13个马铃薯品种(系)品比试验的结果表明，L13120-1、L13105-10综合性状优良，表现突出，L13120-1折合产量26 498 kg/hm2，较LK99增产5.97%，较费乌瑞它增产129.83%，商品薯率为87.87%，大薯率为52.30%，干物质含量17.52%，蛋白含量2.54%，淀粉含量14.84%，还原糖含量0.39%，Vc含量14.57 mg/100 g；L13105-10折合产量 25 548 kg/hm2，较LK99增产2.17%，较费乌瑞它增产121.59%，商品薯率为77.53%，大薯率为47.58%，干物质含量19.92%，蛋白含量2.39%，淀粉含量16.54%，还原糖0.30%，Vc含量16.71 mg/100 g。建议推荐参加2019年甘肃省马铃薯多点试验。

The comparison test of 13 potato cultivars (lines) showed that the comprehensive characteristics of L13120-1 and L13105-10 were excellent and outstanding. The yield of L13120-1 was 26 498 kg/hm2， which was 5.97% higher than that of LK99， 129.83% higher than that of FAVORITA. The commercial potato yield was 87.87%， the big potato rate was 52.30%， the dry matter content was 17.52%， the protein content was 2.54%， the starch content was 14.84%， the reducing sugar content was 0.39%， the Vc content was 14.57 mg/100 g， and the yield of L13105-1 was 25 548 kg/hm2， increased by 2.17% compared with LK99， 121.59% higher than that of FAVORITA. The commercial potato rate was 77.53%， the big potato rate was 47.58%， the dry matter content was 19.92%， the protein content was 2.39%， the starch content was 16.54%， the reducing sugar content was 0.30%， and the Vc content was 16.71 mg/100 g. It is suggested that the two lines to be enrolled in the Potato Multi-point Experiment in Gansu Province in 2019.
