Selected germoplasms of wheat were tested for yield potential and resistance to rusts and by cultivar trials in the State of São Paulo. Performance was evaluated in several locations in 1971 and 1972 in the wheat area of the State on Latossolic B "Terra Roxa" soils. The cultivars Pel 4178-67, IAC-5, IAS-55, IRN-526-63, Londrina, Pitic-62, Cotiporã, IAS-54 and LA-1434 showed superior performance for yield. The cultivars Pel 4178-67 and Paraguai-214 showed good resistance to leaf and stem rust while the cultivars BH-1146, IAS-51, IAS-54, IAC-5, IRN-526-63, LA-1434, Pel 14603-64, S-12, S-43, Santa Elena and Pel 13180-65 were susceptible to leaf rust. The cultivars IAC-8, BH-1146, S-43, Pel 13295-65, IAC-5, S-12, Cotiporã, Pel 14603-64 and Santa Eelena were susceptible to lay.
