摘　　要：五星2号由河北省农林科学院粮油作物研究所大豆中心以冀豆9号为母本,Century-2为父本经有性杂交系谱法选育而成。2002~2003年区域试验平均产量3 183.23 kg·hm-2。SMV抗性鉴定结果表明：该品种对黄淮中北部流行株系SC3、SC8,黄淮南部（江苏）株系Sa均表现高抗,对东北流行株系N3表现免疫,此外,对近期发现的重组型SMV分离物3238表现高抗。该品种因脂氧酶2缺失具有无豆腥味特性,蛋白质含量37.18%,脂肪含量23.97%,属于高油品种。Wuxing 2,derived from Jidou 9 × Century-2,was selected by Soybean Center of Cereal ＆ Oil Crops Institute,Hebei Academy of Agricultural and Forestry Sciences.The yield of Wuxing 2 was 3 183.23 kg·ha-1in regional trials during 2002-2003.SMV resistant identification showed that it was high resistant to Huang-huai north-center epidemic strains SC3,SC8,Huanghuai（Jiangsu） southern epidemic strain Sa,immune to north-east strain N3.It was also high resistant to recombinant SMV isolates 3238.It tastes no beany flavor because of lipoxygenase 2 missing,the protein content is 37.18%,fat content is23.97%.It belongs to high oil cultivar.
