Outline of Final Research Achievements

Though triploid natures is better than diploid one in ornamental plant, occurrence mechanism of triploids is not known in detail.
In two 2x-2x cross combinations that could produce mainly triploids, unreduced gamete forming pattern were investigated by SSR markers. It was suggested that the unreduced gamete of allo-diploids, which have two different genomes, were formed via inhibition of meiosis I. However, it was also suggested that the unreduced gamete of auto-diploid, which have two same genomes, were formed via inhibition of meiosis II.
High pollen fertility could be detected from three plants with diploid chromosome numbers obtained from the crosses using the triploid Lychnis senno as parents. However, weak growth were shown from three seedlings obtained from the cross of Lycoris radiata used as maternal.
