Parâmetros genéticos para caracteres de crescimento inicial em progênies de bracatinga

Abstract

Objetivou-se com este trabalho estimar parâmetros e valores genéticos para os caracteres diâmetro do coleto e altura de progênies de bracatinga em fase inicial de desenvolvimento. 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.
