The aim of this work was to select progenies with high adaptability and stability from the dry rubber yield (PBS), of genotypes from a three-year-old rubber tree population, installed in three different locations (Selvíria, MS, Votuporanga, SP and Colina, SP), by the MHPRVG (Harmonic mean of the relative performance of the genetic value) method predicted by BLUP. The progenies were installed in a randomized block design with 30 treatments (progenies), three replications and 10 plants per plot, with spacing of 3.00 x 3.00 m (Selvíria, MS) and 1.50 x 1.50 m (Colina, SP and Votuporanga, SP). The PBS presented considerable genetic coefficient variability, ranging from 23.03 to 27.82% and average heritability ranging from 0.47 to 0.99, indicating the high value of the progeny tests in rubber tree breeding programs. The MHPRVG method provided a genetic gain ranging from 11 to 38% in 10 progenies to the PBS and allowed the selection of progenies with high predicted yield potential. |
