Abstract

Abstract: RAPD ( random amplified polymorphic DNA) variation was assessed in 65 accessions of jackfruit (Artocarpus heterophyllus Lam. ) from Leizhou peninsula, southern China. Among 78 bands detected by 16 RAPD p rimers, 69 were polymorphic. The cluster analysis showed that three group s could be clustered
when genetic distance coefficient was given as 0.26. In contrast to high diversity among morphology characters, high average genetic similarity coefficient was observed (0.7431) on RAPD markers. Soft type and firm type could not form an independent cluster, nor the germplasm introduced from Malaysian species. The classification methods and the introduction strategy of jackfruit germplasm were discussed.

Key words: Jackfruit, Genetic diversity, Germplasm resources, RAPD
