SELEÇÃO DENTRO DE PROGÊNIES DE POLINIZAÇÃO ABERTA DE Cariniana legalis Mart. O. Ktze (LECYTHIDACEAE), VISANDO À PRODUÇÃO DE SEMENTES PARA RECUPERAÇÃO AMBIENTAL

Abstract: A baixa diversidade genética das espécies em plantio de restauração tem sido apontada como uma limitação ao sucesso destes plantios. O principal objetivo deste estudo foi determinar um esquema mais adequado de seleção dentro de um teste de procedências e progênies de Cariniana legalis (jequitibá-rosa), aos 26 anos de idade, estabelecido em Luiz Antônio, São Paulo, para fins de produção de sementes para recuperação ambiental. O teste foi implantado no delineamento experimental de blocos de famílias compactas, c… Show more

“…The effective population size (N e ) after selection was estimated as N e = 0.5/Θ, where Θ is the group coancestry (Lindgren et al 1996), estimated by Θ =[mn0.5(1 + F p )+ mθ xy n(n − 1)]/(nm) 2 (Sebbenn et al 2009b), where m and n are the number of selected families and plants within family, respectively; F p is the inbreeding coefficient in the parental population; and θ xy the coancestry between plants within family, assumed as half-sibs (θ xy = 0.125).…”
