Description

The present study had the objective of analyze the GxE effects in clonal tests of loblolly pine implanted in the South and Southeast regions of Brazil. For this, 75 clones and three commercial controls were tested using randomized block design, with eight replicates and one plant per plot repeated in four sites. Measurements were performed at 11 years of age and the evaluated traits were: diameter at breast height (dbh), total height and volume. The GGE biplot and the Harmonic Mean of the Relative Performance of Genotypic Values (MHPRVG) methods were used to study GxE effects.
