Abstract: The compatibility of selfpollination and crosses between cultivars in the same hybrid group or in different hybrid groups was studied in this paper.
Individuals crossing exclusively within the same population produce more progeny than those crossing in both directions and thereby use up some of their gametes for the production of inviable hybrids.
