The results showed that the trait values of grain yield per plant （GYP）, effective panicles per plant （EPP）, seed-setting rate （SSR）, panicle length （PL）, leaf relative water content （RWC） and chlorophyll content （SPAD） in all tested varieties decreased significantly under the conditions of drought stress. The subordinate function values of these traits of all tested rice varieties were thus calculated varieties. Based on the aver- age subordinate function values of all these traits, total 7 （i.e. Y Liangyou 1） and 3 （i.e. Liangyou Peijiu） rice varieties were identified as drought-tolerant and drought- sensitive varieties, respectively.展开更多
