研究表明,油菜菌核病的发生程度与花瓣面积大小、花瓣在花序上残留时间的长短以及开花期天数等成正相关。与花瓣相关的这些性状对选育抗(耐)菌核病油菜新品种有一定参考价值。
The results showed that the occurrence of sclerotinia sclerotiorum was positively related to the area of petal, the length of petal on the inflorescence and the days of flowering. These traits associated with petals have some reference value for breeding new varieties of rapeseed resistant to Sclerotinia sclerotiorum.
