Resumo: The aim of this work was estimate genetic parameters and values in the stem diameter and height in Mimosa scabrella progenies at early stages. Seeds were collected from 40 mother trees in Abelardo Luz, Chapadão do Lageado, Lages and Três Barras, in Santa Catarina State. Progenies test was conducted at the Experimental Farm of the Santa Catarina State University, in Lages, SC, aiming at to select genetic materials adapted for the region. It was used ramdomized blocks, with 40 treatments (progeny) and 30 replications, using 10 plants by plot in single line. At 12 months old height and diameter were evaluated. Deviance analysis was performed using Selegen-REML/BLUP software and genetic parameters were estimated. Significant differences were observed among provenances and progenies. Genetic control of characters is considered low to moderate in individual and family levels. Stem diameter was more appropriate for matrices selection due to its higher variation and genetic control.

As sementes foram coletadas de 40 matrizes nativas nos municípios de Abelardo Luz, Chapadão do Lageado, Lages e Três Barras, SC. O teste de progênie foi conduzido na Fazenda Experimental do Centro de Ciências Agroveterinárias da Universidade do Estado de Santa Catarina, em Lages, visando à seleção de materiais genéticos adaptados ao local. O delineamento utilizado foi o de blocos ao acaso, com quarenta tratamentos (progênies), 30 repetições e dez plantas por parcela em linhas simples. Aos 12 meses de idade, foram avaliados os caracteres: diâmetro do coleto e altura total dos indivíduos. Diferenças significativas foram observadas entre procedências e progênies. Os coeficientes de herdabilidade em nível de indivíduo e de média de progênies, assim como os coeficientes de variação genética foram altos, para os dois caracteres avaliados, e os maiores valores foram encontrados para as procedências de Abelardo Luz e Chapadão do Lageado, indicando um forte controle genético na herança destes caracteres e possibilidade de encontrar indivíduos superiores.Embrapa Florestas2016-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/100310.4336/2016.pfb.36.87.1003Pesquisa Florestal Brasileira; v. 36 n. 87 (2016): jul./set.; 235-243Pesquisa Florestal Brasileira; Vol. 36 No. 87 (2016): jul./set.; 235-2431983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1003/508Copyright (c) 2016 Renata Diane Menegatti, Adelar Mantovani, Márcio Carlos Navroskihttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMenegatti, Renata DianeMantovani, AdelarNavroski, Márcio Carlos2017-04-28T14:13:12Zoai:pfb.cnpf.embrapa.br/pfb:article/1003Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T14:13:12Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
