Resumo: This study aimed at verifying the efficiency of early selection, and estimating the genetic parameters in Dipteryx alata. The 66 half-sib families were obtained from three seed provenances at the Brazilian Savannah of the state of Minas Gerais. The experiment was carried out in a randomized block design with 3 replications and 5 plants per plot. Data diameters at breast height (DBH) and total height (TH) were taken at the ages of 64, 125 and 138 months. REML/BLUP methodology was applied in the D. alata different provenances and progenies. Analysis indicated significant genetic variability (P < 0.01) between and within provenances. Both traits, DBH and TH, presented high narrow sense heritability for the ages analyzed. High genetic correlation occurred between DBH and TH traits, and between ages (age-age); thus, it allowed indirect selection, as well as early selection with high genetics gains.

Foram avaliadas 66 famílias de meio-irmãos, de três procedências no delineamento de blocos ao acaso com três repetições e cinco plantas por parcela. Foram obtidos os dados de diâmetro à altura do peito (DAP) e altura total aos 64, 125 e 138 meses de idade. Obtiveram-se, para ambas as características, as estimativas dos parâmetros genéticos via metodologia de REML/BLUP. Verificou-se a existência de variabilidade genética significativa entre e dentro das procedências. Observou-se alta correlação genética entre DAP e altura total e entre as idades (idade-idade), possibilitando assim a seleção indireta e seleção precoce com significativos ganhos.Sociedade Brasileira de Melhoramento de Plantas (SBMP)2020-11-29T03:21:39Z2020-11-29T03:21:39Z2014-12info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSANTOS, A.
