摘　　要：利用2005-2018年黄淮冬麦区旱肥地区试结果,分析了黄淮冬麦区旱肥地小麦品种主要性状的演变情况。结果表明,随着年份的推进,产量水平整体表现为不断提高,小麦产量三要素中有效穗数表现为逐渐提高,穗粒数和千粒质量表现为先增加后减少;株高与最高群体随年份的推进整体起伏不大,呈基本稳定的态势;反映旱肥小麦品种品质的指标湿面筋随年份的推进呈先减少后增加的趋势,而稳定时间随年份的推进呈先增加后趋于稳定的趋势;小麦品种的抗旱性随年份的增加呈降低趋势,可能是育种人员着重提高品种的产量而对育成品种的抗旱性重视程度有所下降所致。The main characters of wheat varieties in the drought and fertilizer group in Huang-huai winter wheat area from 2005 to 2018 were analyzed.The results showed that with the advance of the year,the yield level was continuous improvement,kernel number increased gradually,spike number and thousand grain quality increased first and then decreased.The plant height and the highest population did not fluctuate significantly with the advance of the year.Wet gluten decreased first and then increased,settling time increased first and then tends to be stable with the advance of years.The drought resistance of wheat varieties decreased with the increase of years,it may be that breeders pay more attention to increase the yield of varieties and pay less attention to the drought resistance of bred varieties.
