    In order to screen or breed the Chinese cabbages with more robust tolerance to high temperature, we have analyzed the genetic diversity of the collected 78 Chinese cabbages, and applied the natural high temperature in summer in Wuhan to investigate the Heat Injury indexes. We have identified one variety (C72) showing a good performance when suffering from heat stress, and this is consistent with the physiological indexes including MDA, POD, SOD, and electrical conductivity. The findings of this study will give instructions on selection of Chinese cabbages that are suitable for growing in summer in the basin of Yangtze river, which is essential for the whole-year supply of Chinese cabbage.
