A study was made on the performance of wheat cultivars tolerant, non tolerant to aluminum toxicity and commercial cultivars in several regions of State of São Paulo, during the cropping season of 1979 and 1980. In the trials of cultivars for soils with Al3+ only the cultivars IAC-21 and BR-4 were superior to the control BH-1146 in yield in the studied biennium. In the tests of cultivars for soils without Al3+, Tucano, Anahuac, SEMA 220, El Pato, Mitacoré, Aracatu, MR-74042 and MR-74501 were higher in yield than the control. In 1979/80, the cultivars IAC-13, INIA-66, Itapua-5, PAT-24, IAC-17, IAC-5, BH-1146 and Tobari-66 showed superior performance for yield. In a general way, the cultivars PAT-24, IAC-13, INIA-66, CNT-8, Alondra, MR-74044, MR-74501 and Sparrow "S" showed resistance to prevalent races of Puccinia graminis f. sp. tritici. Cultivars Mitacoré, Aracatu, Alondra and CNT-8 presented lower susceptibility to P. recondita under field conditions.
