| 摘 要： | 为了解不同亚麻种质对派斯莫病的抗性差异,采用菌土接种法进行盆栽试验,统计分析各种质的发病情况并计算病情指数,对20个亚麻品种(系)进行派斯莫病抗性鉴定与评价。根据病情指数将20个亚麻品种(系)的派斯莫抗性分为抗病、中感、感病和高感。试验结果表明：不同品种（系）间存在明显的抗性差异,但整体抗性较差,无免疫品种（系）;有7个抗病品系,分别为H2012-1、ZY03001-2-4、Y0310-7-3、ZY03119-2-12、ZY06175-10-15、01059-1-6-2、9804-38,占供试种质总数的35%;中感、感病和高感品种(系)分别为9、2、2份,共占供试种质总数的65%,因此,H2012-1、ZY03001-2-4等7个抗性较强的品系可作为亚麻抗派斯莫病育种的材料。

| Abstract: | In order to understand the difference of disease resistance on pasmo between different flax germplasm, twenty varieties (lines) of flax (Linum usitatissimum L.) inoculated with infested soil of fungi in pots were cultured. The incidence and disease index of each germplasm were statistically analyzed. According to the disease index, the 20 flax varieties (lines) were divided into four groups: resistant, middle sensitive, sensitive and highly sensitive. The results showed that there were significant difference in resistance to pasmo among varieties (lines), and there were no immune varieties (lines) against pasmo in 20 tested flax varieties (lines). 7 flax lines (35% of total tested flax varieties (lines)) including H2012-1, ZY03001-2-4, Y0310-7-3, ZY03119-2-12, ZY06175-10-15, 01059-1-6-2 and 9804-38 were resistant to pasmo. The number of middle sensitive, sensitive and highly sensitive varieties (lines) were 9, 2 and 2, respectively. They accounted for 65% of total resources. Thus, H2012-1, ZY03001-2-4 and other five lines could be used as pasmo-resistant breeding for further study. |
