摘要
玉米品系质量受多种性状共同影响,选择合适的分析方法利于开展品系评价,灰色关联度分析法能够将品系的产量同其他农艺性状综合在一起进行评价。研究利用灰色关联度分析法对35份玉米品系的10个重要性状进行了分析,用等权关联度及加权关联度同时计算,研究结果表明,品系LK731与参考品种的关联度最大,产量高、农艺性状等综合性状最好,品系LK718等产量低的同时其他性状表现也很差,若要应用大田生产,仍需进一步优化其性状。
The quality of maize strains was affected by many traits,and the suitable analysis method was favorable to the evaluationof strains. Gray correlation analysis could be used to evaluate the yield of the strains with other agronomic traits. 10 important traitsof 35 maize strains were analyzed by gray correlation degree analysis with simultaneous calculation of equivalence degree andweighted correlation degree. The results showed that the correlation degree between LK731 and the reference variety was thehighest,the yield of LK731 was high,its agronomic traits and other comprehensive characteristics were the best,strains such asLK718 had not only low yield but also poor other performance.If it were to be applied to field production,the traits would still needto be further optimized.
