| Abstract: | Mangifera odorata Griff. (Anacardiaceae), was suggested to be a hybrid between M. indica L. and M. foetida Lour. due to morphological intermediacy. Results from this study show that M. indica and M. foetida produced unique amplified fragment length polymorphism (AFLP) profiles. Mangifera odorata did not produce any unique bands. All the M. odorata samples additively inherit bands specific to M. indica and M. foetida, which strongly suggested the hybrid origin. Three major clusters were produced in the phenogram. All samples of M. indica, M. foetida and M. odorata segregated distinctly. Mangifera odorata was closer to M. foetida than to M. indica, indicating that backcrossing with M. foetida might have taken place. AFLP analysis therefore verified the hybrid status of M. odorata. |
