ABSTRACT: The selection of parents to obtain new Camellia japonica cultivars is hindered by the fact that flowers of many cultivars do not have operative reproductive organs and for there is not information on the fertility of the ornamental camellia cultivars. In the present work, the production and fertility of the pollen of 15 C. japonica cultivars was evaluated to select male parents to obtain interesting commercial cultivars. Flower samples were taken to remove anthers to obtain pollen, estimating the weight of the pollen released by each flower. Pollen germinability rate studies were carried out using fresh and frozen pollen. Cultivars 'Thelma Dale' and 'Silver Cloud' proved to be the best candidates to be used as parent pollen producers to create new cultivars, since they produce enough quantity of pollen and present a germinability higher than 40%.

Key words: Camellia japonica, cultivars, parental selection.
