Abstract: Afield micro -plot experiment on the interrelationship between water use efficiency and nitrogen use efficiency of different wheat evolution materials at the whole plant level showed that both water and nitrogen use efficiency increased gradually during the long evolution process from diploid to hexaploid.The water use efficiency was positively related with nitrogen use efficiency across nine evolution materials excluding French S.cereals, suggesting that the high nitrogen use efficiency of French S.cereals might be related with physiological mechanisms other than WUE.

Key words: Wheat evolution materials, Water use efficiency, Nitrogen use efficiency
