SUMMARY It was studied the relationship between the wheat infection by Cochliobolus sativus(H -Iminthosporium sativum) and plant age under greenhouse conditions. The results showed that the cultivar IAC 5 and Alondra 4546 were similarly susceptible to C. sativus in leaves showing an increase of the susceptibility starting from the inicial stages to the terminal stages of the growth. The symptoms in the internodes were more severe on cultivar Alondra 4546.
