摘  要：
开展优质核不育两系杂交油菜早中熟新组合比较试验,结果表明:2种熟期类型杂交组合间产量差异明显,中熟组合单位面积产量极显著高于早熟组合,对比分析产量构成因子,主要是平均角粒数多和千粒重重,2种熟期类型组合间株高和一次分枝数差异较小,油菜菌核病感病程度中熟组合相对较轻。因此,油菜生产不可一味选择和使用早熟类型品种或组合,不然将较难获得理想产量和生产效益。

摘  要：
The comparison study on the combination of two lines hybrid rape of early and medium maturing variety with high-quality nucleus sterility was carried out. The results showed that the hybrid combination of the varieties with the same maturation period displayed significant difference in the yield,the yield of combination of the varieties with mid-maturation exhibited much higher yield per unit than that of early-maturation combination. Through the analysis of the yield components factor,the combination of the varieties with mid-maturation showed more seed number and larger thousand seed weight. However,the differences of the plant height and available primary branches between the two types of combination were smaller,the combination of middle-maturation varieties showed relatively light disease indexes of rape sclerotinia.So it was not right to blindly choose and use precocious type varieties or combinations,otherwise it was difficult to obtain ideal yield and production efficiency.
