Resumo: Yellow passion fruit (Passiflora edulis f. flavicarpa) is a self-incompatible crop with purple corona flowers (PCF). Plants exhibiting white corona flowers (WCF) were observed in an experimental field located in Campos dos Goytacazes - RJ, Brazil. This study was performed in order to test the fertility of these genotypes through studies of in vivo pollination, meiotic behavior and pollen viability. Using in vivo pollination, the mean fruit set percentage, obtained from self-pollinations at the moment that flowers open, was 70.83% in WCF and 0% in PCF. In terms of cytological analysis, for both kinds of plants, WCF and PCF, the meiotic behavior was considered regular, considering the high meiotic index estimated for both of them, 96.3% and 97.7%, and pollen viability, 98% and 99.5%, respectively. Such results suggest that the genotype WCF is self-compatible and interesting for use in genetic improvement of yellow passion fruit.
