“1138—2”是原南京农学院于1962年从地方品种“奉贤穗稻黄”中经单株选育而成的。1973年参加长江流域四川、湖北、湖南、安徽、江苏5省夏大豆品种区域试验,绝大部分试验点表现增产。1974年、1975年试验结果基本与1973年一致。据1975年四川省绵阳地区农科所试验,亩产315.3斤,比对照“猴子毛”增产20.4%;湖北省钟祥县农科所试种,亩产373.5斤,比对照“猴子毛”增产10.9%。株型紧凑,分枝粗短,收敛。有限结荚习性。紫花。茎秆直立,开花期下部茎秆呈6棱,棱角明显。叶片中等大小,小叶尖直向上略呈梭标状,叶色黄绿。荚草黄色,中 “1138-2” is a former Nanjing College of Agriculture in 1962 from the local variety “Fengxian spike rice yellow” by the single plant breeding. Participated in the Yangtze River Basin in Sichuan, Hubei, Hunan, Anhui, Jiangsu, five provinces in summer soybean varieties regional trials, the vast majority of pilot sites show yield. In 1974 and 1975, the test results were basically the same as in 1973. According to the experiment conducted by the Agricultural Science Institute in Mianyang, Sichuan Province in 1975, the yield per mu was 315.3 kg, an increase of 20.4% over the control “monkey hair”; the trial of Zhongxiang Agricultural Science Institute in Hubei Province took 373.5 kg per mu, an increase of 10.9 %. Plant compact, short branches, convergence. Limited pod habit. Purple flowers. Stems erect, lower flowering stem was 6 edges, edges and corners obvious.
