摘要
本试验采用田间鉴定法,两年来通过对12个不同莜麦品种(品系),在不同生育时期的抗旱形态指标、抗旱生理指标和丰产性状等指标的测定,经过多方面比较,综合分析,肯定了高8—21、高8—25、578、7413、华北二号等为抗旱性强,经济性状表现好的品种,是目前我区旱地莜麦良种不足,产量不高情况下,最适宜于内蒙西部旱作区推广、应用的优良品种,该品种随着生产上的使用,对提高我区莜麦产量,将会有着积极作用。
This experiment was conducted in the field Through 2—year's observation and measurement. The morphological physiological and Productivity charactors of 12Naked oat varieties(or lines)was determined in different development period By comparing and analysing these charactor.it is confirmed that variety high—8—21、high8—25、578, 7413,and Huabei No 2.have high drought resistance and good economic charactor, At present,it is snitable to adopt these varieties in our arid areas where these are few good varieties, As these varieties are adopted in production, The must play an active part in improving The yield of Naked oats in our antonomous region.
