- 摘要:
- 为了客观反映大豆种质资源对菌核病的抗病水平，排除环境、土壤、年份、生态区和接种方法等因素的影响，采用相对抗病指数作为抗病指标，于2011年在黑龙江省农业科学院佳木斯分院的盆栽场及病圃内进行了大豆种质资源抗菌核病的鉴定。结果表明：筛选出抗病品种2份，占试验材料的3.2%；中抗品种1份占所鉴定材料的1.61%，低抗品种29份占所鉴定材料的46.77%，低感品种20份占所鉴定材料的32.26%，中感品种6份占所鉴定材料9.68%，高感品种4份占所鉴定材料的6.45%。试验结果为大豆菌核病抗原大规模准确筛选奠定了基础。
- Abstract:
- In order to objectively reflect the resistance of Sclerotinia sclerotiorum soybean germplasm,excluding the influence of environment,soil,years,regions,inoculation methods and other factors,the resistance of Sclerotinia sclerotiorum was identified in the pot farm and nursery in Jiamusi branch of Heilongjiang academy of agricultrual sciences in 2011.The results showed that：2 high-resistant varieties were screend out accounting for 3.2% of the test materials.1 moderately resistant varieties accounted for 1.61% of the identified materials.29 low-resistant varieties accounted for 46.77%,20 low-susceptible varieties accounted for 32.26%,6 susceptible varieties accounted for 9.68%,4 high-susceptible varieties accounted for 6.45% of the identified materials.The results laid a foundation for resistance screen of soybean Sclerotinia sclerotiorum.
