and economy,showed that growth was closely related with ear row num ber,the relationship between smut rate and bare plant rate was greater. |
