Natural hybridization of Yezo and Sakhalin spruce in central Hokkaido, revealed by DNA markers with contrasting modes of inheritance
Abstract Yezo spruce ( P icea jezoensis var. jezoensis ) and Sakhalin spruce ( P icea glehnii ) occur across H okkaido and co‐occur in some forest habitats. This leads to the potential for natural hybridization between these two species, which has been shown to occur at low frequencies. The purpose...

One natural hybrid harbored G ‐type cp DNA , J ‐type mt DNA and J / G ‐type n SSRs , which implies that hybrids produced by J (female) × G (male) crossings occur at low frequencies. The two remaining hybrids harbored J ‐type cp DNA and mt DNA with either J / G or J / J ‐type n SSRs , suggesting that they may be F 2 hybrids resulting from backcrossing between an F 1 hybrid and a Y ezo spruce.
