| Research Abstract |
In this study, we investigated the morphology, inheritance and responsible gene analysis of the valuable flower form mutations in evergreen azalea cultivars. These flower form mutations include, hose in hose form; petaloid sepal, long lasting flower form; sepaloid petal, double form; petaloid stamen and/or pistil, spider form; staminoid or narrowed petal etc. and these mutational trait could find in varieties of each wild species. These mutations would be caused by homeotic gene mutations. Each mutational forms would be explained by changes of expression patterns and DNA structure of correspond MADS genes, hose in hose form; PI (B class), long lasting flower form;AP3 (B class), double form and spider form; AG (C class).
