PCR-RFLP analysis was conducted to clarify the relationship between the leaf color of progenies and their ptDNA inheritance in interspecific three-way crosses, (Rhododendron kiusianum x R. eriocarpum) x R. japonicum f. flavum. All albino progenies contained maternal ptDNA, whereas green and pale-green progenies contained paternal ptDNA. Sectorial chimeric progenies, of which the leaf and shoot color was turned from green to albino during the culture, contained both maternal and paternal ptDNA in green segments and maternal ptDNA in albino segments. These results suggest that albino progenies are caused by the incompatibility between plastome from F1 hybrids of R. kiusianum x R. eriocarpum and nuclear genome from R. japonicum f. flavum.
