利用相关分析和灰色关联度分析法对蚕豆(Vicia faba L.)主要农艺性状进行了研究,探讨了蚕豆产量及主要农艺性状间的关系。结果表明,各性状与小区产量的关联度由大到小的顺序为单株产量(0.844 3)、单株荚数(0.835 6)、单株粒数(0.763 1)、株高(0.759 8)、百粒重(0.694 1)、荚长(0.652 5)、生育期(0.620 6);相关分析表明,小区产量与单株产量和单株荚数均呈极显著正相关,两种分析方法结果一致,因此,可以通过提高单株产量和单株荚数来提高蚕豆产量。
The main agronomic characters of Vicia faba L. were studied by correlation analysis and gray relational analysis, and the relationship between the yield and main agronomic characters of Vicia faba L. was discussed. The results showed that the order of correlation between the traits and community yield was single plant yield (0.844 3), pods per plant (0.835 6), grain number per plant (0.763 1), plant height (0.759 8) , Pearl weight (0.694 1), pod length (0.652 5) and growth period (0.620 6). Correlation analysis showed that the yield of plot was significantly and positively correlated with the yield per plant and the pods per plant. The results of the two methods Therefore, the yield of broad bean can be increased by increasing the yield per plant and the pods per plant.
