Abstract:: To study the effect of water conditions on growth and yield of different genotype and drought resistance winter wheat,In this paper,T.dicoccon Schuebl(original variety),T.aestivum L Xinong9871(sensitive modern wheat) and T.aestivum L Changwu134(drought-resistant modern varieties) were used in the experiment.The results showed that:T.dicoccon Schuebl wheat tillering and plant height are more severely affected by water supply,the irrigation in jointing has no significant effect on tiller and plant height to T.aestivum L Xinong9871 and T.aestivum L Changwu134.It shows that:the growth and development of original varieties are more significantly restricted by water than modern varieties.T.dicoccon Schuebl yields in different water conditions have no significant variation,but yields of T.aestivum L Xinong9871 and T.aestivum L Changwu134 with no irrigation are half of that with sufficient water,however,irrigation in jointing did not significantly increase yield,which means that the modern varieties yield is more affected by water than the original varieties.
