Recombination of three genomes would produce new phenotypes having high ornamental value. The fertile pollen of (T. bicolor × T. baillonii) was mounted on the stigma of four species, T. concolor, T. fournieri, T. hirsutissima and T. siamensis. Only the cross combination of T. fournieri × (T. bicolor × T. baillonii) produced five progenies. Then three hybrids (T. fournieri × T. baillonii), (T. fournieri × T. bicolor) and (T. bicolor × T. baillonii) were used as female parents then cross with other Torenia species. Three progenies were obtained from (T. fournieri × T. baillonii) × T. siamensis and two progenies were obtained from (T. fournieri × T. baillonii) × T. concolor. The hybridity of progenies was confirmed by PCR-RFLP, and all tested plants were true hybrids. Tri-parental hybrids showed intermediate chromosome number between parents and all tri-parental hybrids were male sterile. Petal color of the hybrids was mostly intermediate of parents with narrow variation.}, pages = {17--23}, title = {新規トレニア三元交配種の作出}, volume = {72}, year = {2020}, yomi = {ラオジュンタ, タナポーン and ナルミ, タカコ and フカイ, セイイチ} }
