Abstract
Two cases of hermaphroditism in Fragaria moschata Weston, (2n = 42), are described from Finland. One of them is a mutation in a clone known as a female since 1941 but appearing as a somatic segregant in 2013. The clone also carries a recessive gene for yellow-green leaf variegation. The mutations probably date back to the airborne radioactive fallout from the fire of the Chernobyl nuclear power plant in the Soviet Union in 1986. By interspecific crosses with the diploid (2n = 14) strawberry species, F. ×bifera Duch., Fragaria vesca L., and Fragaria. viridis Weston, the genetic determination of sex in F. moschata was studied and shown to depend on different genetic mechanisms in the two hermaphroditic musk strawberries. Selected tetraploid hybrids from crosses between musk and diploid strawberry species provide a wide variation of berry flavor and may have used as home garden strawberries. Two spontaneous hybrids between F. moschata and F. vesca are shown.
