Abstract: Some valuable wheat mutants were obtained by transferring exogenous DNA into wheat mediated by ion beam transformation.The variationfeatures of the leaf traits of the mutants were analysed.The result shows that the length and width of both the flag leaf and the 2nd leaf change obviously compared with control and reach a significant level no matter rain-fed and irrigated conditions.The dry/water ratio of the leaf traits of many mutantsis higher than the reference value,which states that their leaf traits under drought condition is thesame as irrigated condition's and the stability in both conditions is quite good.And among all of the mutants stands out a variant line whose number is 4342,for the dry/water ratios of the four index of its leaf traits are preferable to the reference,indicating its stability is the best in all the mutants.The results provide important bases for further improvement and utilization of the mutants.

Key words: ion beam mediated transformation, wheat, leaf, variation feature
