Estimates of genetic and phenotypic correlations at three aspen progeny trials for budbreak (BUD), leaf senescence (LS), height (HT) and survival (SURV).

Genetic and phenotypic correlations were estimated using an individual tree model for BUD, LS, and HT for the seedling Trial 02, with half-sib families excluded. For the clonal Trials 03 and 08 we used an individual clone model. Phenotypic correlations of survival with all other traits were based on family means (Trial 02) and clone means (Trials 03 and 08) with standard errors determined through bootstrapping.
