Description

The main goal of this work was to estimate genetic parameters, environmental x genotype interaction and genetic gain on selection in two progeny tests of Cordia trichotoma. The experimental design was lead in randomized complete block, one tree plot with 40 and 34 replicates, 3.0x 3.0 m spacing between C. trichotoma and Dalbergia nigra and 6.0 x 6.0 m between C. trichotoma plants. C. trichotoma progenies, in a total of 30, were consorted with 30 Dalbergia nigra progenies o from the same place. The diameter at breath height (1.30 m), plants height, diameter at 30 cm from the soil, first twig height and survival were evaluated. The REML/BLUP method was used. Significant differences (p<0.01) were observed between progenies for the whole quantitative traits.
