Abstract

Likelihood ratio tests (LRT) were applied in an unbalanced provenance/progeny test of mate (Ilex paraguariensis A. St. Hil.). The trial was established in a randomized complete block design with seven provenances, 140 half sib families, ten blocks and six plants per linear plot. The spacing was 3 m x 2 m. The following conclusions were obtained from the deviance analysis (Anadev): all random effects and associated variance components and coefficients of determination (heritability and coefficients of determination of plots and provenances) were significant; there is enough genetic variability in both within and between provenance levels which can be adequately explored for breeding purposes.
