摘 要: 本文对湖北省几个主要板栗品种对桃蛀螟的抗性进行了连续五年的调查。结果发现不同板栗品种对桃蛀螟的抗性存在明显的差异,以晚熟油栗型品种对桃蛀螟的抗性最强,而板栗品种对桃蛀螟的抗性与其总苞的形态结构没有明星相关性。 Resistance of several cultivars of Chinese chestnut to Dichoctosis punctifera was researched in successive five years. The results show that different cultivars have obvious different resistance, and late maturing cultivar has the strongest resistance. Cultivars have no clear relation to resistance and the shape and structure of bud.
