Research Abstract |
We showed that flowering time and flower color of Hemerocallis fulva ; Pollination by swallowtail butterflies and H. citrina ; Pollination by hawkmoths were regulated by major loci using segregation of F2 hybrids. We successful for genotyping individual pollen grains, thus we showed that swallowtail butterflies preferentially visited reddish flowers and hawkmoths preferentially visited yellowish flowers. We evaluated the possibility of the evolution by simulation using our genetic and experimental data. We found that flowering time having pleiotropic effects both on natural selection and assortative mating, and promote evolution of H. citrina from H. fulva.
