衡4399是河北省农林科学院旱作农业研究所采用水旱交替选择法、异地鉴定法等先进方法选育的冬小麦新品种。其高抗条锈、叶锈和白粉病,中抗赤霉病,抗热、抗寒性强;具有节水、高产的突出特点,抗旱指数1.152,为员级抗旱品种。2007耀2008年参加河北省冀中南水地组区域试验,2 a平均产量为8 206.35 kg/hm2,较对照品种石4185增产6.93%;2008年参加河北省冀中南水地组大区生产试验,平均产量为7 868.4 kg/hm2,较对照石4185增产7.81%,居参试品种第1位;2011年河北省科学技术厅组织专家在高产高效创建示范方麦田实打实收,产量为10 574.7 kg/hm2,刷新了河北省冬小麦单产最高纪录,是非常适合黄淮北片冬麦区种植的一个优良品种。2008年通过河北省品种审定委员会审定(审定编号:冀审麦2008002号)。该品种是治理地下水超采的理想品种,2014年被列入河北省冬小麦春灌节水稳产配套技术项目入选品种。 Heng 4399 is a new winter wheat variety selected by advanced methods such as Alternate Selection of Flood and Drought, Alternative Identification and other methods in the Institute of Dry Farming, Hebei Academy of Agriculture and Forestry Sciences. Its high resistance to stripe rust, leaf rust and powdery mildew, resistance to scab, heat, cold and strong; with water-saving, high-yielding prominent features, drought resistance index 1.152, for the class drought-resistant varieties. 2007 Yao participated in the regional experiment of Jizhong Nan Shui Land Group in Hebei Province in 2008 with an average yield of 8 206.35 kg / hm2 for 2 years, an increase of 6.93% over that of the reference variety Shi 4185. In 2008, it participated in the production trial of the Jizhong South Shuidi Group in Hebei Province, The average output was 7868.4 kg / hm2, which was 7.81% higher than that of the reference stone 4185, ranking No.1 in the tested varieties. In 2011, Hebei Provincial Science and Technology Agency organized experts to establish a demonstration farm in high yield and high efficiency, with a yield of 10 574.7 kg / hm2, refreshing the highest winter wheat yield in Hebei Province, is a very suitable winter planting Huanghuaibei a fine varieties. In 2008 through the Hebei Provincial Examination and Approval Committee (validation number: Jibei Mai 2008002). The variety is ideal for over-exploitation of groundwater. In 2014, it was included in selected varieties of winter irrigation and water-saving and steady-yielding production of winter wheat in Hebei Province.
