Selected germplasms of wheat were tested for yield potential and resistance to rusts and cultivar trials in the State of São Paulo. Performance was evaluated in several locations in 1974 in the wheat area of the State on Latossolic B "Terra Roxa" soils. The cultivars IRN-526-63, IAS-55, Sonora-63, BH-1146, IAS-54, Londrina, LA-1434 and Pitic-62 showed superior performance for yield. The cultivars IAC-5, Sonora-63, Sonora-64 x Selkink, Triticum agropyrum, Tobai-66, IAC-11, Sonora-64, Norteno-67, and Super X showed better resistance to stem rust. The cultivars Super X, Sonora-64 x Selkink, IRN-152,63, and Triticum agropyrum, were more resistant to leaf rust. The cultivars BH-1146, IAC-5, Triticum agropyrum, IRN-152-62, LA-1434 and IAC-11 were susceptible to lay.
