满足国内消费者对大豆及豆制品的需求，缩小我国大豆的产需缺口，培育并推广具有丰产性、广适性和抗病性等特点的大豆品种已成为大豆育种的重中之重。陇豆6号是由甘肃省农业科学院作物研究所以中黄12作母本、邯豆3号作父本，经有性杂交选育而成的大豆新品种。2022 — 2023年参加甘肃省大豆区域试验，折合平均产量3 419.9 kg/hm2，较对照品种增产。2023年参加甘肃省生产试验，折合平均产量3 196.4 kg/hm2，较对照品种陇豆2号增产10.1%。该品种籽粒含粗蛋白达459.7 g/kg、粗脂肪205.4 g/kg。陇豆6号丰产性好，适应性强，抗倒伏，田间长势和落叶性较好，属于高蛋白品种，抗花叶病毒病、中抗灰斑病，适宜在甘肃省大豆中晚熟及晚熟品种类型区种植。

To meet the domestic demand for soybeans and soybean products and to reduce the supply-demand gap for soybeans in China, breeding and promoting soybean varieties with high yield, broad adaptability, and disease resistance has become a top priority in soybean breeding. Longdou 6 is a new soybean variety bred by the Crop Research Institute, Gansu Academy of Agricultural Sciences through the sexual hybridization with the female parent Zhonghuang 12 and the male parent Handou 3. In the 2022 to 2023 Gansu soybean regional experiment, Longdou 6 achieved an average yield of 3 419.9 kg/ha, which was higher than that of the control variety. In the 2023 Gansu production experiemtn, the average yield was 3 196.4 kg/ha, which was 10.1% higher than that of the control variety Longdou 2. The crude protein content of the seeds is 459.7 g/kg and the ether extract content is 205.4 g/kg. Longdou 6 has good yield, strong adaptability, resistance to lodging, good field growth and defoliation, and is a high-protein variety. It is resistant to Mosaic virus disease and medium resistance to gray spot disease, which is suitable for planting in the middle-late maturing and late maturing soybean varieties type area in Gansu Province.
