摘要
利用361个东北大豆优异亲本材料,在辽宁、吉林、黑龙江三省8个点进行试验。在2013年自然湿涝条件下,通过分析品种在各试验点的苗情、生育期和产量差异,对参试品种进行耐涝筛选,将其分为强耐涝、耐涝、中耐涝和弱耐涝4种类型。描述了强耐涝优异品种的特征特性,为大豆耐涝育种提供亲本材料。
Three hundred and sixty-one elite spring Liaoning, Jilin and Heilongjiang province under the soybean parent materials were planted at 8 locations in natural waterlogging conditions in 2013. Based on the performance of seedling growth, growth period and yield differences at each location, the waterlogging tolerance of soybean varieties was divided into 4 types： strong waterlogging tolerance, waterlogging tolerance, medium-waterlogging tolerance and less waterlogging tolerance. The characteristics of strong waterlogging tolerance varieties provide references in selecting excellent parental materials for soybean waterlogging tolerance breeding. Key words： Soybean; Waterlogging tolerance; Screening; Germplasm resource; Material platform
