Avaliação genética de indivíduos de erva-mate (Ilex paraguariensis St. Hil.) na região de Caarapó, MS, pelo procedimento reml/blup

Abstract

The objective of this paper was to estimate genetic values and parameters for the traits height and diameter of erva-mate individuals using the methodology of mixing models (REML/BLUP procedure). The half-sib progenies were established at the Indigenous Reserve Kaiowá and Guarani, in Caarapó/MS, in a randomized block design, with six treatments, six replications and twenty plants per plot. Nine months after planting, height and diameter were evaluated. Genetic gain predition of 4.16% for height and of 7.20% for diameter were obtained with selection of the best ten individuals. Although the genetic gain is not high for the evaluated age, it stimulate the use of these germoplasms in future evaluations at advanced ages, exploring the variability within progenies.
