This paper aimed to select progenies of "erva-mate" (Ilex paraguariensis St. HiI.) in Ivai - PR based on leaf weight productivity, stability and adaptability across three harvests. This can be achieved by the method MHPRVG (harmonic average of relative performance of genetic values) which is comparable with the methods by Annichiaricco and Lin & Binns. The genetic material was constituted by 25 half sib progenies evaluated in a complete block design with ten replicates and six plants per plot, in a 3 x 2 meters spacing. Leaf weight per tree was evaluated at ages two, four and six years after planting. There were some changes in progenies ranking across harvests. The methods MHPRVG, Annichiaricco and Lin & Binns led to selection of the same progenies, considering the three attributes simultaneously. However, the MHPRVG method presented the advantage of providing results in the scale of the measured trait, which can be interpreted directly as genetic values.Downloads
