摘　　要：以22份对炭疽病有一定抗性的亚麻种质资源为试验材料,进行室内和田间抗炭疽病的鉴定与筛选,并优化筛选抗性鉴定方法。结果表明,最佳抗性鉴定方法处理组合为:接种方法为喷雾接种法,接种孢子液浓度为3.5×106个·mL-1。综合室内和田间鉴定结果,认为γ0311、K6531和Viking是3份亚麻高抗材料,86045-17-13-8是感病材料,其他是抗病或中抗材料。该研究结果对培育亚麻抗炭疽病新品种、提高黑龙江省亚麻生产水平具有指导意义。Total 22 germplasm resources of flax resistant to anthracnose were identified and selected both in greenhouse and fields. The results showed that by optimizing the method for resistance to anthracnose, the spore suspension with concentration of 3.5× 106 spores-mL was chosen as the best treatment combination for resistance identification, the results on resistance identification of flax both in greenhouse and fields proved that y0311, K6531 and Viking were considered to be highly resistant materials; 86045-17-13-8 was seen as susceptable material and the others were thought to be resistant materials or middle resistant materials, which had instructional significance for breeding new flax cultivar resistant to anthracnose and improving the standard of flax production in Heilongjiang Province.
