Abstract
The genetic relationships of Viola species in the subsection Patellare s were analysed using the random amplified polymorphic DNA (RAPD) meth od. Viola species from the series Chinensis and Pinnatae, and five hyb rid lines formed a cluster which divided into three subgroups. Viola s pecies in the series Variegatae and a hybrid line were clustered into a second group. The clustered (sub)groups from RAPD analysis are in ag reement with the conventional taxonomy based on morphological characte rs. Therefore, RAPD analysis can be used for providing an alternative classification system to identify genotypes and morphological characte rs of Viola species. However, although V. chaerophylloides, and V albi da and V. albida var. takahasii were classified into different series, Pinnatae and Chinensis, by morphological characters, they were cluste red together with a high similarity coefficient by RAPD analysis. Ther efore, we suggest that these species should be classified into Pinnata e. Also, RAPD analysis was successfully applied to deduce putative par ents for six unknown hybrid lines.
