Fifteen triticale and three wheat cultivars were evaluated in three experimental trials carried out at the Santa Inês Farm, Maracaí, in the Paranapanema Valley during the years of 1979, 1980 and 1981. The wheat and triticale cultivars did no differ in relation to grain yield, however, the triticale TCEP-77138 presented high yield associated with resistance to stem rust, and with high weight of one hectoliter of seeds. Triticale cultivars were more sensitive than wheat to leaf diseases caused by Helminthosporium sp. and Septoria sp.
