摘　　要：为探明马铃薯新品系的抗旱能力及其品质特性,本研究以5个马铃薯新品系为材料,测定各新品系的生理生化指标并评价其抗旱性。结果表明,随着干旱胁迫程度的增加,株高和茎粗呈下降趋势,丙二醛、可溶性糖含量呈上升趋势,CAT先上升后降低,JWS-1、JWS-2、JWS-3和JWS-4的POD和SOD活性呈上升趋势,JWS-5为先上升后降低;抗旱系数、抗旱指数结果和综合抗旱隶属函数评价结果显示,新品系JWS-2和JWS-3的抗旱性较强;马铃薯淀粉含量在18%以上的新品系有JWS-2和JWS-4,还原糖含量低于0.2%的新品系有JWS-1和JWS-4,维生素含量大于20 mg/100 g的新品系有JWS-1、JWS-2和JWS-5;筛选出1个抗旱淀粉加工型新品系JWS-2,1个薯片加工型新品系JWS-4,2个鲜食新品系JWS-1和JWS-5。In order to investigate the drought resistance and quality characteristics of five new potato(Solanum tuberosum)strains,the physiological and biochemical indexes of each strain were determined and the drought resistance was evaluated.The results showed that with the increase of drought stress degree,plant height and stem diameter decreased,malondialdehyde and soluble sugar contents increased,CAT increased first and then decreased,POD and SOD activities of JWS-1,JWS-2,JWS-3 and JWS-4 increased,and JWS-5 increased first and then decreased.The results of drought resistance coefficient,drought resistance index and comprehensive drought resistance membership function evaluation showed that the new strains JWS-2 and JWS-3 had strong drought resistance.JWS-2 and JWS-4 with starch content were above 18%,JWS-1 and JWS-4 with reducing sugar content were below 0.2%,and JWS-1,JWS-2 and JWS-5 with vitamin content were above 20 mg/100 g.A new strain of drought-resistant starch processing JWS-2,a new strain of potato chip processing JWS-4,and two new fresh food strains JWS-1 and JWS-5 were selected.
