Interspecific hybridization between Argentinean species pf genus Passiflora subgenus Passiflora

Abstract

Interspecific hybridization is one of the most important sources to increase genetic variability in plant breeding. Passiflora is the largest genus of the Passifloraceae family, it has many species and great phenotypic variability. There are nineteen species of passiflora native to Argentina, within four taxonomic subgenera: Passiflora, Decaloba, Dysosmia and Tacsonioides. Unlike most species of the genus distributed in warmer regions, some Argentinean species would tolerate colder climates.
