| Research Abstract |
Spinach is generally considered as a dioecious species, while monoecious individuals with both sex functions can be found in certain varieties and lines. We showed that a single, incompletely dominant gene is responsible for the monoecious character. The gene was found to be located at a distance of 4.3cM from microsatellite marker SO4, which mapped 1.6cM from X/Y controlling sexual dimorphism in dioecious lines. This indicates that the monoecious gene is allelic to or closely linked to the X/Y gene pair.
