摘 要:为推广应用抗旱丰产型小麦品种,解决北京市农业用供水不足的问题,采用种子萌发期、苗期和全生育期干旱胁迫3种方法,分别对北京地区11个小麦主栽品种进行抗旱性评价,将抗旱级别HR、R、MR、S和HS分别赋值5、4、3、2、1,并分别给予3种鉴定方法下的抗旱结果以20%、10%和70%的权重,计算出综合抗旱指数,同时结合籽粒产量,综合比较参试品种的抗旱性和丰产性。结果表明,综合抗旱指数在3.0以上、抗旱性优于或等于对照农大212的品种有农大3486、京麦8号、中麦415、农大5181、中麦175。结合胁迫后各品种的产量表现,农大3486、农大5181可作为北京地区抗旱丰产冬小麦首选品种,京麦8号可作为备选品种。In order to promote the application of drought resistant and high-yield wheat varieties and solve the problem of insufficient water supply for agriculture in Beijing,three methods of drought stress were used to evaluate the drought resistance of 1l main wheat varieties including seed germination stage drought-resistance,seedling stage drought-resistance,and full growth stage drought-resistance.The drought resistance levels HR,R,MR,S,and HS were assigned 5,4,3,2,and 1 respectively,and give the drought resistance results under the three identification methods weights of 20%,10%,and 70%to calculate the comprehensive drought resistance index.The results showed that varieties with a comprehensive drought resistance index above 3.0 and drought resistance better than or equal to the control Nongda 212 were Nongda 3486,Jingmai 8,Zhongmai 415,Nongda 5181 and Zhongmai 175.Based on the yield performance of various varieties under stress,Nongda 3486 and Nongda 5181 could be the preferred winter wheat variety for drought resistance and high yield in Beijing,and Jingmai 8 could be a candidate variety.
