摘　　要：为了明确从国内外引进的马铃薯种质资源在定西旱作区的表现,分早熟、中熟、晚熟,采用对比法对45份马铃薯种质资源的形态学特征、生物学特性进行了鉴定分析和评价。试验结果表明:在引进的45份材料中,晚熟材料有23份,田间抗病性强的材料有10份,抗旱性强的材料有23份,商品薯率在80%以上的材料有8份。对种质资源进行育种利用,通过配置优良组合,进一步挖掘资源潜力,筛选出‘冀张薯8号’等优良亲本材料。同时提出加强种质资源的深入鉴定,进行以拓宽遗传基础为主要目的的种质创新,丰富其遗传多样性,为以后针对不同用途利用这些资源提供有价值的参考依据。In order to study the performance of potato germplasm resources which were introduced from home and abroad in Dingxi dryland, including early, medium and late maturity, 45 potato germplasm resources were appraised and evaluated for their morphological features and biological characteristics by the method of comparison. The test results showed that out of 45 germplasm resources there were 23 late maturing stocks, 10 disease resistant stocks, 23 drought resistant stocks and 8 stocks which produced more than 80% marketable potatoes. Some of these germplasm resources were used in potato breeding. By making various crosses, the introductions were explored for their potentials and superior parents, for example ‘Jizhangshu 8＇, were identified. It was also proposed that it should emphasize on further identification of germplasm resources, broadening the genetic basis for germplasm, enriching genetic diversity and finally providing valuable references for future use of these materials for different purposes.
