Abstract: 【Objective】To screen the suitable potato varieties for the West Liaohe River Basin.【Methods】Seven new Dutch potato varieties with high yield,good quality,good potato type and disease resistance were tested by contrast method with Kexin No.1 as the control. The main evaluation indexes of high yield,marketability and quality,and other varieties were evaluated comprehensively.【Results】The results indicated that seven potato varieties grew well in the West Liaohe River Basin,and the tuber marketable rate of each variety ranged from 76.19% to 90.32%. The yield of Panamera was highest,which was 32 468 kg/hm2,which was significantly higher than that of the control variety(P<0.01);the yield of Lucinda was the second,which was 31 007 kg/hm2,which was also significantly higher than that of the control variety(P<0.01). The starch content of each variety varied from 12.44% to 15.14%. The starch content of Lucinda was the highest(15.14%)and Memphis content was the second(14.22%),both of which were significantly higher than that of the control variety(P<0.01).【Conclusion】Panamera and Lucinda were outstanding comprehensive characteristics,which were suitable for promotion in the West Liaohe River Basin.
