| 摘 要： | 分离提取了126个马铃薯品种(系)基因型的块茎内源淀粉，用Hovenkamp-Hermelink J．H．M的方法测定了其直链淀粉含量，用ANOVA比较分析了块茎成熟期基因型和品种基因型的直链淀粉含量，其基本结论是品种基因型间直链淀粉含量存在极显著差异，而成熟期基因型间直链淀粉含量不存在差异，该结论为淀粉品质改良提供基本依据和数据。

| Abstract: | Through approach used by Hovenkamp-Hermelink J.H.M,novel starches from tubers of 126 potato cultivars are isolated and amylose contents are measured. By comparison of amylose contents with ANOVA between different genotypes of the cultivars as well as genotypes of maturity,it is concluded that there is a significant difference in amylose contents between different genotypes of the cultivars rather than between genotypes of tuber maturity. The result is a primary data in starch quality improvement. |
