Twelve cucumber hybrids were evaluated in summer (two replications of seven plants) and fourteen in autumn-winter (four replications of five plants), in a randomized block design to evaluate their performance under protected cultivation at Sao Manuel, São Paulo State, Brazil. Only 'Rensei' was ginoiceous, while the others (AF-1327, AF-1328, AF-1329, BU-92, Hokuho, Hokushin, Hyuma, KH-705, Natsusuzumi, Nikkey, Summer Green, Top Green, Tsuyataro and Yoshinari) were monoiceous, although all of them were partenocarpic. The most yielding hybrids in summer were Tsuyataro (25,4 fruits/plant) and Rensei (25,3 fruits/plants). The most yielding in autumn-winter were 'Nikkey' (26,8 fruits/plant) and 'Top Green' (23,4 fruits/plant) and the least yielding were 'Rensei'(16,1 fruits/plant) and AF-1328 (17,6 fruits/plant). Higher yieldings were obtained in autumn-winter sowing than in summer.
