Shanxi Province is one of the major producing areas for seed potato and commodity potato in China.However,due to drought and water shortage,the development of potato production was severely restricted.In order to screen out potato varieties with strong drought resistance,this paper conducted drought resistance identification on 15 potato varieties introduced from abroad and cultivated in pot;and analyzed drought resistance coefficient,drought resistance index,plant height stress index,and water loss rate of isolated leaves of each variety.The results showed that the plant height stress index and water loss rate were extremely significantly negatively correlated with drought resistance coefficient and could be used as indicators to identify drought resistant ability.Based on these results,4 drought-resistant varieties out of the 15 tested varieties,‘Zhongshu No. 19’,‘Jinshu No.24’,‘Jinshu No.16’ and‘ Tongshu No.29’ were screened.They are suitable for planting and extension in northern Shanxi.
