Summary: Brazil is the largest producer of passion fruit, however, little is known about the adaptability of cultivars recently launched in different producing regions. The objective of this work is to evaluate the vegetative and reproductive development of five sour and three sweet passion fruit cultivars, on the north coast of Espírito Santo. The cultivars of sour passion fruit (Passiflora edulis Sims f. flavicarpa) were evaluated ('BRS Gigante Amarelo', 'BRS Rubi do Cerrado', 'BRS Sol do Cerrado', 'FB-200 Yellow Master' and 'FB-300 Araguari'). The sweet passion fruit cultivars were P. setacea DC. (‘BRS Pérola do Cerrado’), P. cincinnata Mast. (‘BRS Sertão Forte’) and P. alata Curtis (‘BRS Mel do Cerrado’). The experiment was conducted between August 2021 and July 2023, in the municipality of Sooretama/ES, using a randomized block design with 8 treatments, 9 replications and 5 plants per plot. Vegetative development was evaluated after 50 and 90 days after transplanting. The productivity and physical-chemical quality of the fruits were evaluated during two production cycles. Analysis of variance was performed and means were grouped using the Scott Knott test (p<0.05). Vegetative development was higher in ‘BRS Sertão Forte’, while it was lower in ‘BRS Mel do Cerrado’ and ‘BRS Pérola do Cerrado’. The highest productivity was obtained in sour passion fruits compared to sweet ones, however, the harvest was staggered throughout the year. Production was higher in ‘FB-300 Araguari’ and ‘BRS Rubi do Cerrado’, while the quality of the fruits was similar among the sour ones. ‘BRS Pérola do Cerrado’ had a higher number of fruits and vitamin C, while ‘BRS Mel do Cerrado’ had a higher soluble solids content and ratio. Staggered harvesting can be an alternative for distributing the farmer's source of income, while the different quality between cultivars allows different markets to be reached.
