大豆新品种陇黄1号选育报告

Report on Breeding of New Soybean Cultivar Longhuang 1

大豆新品种陇黄1号从甘肃省农业科学院旱地农业研究所和农业生物技术国家重点实验室(香港中文大学)于2008年初从山西省农业科学院经作所引进的,以汾豆56为母本、汾豆62为父本常规杂交的F_3代群体中,经系谱法选育而成。陇黄1号2013—2014年参加甘肃省大豆品种区域试验,2 a 10点(次)平均产量2 442.00kg/hm^2,比对照陇豆2号平均增产3.75%;2015年参加甘肃省大豆品种生产试验,平均产量2 571.30 kg/hm^2,比对照陇豆2号增产9.04%。籽粒粗蛋白质含量39.40%,粗脂肪含量20.52%。其突出特点是抗病性强、稳产、商品性优且适宜间套作。该品种于2016年1月通过甘肃省农作物品种审定委员会审定,适宜在河西灌区、沿黄灌区、陇东旱塬区及等生态相似地区推广种植。

Longhuang1 is a new soybean cultivar,bred by Institute of Dryland Agriculture,Gansu Academy of Agricultural Sciences and School of Life Sciences, Chinese University of Hong Kong, by using pedigree breeding from F3 generation of combination of Fendou 62 as male parent and Fendou 56 as female parent which was introduced from Institute of Economic Crops,Shanxi Academy of Agricultural Science. In 2013 — 2014,the average yield of Longhuang 1 was 2 442.00 kg/hm^2,3.75% higher than the control Longdou 2 in Gansu Provincial Soybean Regional Test. In 2015,the average yield was 2 571.30 kg/hm^2,9.04% higher than the control Longdou 2 in Gansu Soybean Production Test. The crude protein content of grain is 39.40% and crude fat content is 20.52%. The cultivar has outstanding characteristics of strong disease resistance,stable yield,being excellent in quality and suiting for intercropping system. Been approved by Gansu Provincial Committee of Crop Variety Identification in January 2016,it is suitable to be grown in Hexi Irrigation Area,Yellow River Irrigation Area,Loess Plateau of East Gansu and other similar ecological regions.
