在研究中我们对豫油一号的产量构成因素进行了回归和通径分析,同时分析了各性状间的简单相关和偏相关关系,以揭示它们之间真实联系的密切程度,为生产上提供参考。一、材料和方法利用1984～1986年河南省优质油菜区试三年16个点次的考种数据,在电子计算机上进行统计运算。多元回归分析中,偏回归系数通过逆矩阵求解,然后作显著性检验。性状间的偏相关系数利用简单相关系数求得。
In the study, we conducted regression and path analysis on the yield components of Yuyou-1, analyzed the simple correlations and partial correlations among the traits, in order to reveal the closeness of the true relationship between them and provide the production information reference. A, materials and methods 1984 ~ 1986 Henan Province, high-quality rape area test three years of 16 point test data, the statistical computing on the computer. In multivariate regression analysis, the partial regression coefficients are solved by an inverse matrix and then tested for significance. Partial correlation coefficients between traits were calculated using simple correlation coefficients.
