节水高产冬小麦新品种衡4399的选育及思考

摘要

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。2007~2008年参加河北省冀中南水地组区域试验，2 a平均产量为8206.35 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7868.4 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10574.7 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。%The winter wheat variety Heng4399 was bred by Dryland Farming Institute of Hebei Academy of Agriculture and Forestry Sciences.During the process, there are many advancing methods has been used,including the method of alternation selection in waterland and dryland,the method of appraisement in other lands,etc.. Heng4399 has the characters of high yield,water saving and very good resistances. Its DRI (Drought Resistance Index) is 1.152 as the first level drought resistance varieties.In water land group regional trail and production test of the south-center in Hebei Province in 2007 and 2008, the yield were 8 206.35 kg/hm2 and 7 868.4 kg/hm2, exceeded the CK by 6.93% and 7.81%, respectively. In 2011, Science and Technology Department of Hebei Province organized experts to harvesting and weighing in field,the yield was 10 574.7 kg/hm2,refresh the highest yields in Hebei Province. It is a very good variety for the Northern Huanghuai wheat area.This variety is ideal for treatment of groundwater over-exploitation . It is approved by Hebei Crop Variety Approval Committee in 2008. In 2014, it is one of selected varieties in the project, winter wheat spring irrigation water saving and stable yield and matching technology project of Hebei Province.
