摘　　要：以 1 7个双低优质甘蓝型油菜品种 (系 )为材料 ,考察了主要经济性状及其与产量间的相关关系。结果表明 ,单株产量与一次有效分枝数、单株有效角果数及千粒重呈显著正相关 ;单株有效角果数与一、二次有效分枝数呈显著正相关 ,与角粒数呈极显著负相关 ;千粒重与一次有效分枝数呈极显著负相关 ,与二次有效分枝数、单株有效角果数呈显著负相关。The analysis with seventeen double low elite varieties of rapeseed indicated that yield per plant had a significant positive correlation with available primary branches,available pods per plant and thousand kernel weight.The same correlation was found between available pods per plant and available primary or secondary branches.The thousand kernel weight had a significant negative correlations with available primary branches,available secondary branches and available pods per plant.
