Challenges in breeding and selecting Passiflora edulis f. flavicarpa× P. incarnata hybrids
September 04, 2023 | Technology in Horticulture |
Conducted by Mississippi State University, USA, this study delves into interspecific hybridization involving Passiflora species, particularly P. edulis and P. incarnata. While P. edulis is a prominent commercial species, P. incarnata thrives in more temperate regions. Previous attempts at interspecific hybridization have faced challenges in ensuring the hybrids' survival in subtropical and temperate climates.
Controlled crosses between P. edulis f. flavicarpa and P. incarnata were performed to gather baseline data on the resulting interspecific passionfruit hybrids. Fruit collection per hybrid selection varied significantly, with some producing no seeds while others yielded more than 25 seeds per fruit. The study observed a wide range in pulp weight, percentage, and fruit width among the hybrids. Notably, vines with P. incarnata from different geographic locations exhibited distinct characteristics, such as seed production, fruit weight, and shape.
Overall, the study offers cautious optimism regarding the potential of interspecific hybrid Passiflora involving P. incarnata. Further research, particularly involving backcrossing to P. edulis, is recommended to advance the development of these hybrids.
