This paper presents the results of three competition trials of wheat cultivars (Triticum aestivum L.). They were carried out in low land conditions with irrigation, in São Paulo State, Brazil. The cultivars IAC-5, S-12, BH-1146 and IRN-526-63 were superior on the Mococa Experiment Station. The cultivars S-12 and Pitic-62 gave good results on Jamic Farm, Guatapará. The cultivars IRN-152-63, Sonora-63, LA-1434 and IRN-526-63 showed good performance in Pindamonhangaba. Besides grain yield, plant height, lodging and resistance to diseases number of kernels and number of spikelets per spike, spike length and number of grain per spikelet were also considered. A detailed description of the pedigree of each cultivar is given in this work.
