Fine-scale Genetic Structure of Eucalyptus globulus ssp. globulus Forest Revealed by RAPDs

S. Skabo, R. E. Vaillancourt and B. M. Potts

Australian Journal of Botany 46(6) 583 - 594
Published: 1998


Fine-scale genetic structure in Eucalyptus globulus ssp. globulus native forest was detected using 69 randomly amplified polymorphic DNA (RAPD) markers. The association between genetic similarity and geographic distance was studied among 51 trees from the Tinderbox locality in Tasmania (distance ranging from 2 m to 4 km apart) and compared to 18 trees from localities up to 100 km away. Twenty pedigreed F1s were used as controls to scale the RAPD similarity among individuals to pedigree similarity. The association between genetic similarity and geographic distance was weak, yet at Tinderbox, highly related trees were shown to occur within 25 m of one another. There is an abrupt drop in average similarity after about 25 m, with no significant change with distances up to 14 km. Nevertheless, Tinderbox trees outside the 25 m genetic patches are still more similar to each other than they are to trees from the Mayfield Bay locality 100 km away. These results suggest that E. globulus native forests have a family group structure, superimposed on a noisy, background level of lower relatedness which extends over a wider geographical range. This study is unique in demonstrating the congruence between fine-scale genetic structure as revealed by molecular data and previous quantitative genetic data.
