摘　　要：以8858-2为母本,陇春8号为父本,通过有性杂交,水旱轮选,培育出抗旱丰产春小麦新品种陇春27号。试验表明,陇春27号在2006-2007年国家小麦西北旱地组区域试验中,平均产量分别为180.83 kg/667m^2和201.87 kg/667 m^2,分别较统一对照定西35号增产4.91%和21.37%,增产极显著,均居第一位;2008年生产试验,平均产量227.67 kg/667m^2,较统一对照定西35号平均增产12.71%。抗旱性指数2006年为1.1835,2007年为1.1014,显著优于对照品种定西35号,是所有参试材料中抗旱性最强的品种。陇春27号抗旱性强,适应性广,丰产稳产,在西北旱地农业区具有广阔的应用前景。A new spring wheat variety,Longchun 27 with good drought tolerance and high output,was bred by the sexsual hybridization（8858-2×Longchun8）,recurrent selection in irrigation and drought environments in order to promote wheat production level in northwest arid areas and speed up cultivar replacement.The tests showed that the average yield of Longchun 27 was 180 kg/667m^2 and 201.87 kg/667m^2,which was first in all tested materials,and increased by 4.91% and 21.37%（up to significant level） in comparison with the common check Dingxi 35,respectively,in national regional experiment of northwest dryhand spring wheat group in 2006 and 2007;it was 227.67 kg/667m^2 and 12.71% more than that of Dingxi 35 in 2008 production test.On the other hand,the drought tolerance of Longchun 27 was the best compared with that of Dingxi 35 and other varieties（lines） during the above experiments,and its index of resistance to drought was 1.1835 in 2006 and 1.1014 in 2007.So it will produce wide prospect to grow Longchun 27 in northwest arid region of China due to its high yield and drought tolerance.
