摘　　要：为明确东北地区种质资源对大豆胞囊线虫3号生理小种(SCN3)抗性,以东北地区常用作亲本的620份大豆品种(系)为材料,经2020-2021年SCN3号生理小种田间病圃及室内盆栽接种鉴定。结果表明,2020年田间病圃鉴定对SCN3号生理小种表现中抗以上品种(系)有30份,抗病种质仅占鉴定种质总数的4.84%,2021年对这30份中抗以上材料进行室内盆栽接种鉴定,除白农9号、嫩丰15外,其余品种(系)抗性级别鉴定与田间病圃结果一致。其中农庆豆24、农庆豆28、齐农5号、丰豆1号等13个中抗以上品种可在大豆胞囊线虫病发区直接应用,MN0902CN、MN1701CN、中品03-5373、中品03-5297等9份抗病品系可用作种质资源创新抗病亲本,其他8份中抗品系可用作拓宽抗性基因遗传基础的复合杂交亲本。In order to clarify the resistance of germplasm resources in Northeast China to Soybean Cyst Nematode Race 3,620 soybean varieties(lines)commonly used as parents in Northeast China were used as materials.Through the field disease nursery and indoor potted inoculation identification of SCN race 3 from^(2)020 to 2021,the results showed that there were 30 varieties(lines)with medium resistance to SCN race 3 in the field disease nursery identification in 2020,and the disease resistant germplasm accounted for only 4.84%of the total identified germplasm.In 2021,30 medium resistant and above materials were inoculated and identified in indoor pot.Except for Bainong 9 and Nenfeng 15,the resistance level identification of other varieties(lines)was consistent with the results of field disease nursery.Among them,13 moderately resistant varieties such as Nongqingdou 24,Nongqingdou 28,Qinong 5 and Fengdou 1 can be directly applied in the incidence area of soybean cyst nematode,while 9 disease resistant lines such as MN0902CN,MN1701CN,Zhongpin 03-5373 and Zhongpin 03-5297 can be used as innovative disease resistant parents of germplasm resources,and other 8 moderately resistant lines can be used as compound hybrid parents to broaden the genetic basis of resistance genes.The results provided an application basis for the breeding of soybean cyst nematode resistance in Northeast China.
