To innovate the adjusting model of potato planting structure, improve planting benefits, and speed up the popularization and application of the potato variety ‘Xisen 6’ in China, variety demonstration tests were conducted in Tianshui and Dingxi of Gansu, and Wufeng, Xingshan, Badong Chazidian, Jianshi Longping, Lichuan, Tianchishan, Zhushan of Hubei, by taking local main varieties as control, to observe and verify the stability and adaptability of the comprehensive traits of ‘Xisen 6’. Compared with main local varieties, the tests showed that, except Dingxi, Xingshan and Zhushan had small yield increase (3.13%, 7.71%, and 6.91%, respectively), the remaining 6 test sites had significantly higher yield increase than the control, the yield increase in Tianchishan was 36.01%, in Badong was 48.37%, in Jianshi Longping was 34.39%, in Wufeng was 51.60%, in Lichuan was 28.66%, and in Tianshui was 28.63%. It is indicated that ‘Xisen 6’ has strong adaptability, can grow and mature normally in all test sites, and its yield is higher than that of main local varieties.
