The objective of this work was to study the pollination influence on Nova tangelo seed production. The experiment was carried out in the Pólo de Desenvolvimento Tecnológico dos Agronegócios do Sudoeste Paulista/DDD, Capão Bonito, SP, Brazil, during 2004/2005 crop. Nine years old flowers of Nova tangelo plants were treated as follows: 1. Valencia sweet orange pollination; 2. Natal sweet orange pollination; 3. Pera sweet orange pollination; 4. emasculated flower isolation; 5. complete flower isolation and 6. Check (free flower). In May 2005, the fruits were harvested. The highest harvested fruits percentage was obtained in Pera sweet orange treatment (42%). No fruits were obtained in treatments 4 and 5, suggesting that this tangelo did not develop partenocarpic fruits in this study conditions. In cross-pollination treatments was observed between 20 and 23 seeds in the fruits, which shows an evident pollination influence on fruit characteristic. No significant differences were noticed in fruit quality.
