摘　　要：利用区域试验资料 ,采用回归和通径分析方法对杂交油菜品种黔油 11号产量及构成因素进行了分析。结果表明 :各因素对黔油 11号产量的贡献大小为单株生产力 >单株角果数 >分枝部位 >千粒重 >分枝数 >角实粒数 >株高 ;并建立了产量与各构成因素间的多元线性回归模型 y=2 6 1.15 - 1.2 2 x1 +0 .89x2 -2 1.5 1x3+0 .2 2 x4 - 3.85 x5+10 .4 0 x6 +8.72 x7。运用产量主效应值、离回归系数和回归离差分析表明 :黔油 11号具有较好的丰产性和稳产性 。Yield component factors of Qianyou 11, a new hybrid rape cultivar, were analyzed by using the method of regression and passage analysis based on the data of regional test. The result showed that the order of each factor contribution to yield of Qianyou 11 was: yield of each plant> pods of each plant> branches position> 1000 GW> branches number> grains of per pod> plant height. And the regression function between yield and yield component factors were: y= 261.15 - 1.22x 1 + 0.89x 2 - 21.51x 3 + 0.22x 4 - 3.85x 5 +10.40x 6+8.72x 7. According to the analysis results of major effective value, deviation regression coefficient and regression deviation error, Qianyou 11 possesses high yield stability, and suitable to be popularized in the most regions of Guizhou province.
