Abstract
Hybrids of two extreme morphologically variable populations of Ipomoea triloba were produced with 12.5% success. Bagged flowers set 100% fruit showing the species is strongly self-compatible and only facultatively outcrossing (10-20%). Nevertheless, fruit and seed development, germination, growth and development, pollens and chromosomes of F1 hybrids were normal. Parents and F1 plants were diploid (2n=30). Hybrids morphologically resembled a wider spread of vigorous natural population. The taxonomic implication of the relationship is discussed.
