Abstract: In order to investigate the identification index of drought resistance in the forage triticale seedlings, 30 triticales withdifferent genotypes were identified by 20%–PEG6000. Results showed that responses of each gene to water stress wererelatively obvious, water content decreased, the root-shoot ratio enhanced, and leaf curvature and root hyperplasied;There was significant difference among different genotypes, material 27,29,30 showed a good representation to waterstress, and their root status were also good. The variation regularity of water content and root hyperplasia was good andthey had a great significant correlation. But the variation of root-shoot ratio is relatively complex, other factors shouldbe taken further consideration in the application.
