11个冬小麦品种(品系)抗旱性与产量性状研究

摘要

[ Objective ] To breed fine wheat cultivar that is suited to plant in Hebei and other winter wheat planting areas in north China.[ Method ] 11 wheat cultivars (strains) were selected for drought tolerance determination and yield property analysis in different study plot.The drought tolerance, yielding ability and stable yield ability as well as the relations among three factors were researched. [ Result] In the 11 winter wheat cultivars (strains), Zhongmai 12, Cangmai 6002 and Cangmai 6003 possessed the characteristics of drought tolerance, yielding ability and stable yield together. Linhan 536 had better drought tolerance and stable yield, Handan 00 -415 has strong drought tolerance but poor stable yield. [ Conclusion ] The study provided theoretical reference and scientific proof for breeding wheat cultivar with drought tolerance, high yield and stable yield in north China.%[目的]选育出适于河北省及北方冬小麦区域种植的优良小麦品种.[方法]以11个冬小麦品种(品系)为试材,对11个冬小麦品种(品系)进行不同区域多点抗旱性鉴定和产量性状分析,研究不同小麦品种(品系)的抗旱性、丰产性和稳产性,以及三者之间的关系.[结果]11个冬小麦品种(品系)中同时兼具抗旱、丰产和稳产的品种(品系)为中麦12、沧麦6002和沧麦6003,临旱536具有很好的抗旱性和稳产性,邯郸00-4015具有很强的抗旱性,稳产性较差.[结论]该研究为北方区域选育抗旱、高产、稳产小麦品种提供理论参考和科学依据.
