- Isozymes are used as markers to compare the genetic variability of seeds collected in three states of the natural rubber region with cultivated clones (Wickham collection). Genetic distances and factor analysis show a significant difference between Acre and Mato Grosso on the one hand and Rondonia on the other. A marked homogeneity appears between Acre and Mata Grosso, Rondonia is more heterogeneous because one of the districts resembles Mato Grosso and the others resemble AcreIsozymes are used as markers to compare the genetic variability of seeds collected in three states of the natural rubber region with cultivated clones (Wickham collection).
