| Abstract: | This study evaluated the effects of water stress on the yield, drought-tolerant coefficient, drought-tolerant index, the content of malondialdehyde (MDA), soluble sugar and dissociation proline of the eight potato varieties using pot experiment. The results showed that Mila, Bashu NO.10, Daxiyang and Zhongshu No.3 had strong drought tolerance, Dixirui and Feiwuruita had middle drought tolerance, Hui-2 and Hezuo 88 had weak drought tolerance. The four potato varieties with strong drought tolerance, Mila, Bas... |
