为了培育适宜在甘肃省中晚熟生态区种植的优良玉米新品种，甘肃禾盛种植农民专业合作社与甘肃省农业科学院作物研究所以自育系 NDSJ014为母本、自育系 NDSJ003为父本组配杂交组合，经多年试验鉴选，培育出了粮饲兼用型玉米优良杂交种禾盛209。在2018 — 2019 年甘肃省中晚熟水地A 组玉米区域试验中，2 a 12 点(次)平均折合产量为15 860.3 kg/hm2，较对照品种先玉335增产5.3%。该品种生育期141 d，活秆成熟。株高315 cm，穗长22.2 cm，穗粗5.2 cm，千粒重340.1 g。籽粒(干基)含粗蛋白79.2 g/kg、粗脂肪39.4 g/kg、粗淀粉 749.5 g/kg、赖氨酸 2.4 g/kg，容重777 g/L。适宜在甘肃省中晚熟生态区域种植。

In order to breed new maize varieties with high quality and are suitable to plant in ecological areas that are middle to late maturing ones in Gansu, Hesheng 209, an excellent grain-forage hybrid using self-selected line NDSJ014 as female parent and self-selected line NDSJ003 as male parent, was bred by Gansu Hesheng Professional Farmers' Cooperative of Planting and Institute of Crops of Gansu Academy of Agricultural Sciences. From 2018 to 2019, yield data from maize regional experiment of Gansu Province(mid-late maturity, irrigated land, group A), taken 12 sites(points) in 2 a, was 15 860.3 kg/ha, which showed an increase of 5.3% compared with that of the control cultivar Xianyu 335. The growth period was 141 days with green stem at maturity, the plant height was 315 cm, the ear length was 22.2 cm, the ear diameter was 5.2 cm and the 1000-grain weight was 340.1 g. Contents of crude protein, ether extract, crude starch and lysine in grain were 79.2 g/kg, 39.4 g/kg, 749.5 g/kg and 2.4 g/kg, respectively, and bulk density was 777 g/L. This cultivar is suitable to be grown in ecological area of middle and late maturity in Gansu Province.
