The low yield obtained on squash hybrid seed production in Brazil has contributed for an increasing of seed import, mainly from Japan. A field trial was carried out at Embrapa Vegetables, Brazil to evaluate the effects of amount and arrangement of pollinated flowers in the production and physiological quality of 'Jabras' hybrid seeds, a tetsukabuto type squash. The experimental design was randomized, using three replicates of 20 plants plot-1 and six treatments, pollinating the following flowers: first; first and second; only first, second and third; only second; second and third; and only third. The pollination of the first or second flower, independently of their location, resulted in the highest seed production due to the higher fruit set.
