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

2005

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