In order to obtain an acceptable yellow passion-fruit cultivar, productive and uniform in fruit quality, this research was carried out at Monte Alegre do Sul, SP, Brazil, from 1995 to 1997. The behavior of eight hybrids was studied. Vegetative growth, flower types, flowering and fruiting, yield, fruit quality (including fruit weight, fruit size, pulp, internal color, average seed number/fruit), total soluble solids (TSS) and commercial patterns were analysed. The best passion fruit cultivars were 'IAC-3', IAC-5' and 'IAC-7' hybrids, preseting curved-thread flowers (above 93%), yield of approximately 47 ton ha-1, oval and compact fruits, and an orange-intense pulp color; the average fruit weight was 170 g to 218 g, TSS varied between 15 and 16°Brix, equivalent to 51% of the pulp, with 400 seeds per fruit. Their fruits were rated in the two superior classes of the Brazilian fresh fruit market, being more than 8.8 cm long and 7.3 cm wide. Results indicated that these hybrids attend the São Paulo market exigence. They became the 'COMPOSTO IAC-27' cultivar.
