Cross-hybridizations between Glebionis coronalia (L.) Spach and G. segetum (L.) Fourr., G. coronalia and Leucanthemum vulgare Lam. and G. segetum and L. vulgare by using ovule culture were successfully made the hybrid seedlings. RAPD primer OPA20 was found to isolate respective bands specific to G. coronalia, G. segetum, and L. vulgare. The F1 hybrids between G. coronalia and L. vulgare and G. segetum and L. vulgare showed morphologically rather the maternal-side leaf characters.
