"Fairmount 1 thorny" ("FM1 thorny") (a Rosa multiflora Thunb ex. J. Murr.) and a thornless sport of "FM1 thorny" ("Fairmount 1" ("FM1")) were established in vitro to investigate chimeral segregation under various levels of BA and to obtain a pure thornless rose. While the chimeral thornless sport was expected to segregate in vitro and yield both thorny and thornless plantlets, "FM1 thorny" was to yield only thorny plants. "FM1" segregated in vitro into its constituent genotypes and yielded thorny and thornless plantlets, suggesting that "FM1" is chimeral. "FM1 thorny" produced only thorny plants in vitro. These results indicate that the "FM1 thorny" clone was not chimeral (pure thorny) and that the thornless regenerates of "FM1" did not develop via somaclonal variation. There was a significant linear relationship between increasing BA concentration and the percentage of thorny plants. Among a population of 690 tissue culture derived plants from all the BA experiments, 6 plants were classified as pure thornless plants 1 year later.
