摘要
为分析近年北方春大豆区域试验参试品种(系)抗病性水平的演化,为大豆生产提供更好的育种思路和抗性育种材料,本研究利用中国北方春大豆种植区主要流行的SMVⅠ、SMVⅢ株系和大豆灰斑病菌1号、7号混合生理小种进行人工接种,鉴定评价2016—2019年参加北方春大豆品种区域试验不同生育期组品种(系)对流行病害的抗性。结果表明:5年间对SMVⅠ和SMVⅢ两个株系均表现为抗病的材料占总参试品种(系)的10.7%,对大豆灰斑病表现为抗病以上水平的材料占总参试品种(系)的43.3%。吉育256对SMVⅠ株系抗性最好,黑农504和吉农84对SMVⅢ株系抗性最好,吉育215,交大17号和绥农53对大豆灰斑病抗性最好。各生育期组别参试品种(系)对SMVⅠ的抗性水平主要集中在中抗和中感水平,对SMVⅢ的抗性水平主要集中在中抗、中感和感病水平,对大豆灰斑病的抗性水平主要集中在抗和中抗水平。除早熟组外,其他生育期组材料对SMV的病情指数没有随年份变化出现明显上升或下降趋势,早熟组参试品种(系)对流行SMV株系抗性逐年减弱。随生育期的缩短,参试品种(系)对SMVⅠ和SMVⅢ株系抗性水平提高、病情指数呈下降趋势;超早熟、极早熟、早熟和中早熟组材料对大豆灰斑病抗性没有随年份显著变化,且各熟期组之间抗性加权值无显著性差异。各省份或地区材料对SMVⅢ株系的病情指数均值高于SMVⅠ株系;辽宁参试品种(系)对SMV抗病性最佳;各省份或地区参试品种(系)对大豆灰斑病的加权值无显著性差异。
To analyze the evolution of disease resistance level of northern spring soybean cultivars in regional testing in recent years, SMVⅠ, SMV Ⅲ, physiological race No.1 and No.7 for soybean frogeye leaf spot, the mainly popular resistant bacteria strains in north China area were used in this study. The north spring soybean varieties in regional testing in 2016-2019 were evaluated by artificial inoculation to provide better breeding ideas and resistant breeding materials for soybean production. The results showed that disease resistance(R) varieties to both SMVⅠand SMV Ⅲ strains accounted for 10.7% of the total testing varieties in the five years, soybean varieties showed the above resistance(R) level to soybean grey spot accounted for 43.3% of the total testing varieties. The resistance of Jiyu 256 to the SMVⅠstrain, and the resistance of Heinong 504 and Jinong 84 to SMV Ⅲ strain were the best. Their resistance levels of cultivars tested to SMVⅠwere mainly concentrated in the medium-resistant(MR) and medium-sense(MS), to SMV Ⅲ were mainly concentrated in the medium-resistant(MR),medium-sense(MS) and sense(S) level,and to soybean frogeye leaf spot were mainly concentrated in resistant(R) and medium-resistant(MR) level in each maturity group. With the exception of the early maturity group, the disease index of cultivars in the other maturity group showed no obvious trend of increasing or decreasing with the change of years, and the resistance of the cultivars tested in the early maturity group to the popular SMV strain decreased year by year. Along the shortening of growth period, the resistance levels in tested cultivars to SMVⅠand SMV Ⅲ strain increased, the disease index declined. There was no significant change in the resistance of the varieties(lines) in super-early, medium-early, early and medium-early groups with years, and there was no significant difference in the weighted value of the resistance to frogeye leaf spot among the ripening groups. The disease index mean of cultivars bred in each province or region to SMV Ⅲ strain was higher than to SMVⅠstrain. The cultivars bred in Liaoning province had the best disease resistance. There was no significant difference in the weighted value for soybean frogeye leaf spot of soybean cultivars in different provinces or regions.
