| Abstract:
We have obtained information on relationships among wild gladiolus species through RAPD analysis (Takatsu et al., 2001b). Interspecific hybridization has been carried out based on a dendrogram and F1 seeds have been derived from seven reciprocal crosses. However matured seed was not obtained from the crosses using Gladiolus orchidiflorus as a female parent. We have made a segregation population (F2) derived from interspecific hybridization between G. tristis and G. gracilis for selection of a RAPD marker linked to a floral scent trait of the wild species G. gracilis. Floral scent of each plant was evaluated by sensory evaluation in the F2 plants and it was shown that a segregation ratio of scented plant and non-scented plant fit a 1:3 (χ2-value=0.09) ratio. | |
