The experiment was installed in field and aimed to compare the performance of eight hybrids of summer cauliflower. The statistical design was the randomized blocks with eight treatments and four replicates. The experimental plot measured 14 m², with 28 plants of cauliflower spacing 1.0 m between rows and 0.5 m between plants. It was considered for evaluation 10 plants of the two central rows of each plot and the following hybrids of cauliflower: TPX00123, TPC00218, Sarah AF-1169, Sharon, Snow-Flake, First-Snow, Veneza and Verona. Top-dressing was carried out with 10,5 kg of ammonium sulfate and 2,8 kg of potassium chloride, applied at 15, 30, 45 and 60 days after the seedlings transplantation. The cauliflowers were harvested at the ideal moment, with compact heads and united flower buds. The hybrids TPC00218 and TPX00123 were promising, with commercial productivity of 23.8 and 23.2 t ha-1, respectively. The hybrid First-Snow presented low plant development and good productivity, so it can be cultivated with smaller spacing among plants. The hybrid Snow-Flake presented the lowest productivity, so it is not recommended for the region of Jaboticabal. All tested hybrids had its production classified as "extra"and class 8 (greater than 230 mm).
