摘要
为解决黄淮南片小麦区域所面临的赤霉病和茎基腐病多发,以及叠加气候异常多变导致的冻害和后期高温逼熟现象,采取聚集优势资源,运用复合杂交、水旱异地系统选育的方法,经比较试验、区域试验、生产试验和大区适应性定位试验示范,于2022年通过河南省小麦新品种审定,实现育种目标.小麦新品种'鹤麦1707'具有高产稳产早熟多抗特性,品种选育采用复合杂交、多态鉴定等方法有利于优良基因聚合和适应性选择,品种持续改良能更好满足需求.
Abstract
To solve the frequent occurrence of scab and stalk rot in the southern Huanghuai wheat area,as well as the freezing injury caused by superimposed abnormal climate change and the phenomenon of ripening forced by high temperature in the later period,the superior resources were gathered,the methods of compound hybridization and flood and drought remote system breeding were adopted.A new wheat variety passed the approval in Henan Province in 2022 after demonstrations of comparative tests,regional tests,production tests,and large-scale adaptability tests,and met the breeding goals.The new wheat variety'Hemai 1707'has the characteristics of high yield,stable yield,early maturity,and multi-resistance,the variety breeding adopts methods such as compound hybridization,and polymorphic identification,which is conducive to the aggregation of excellent genes and adaptive selection.Continuous improvement of varieties can better meet the demands.
