摘　　要：为明确现有早熟大豆种质对大豆胞囊线虫病的耐病性,对中外350份种质资源进行大豆胞囊线虫病耐病性筛选鉴定。通过田间自然病圃法调查结果显示,参试大豆种质资源对大豆胞囊线虫耐病性存在一定的差异。其中未发现免疫品种,有3份大豆种质资源表现耐病,占参试材料的0.86%。耐病品种的产量构成因子在高SCN压力下高于无SCN压力,差异不显著;高抗病品种的产量构成因子在高SCN压力下低于无SCN压力,差异不显著;而感病品种的产量构成因子在高SCN压力下明显低于无SCN压力。3个耐病种质资源YJ002354、Nordia和郑196在胞囊数量调查中表现感病的情况下,其产量与高抗性品种差异不显著,明显高于感病品种。To clarify the tolerance of existing early maturing soybean germplasm to soybean cyst nematode,350 germplasm resources of China and foreign countries were screened and identified for soybean cyst nematode.The investigation results of the field natural nursery method showed that there was a certain difference in the tolerance of soybean germplasm resources to soybean cyst nematode.Among them,no immunized varieties were found,3 soybean germplasms were tolerant,accounting 0.86%of the total evaluated cultivars.The yield components of tolerance varieties were higher than those without SCN under high SCN pressure,the difference was not significant;The yield components of resistant varieties were lower than those without SCN under high SCN pressure,the difference was not significant;However,the yield components of susceptible varieties were lower than those without SCN under high SCN pressure.Three tolerance germplasms,YJ002354,Nordia and Zheng 196,showed no significant difference in yield from resistant varieties,but higher than that of susceptible varieties.
