摘　　要：为了解黄淮海地区大豆新品种(系)对大豆疫霉根腐病主要病原菌大豆疫霉的抗性情况,基于2020—2023年黄淮海大豆联合鉴定试验疫霉根腐病鉴定报告,分析报告中的568个大豆新品种(系)对5个代表性大豆疫霉菌株的抗性,并进行大豆种质抗病基因推导,统计地理分布情况。经过分析得出黄淮海夏大豆新品种(系)对5个大豆疫霉菌株的抗性比例呈逐年增加的趋势;2023年筛选出的抗4~5个菌株的大豆新品种(系)数量占比已高达55.43%。2020—2023年全抗5个菌株的新品种(系)有87个,占鉴定总数的15.32%,河南省的数量最多,占31.03%。剔除掉105个未进行抗病基因推导的大豆新品种(系),剩余的463个新品系对5个菌株共产生29种反应型,来源于北京的新品种(系)所含抗病反应类型最丰富,有25种;有284个新品种(系)产生的22种反应型尚无法推导出已知的抗病基因,推测可能含有新的抗病基因或抗病基因组合。本分析结果可为抗病品种得选育提供数据参考。The objective of this study is to understand the resistance status of new soybean varieties(lines)in the Huang-Huai-Hai area to Phytophthora sojae,the main pathogen of Phytophthora root rot of soybean.The study was based on the identification report of Phytophthora root rot in the Huang-Huai-Hai soybean joint identification test from 2020 to 2023.The resistance of 568 new soybean lines in the report to five representative P.sojae strains was analyzed.The disease resistance gene deduction of soybean germplasm was carried out,and the geographical distribution was counted.The analysis revealed a rising trend in the proportion of new summer soybean lines in the Huang-Huai-Hai region with resistance to five P.sojae strains year by year.The proportion of new soybean lines resistant to four to five representative P.sojae strains screened in 2023 had reached as high as 55.43%.From 2020 to 2023,87 new varieties and lines exhibited simultaneous resistance to all five P.sojae strains,accounting for 15.32%of the total identifications,with the largest number sourced from Henan Province,accounting for 31.03%.A total of 105 soybean varieties(lines)were excluded from further study due to unidentified resistance genes,leaving 463 new lines that exhibited a total of 29 reaction types to the five strains.The varieties from Beijing had the richest disease resistance reaction types,with 25 types.The 22 reaction types exhibited by 284 varieties(lines)could not be attributed to known disease resistance genes,suggesting the potential presence of new disease resistance genes or combinations.
