１　前　言培育高淀粉马铃薯品种一直是马铃薯育种的目标。准确而有效地进行高淀粉低世代材料的鉴定和筛选，是加快育种过程的有效途径。目前，在育种中常采用比重法测定淀粉含量，该方法简单、快速，但需要足够量的块茎，而各品系在低世代选种圃块茎量都很少，无法进行分析。 1 Introduction Cultivating high starch potato varieties has been the goal of potato breeding. Accurate and effective identification of high starch and low generation materials screening is an effective way to speed up the breeding process. At present, the starch content is often measured by gravimetric method in breeding. The method is simple and rapid, but requires a sufficient amount of tubers. However, the amount of tubers in each generation is very low and can not be analyzed.
