沧麦抗旱耐盐系列品种选育方法及系谱分析

摘要

针对环渤海地区土壤瘠薄盐碱、干旱缺水严重，自然灾害频发的生态特点以及小麦生产上急待解决的抗旱、耐盐、节水高产品种十分缺乏的问题，确定了以多抗（抗旱、耐盐、抗寒、抗干热风、抗病、抗倒伏）、节水、高产、稳产为育种目标，以丰富小麦品种遗传基础、提高品种产量潜力和抗逆水平为突破口，改进选种场圃设置，创新抗旱耐盐育种方法，育成了以抗旱耐盐碱丰产为主要特点的沧麦抗旱耐盐系列品种。%In view of the Bohai rim region had poor saline soil,severe drought,the ecological characteristics of natural disasters.So we went to resolve the lack of problem on drought resistance,salt tolerance,water-saving high-yield varieties in wheat production.Identified with multi-resistant(drought resistance,salt resis⁃tance,cold resistance,dry-hot wind resistance,disease resistance,lodging resistance),water saving,high yield and stable yield for breeding goal,to enrich the genetic basis of wheat varieties,improve the level of vari⁃ety yield potential and resistance as the breakthrough point,improvement the selective on the settings of en⁃vironment,innovation of drought resistance and salt tolerance in breeding methods.We bred the breeding va⁃rieties of wheat,which as the main characteristics on drought-resistant and salt-tolerant and fertility.
