湖北省审定杂交油菜通径分析及决策系数计算
Hubei Province Authorized Hybrid Rapeseed Index of Path Analysis and Decision Coefficient Calculation
【摘要】 对通过审定的杂交油菜品种各考察指标对产量综合作用进行评估,用逐步回归分析法建立入选指标与产量的回归方程,并作通径分析及决策系数计算。由决策系数可知,为进一步提高产量,应延长生育期、提高芥酸含量、适度降低株高和病毒病病指。
【Abstract】 In order to assess the combined effects of the indexes to the production by an authorized hybrid rapeseed,the study used stepwise regression analysis selected indices and yield the regression equation to do path analysis and decision coefficient calculation.Known by the decision coefficient calculation,in order to further increase production,we should extend growth period and the erucic acid content,moderately reduce the plant height and viral disease index.
