高产春大豆新品种桂春豆1号的选育与评价

Breeding and Evaluation of New Spring Soybean Variety Guichundou 1 with High Yield

桂春豆1号是以桂春1号(靖西早黄豆×吉三选三)为母本,桂199(拉城黄豆系选)为父本有性杂交育成的春大豆新品种,该品种区域试验平均产量2631.60kg/hm2,较对照品种柳豆1号增产15.13%,生产试验平均产量2607.00kg/hm2,较对照品种柳豆1号增产14.64%,蛋白质含量39.91%,油分含量19.46%,抗SC11和SC13,耐酸铝能力较强,2006年通过国家农作物品种审定委员会审定。报导了桂春豆1号的选育与试验结果,并对关键育种技术进行了分析。

New spring soybean variety Guichundou 1 was bred through sexual hybridization, the male parent was Guichun l（Qinxizao soybean x Jisanxuansan）, and the female parent was Gui 1 99（Lacheng soybean inbreeding）. The mean yield of Guichundou 1 in the regional test was 2631.60kg/hm2, increasing by 15.13% as compare to the check variety Liudou 1. and mean yield in the production test was 2607.00kg/hm2, increasing by 14.46% as compare to the check variety Liudou 1.The protein content of this variety was 39.91%, and the oil content was 19.46%. This variety resisted to SCll and SC13, and showed strong tolerance to acid-aluminum. It has been examined and certified by the National Crops Varieties Approval Com- mittee in 2006. This paper reported the results of breed selection and experiment of Guichundoul, and ana- lyzed the key of breeding technique.
