The family
Passifloraceae
contains over 580 woody or herbaceous species (
1
), the majority of species within the genus
Passiflora
being found in tropical South America.
Passiflora eduhs
fv. flavicarpa is considered to be the most important species (
2
) because of its value in the fruit juice industry. Additionally, this species is resistant to the soil-borne pathogen
Fusarium oxysporum
and, consequently, is frequently used as a rootstock onto which is grafted
P edulis
Sims. Interspecific sexual hybridization has been attempted in
Passiflora
breeding programs, using wild-type germplasms to transfer disease resistance and other potentially desirable traits into cultivated species. However, fertile hybrids have been difficult to obtain (
3
). Somatic hybridization provides a means of circumventing such sexual incompatibilities. Indeed, novel fertile somatic hybrids have been produced between
P. eduhs
fv. flavicarpa and
Passiflora incarnata
(
4
). Since the latter species can survive winter temperatures of −16�C, such transfer of cold tolerance to the commercial crop would permit cultivation in more temperate climates (
5
). Somatic hybrid plants have also been produced between
P edulis
fv. flavicarpa and
Passiflora amethystina, Passiflora cincinnata, Passiflora giberti
, and
Passiflora alata
, respectively (

).
