| 摘 要： | 运用种子腐烂率测试法对208份大豆材料进行测试,研究了根腐病原菌中立枯丝核菌对大豆的致病性,并对抗大豆立枯丝核菌抗源材料进行筛选。结果表明:立枯丝核菌是大豆根腐病病原菌中致病性较强的一种,大部分品种对立枯丝核菌高度感病,高感品种(系)153个,占参试材料的73.55%;高抗品种(系)21个,占参试品种(系)的10.1%,其中有7个来自国外;中抗品种(系)34个,占参试品种(系)的16.35%,其中12个中抗材料为创新改良的稳定品系。

| Abstract: | Rhizoctonia solani is a plant pathogenic fungus that can cause root rot of soybean.The resistance of 208 soybean germplasm to Rhizoctonia solani were measured by testing seed rot rate.Among the testd soybeans,153 accessions,accounting for 73.55% of total,were highly sensitive to Rhizoctonia solani;21 accessions,accounting for 10.1% of total,showed high resistance,and 7 cultivars of which came from abroad;34 accessions,accounting for 10.1% of total,showed medium resistance,and 12 of which came from modified stable lines.Results suggest there is short of soybean varieties resistant to Rhizoctonia solani,and much attention should be paid to soybean Rhizoctonia solani resistant breeding. |
