甘蓝型单双低油菜花器性状与产量性状的相关性分析

Correlation analysis in flower morphology and yield composition in single low and double low rapeseed(Brassica napus)

田间考查３７个甘蓝型单、双低油菜品系的花器大小和产量性状，对其变异程度和相关系数作了分析。结果表明，不同品系间花器大小和产量性状差异较大，花器大小与角果长、每角粒数呈极显著正相关，与单株有效角果数呈显著或不显著负相关。

Taking 37 rapeseed varieties (Brassica napus L.) with low glucosinolate or low glucosinolate and erucic acid as field experimental materials, the flower morphology and yield composition were examined, and the variation and correlation coefficient among these characters were also analyed. The results showed that the flower morphology and yield composition varied greatly in different varieties. The flower morphology were significantly correlated with siliqua, but were inversely correlated to the siliqua number per plant either no or siginificant level.
