| Research Abstract |
Interspecific and intergeneric cross pollination was performed using several colchicaceous ornamental plants. Following ovule culture, intergeneric hybrids were successfully obtained among Gloriosa spp., Littonia modesta and Sandersonia aurantiaca. These intergeneric hybrids had novel morphological characteristics compared with their parents, indicating the validity of intergeneric hybridization in the improvement programs of colchicaceous ornamentals. Since parental chromosomes in the intergeneric hybrids could be clearly discriminated by GISH sequence homology among Gloriosa, Littonia, and Sandersonia may be relatively low.
