摘要
田间调查表明,圆果种黄麻品种间抗炭疽病性存在明显差异。将莆田、南安、漳州、福州和广州等地不同品种上采集分离的30个菌株,用10个初选鉴别品种进行接种鉴定,根据反应型可以分为3个类群19个致病力不同的菌系,证实黄麻炭疽病菌存在生理分化现象。本省以致病力较强的第二类为主,发生频率最高;其次是致病力最强的第一类群。黄麻抗病育种宜针对第一致病类群进行,同时不断开拓利用新的抗源。
The natural resistance of varietal resources had been investigated in 1986 and 1987. The results showed that there were significant differences of resistance among varieties of Corchorus capsularis. Thirty isolates of C. corchori were collected from affected jute plans in different jute growing areas-Putian, Nanan, Longhai, Fuzhou and Guangzhou. Three pathogenic groups were determined aocording to the disease reactions on ten prelimimary differential varieties, indicating the physiological specialization of C.corchori. Jute breeding for an-thracnose resistance should be primary aimed against pathogenic group No.1 which was found most virulent, and attentions sholud also be paid to developing new disease-resistant parents.
