Resumo: | Five progeny tests with half-sibs Eucalyptus urophylla S. T. Blake were evaluated. Four 4 of them were from provenances Indonesia and one of them from Brazil. It was used the REML/ BLUP (restricted maximum likelihood / best linear unbiased prediction) procedures and the minimum square method for the estimation of genetic values. The tests were established separately according to the origin, in a complete randomized block design, with five replications and row plots of six plants in 3.0 x 2.0 meter spacing in Guanhães, Minas Gerais State. When the plants were 58 months-old for the characteristics of diameter at breast height (DAP), the five evaluated tests showed standard species values, besides presenting significant genetic variability by the F test at 1% of probability. The coefficients of additive genetic variation presented greater values in the TP-71 test from Wetar and TP-68 from Alor, and presented similar values in other tests for the diameter at breast height (DAP) characteristic. Selection gains were estimated at values of 12.8; 22.9; 9.5; 21.0 and 25.3%, and the effective population size (Ne) at values of 60.2; 58.0; 131.8; 167.9 and 224.1 for the TP-67, TP-68, TP-69, TP-70 and TP-71 tests, respectively. A selection gain of 26.8 % was obtained in the clonal seed orchard with selection of 21 plants that were carriers of the greatest additive genetic values. In both procedures, the values of the genetic parameters were similar, except among families, in which the REML procedure em obtained higher values with accuracy higher than 70% in all populations, proving to be appropriate for this purpose. |

T. Blake procedentes da Indonésia, com o uso dos procedimentos REML/BLUP (máxima verossimilhaça restrita/melhor predição linear não-viesada) e pelo método dos quadrados mínimos E (QM). Os ensaios foram estabelecidos separadamente por procedência, sendo o delineamento experimental em blocos casualizados, com cinco repetições e parcelas lineares de seis plantas, no espaçamento 3,0 x 2,0 metros, em Guanhães, MG. Nos cinco testes avaliados aos 58 meses de idade, para a característica diâmetro à altura do peito (DAP), apresentaram valores dentro dos padrões da espécie, além de exibir variabilidade genética significativa, pelo teste F a 1% de probabilidade. Os coeficientes de variação genética aditiva apresentaram valores maiores no teste TP-71 originado de Wetar e no TP-68 originado de Alor, e nos outros testes apresentaram valores similares para a característica diâmetro à altura do peito (DAP). Os ganhos de seleção foram estimados na ordem de 12,8; 22,9; 9,5; 21,0 e 25,3% e tamanho efetivo populacional (Ne) na ordem de 60,2; 58,0; 131,8; 167,9 e 224,1 para ao testes TP-67, TP-68, TP-69, TP-70 e TP-71 respectivamente. O ganho de seleção no Pomar de Sementes Clonal (PSC) foi de 26,8 % com a seleção dos 21 indivíduos portadores dos maiores valores genéticos aditivos. Nos dois procedimentos, máxima verossimilhança restrita (REML) e esperança de quadrados mínimos E(QM), os valores dos parâmetros genéticos foram semelhantes, exceto entre familias, em que o procedimento REML proporcionou valores mais elevados com acurácia superior a 70% em todas as populações, mostrando-se como ferramenta apropriada para esse fim.Universidade Federal de Santa Maria2006-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/191810.5902/198050981918Ciência Florestal; Vol. 16 No. 4 (2006); 369-379Ciência Florestal; v. 16 n. 4 (2006); 369-3791980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1918/1160Rocha, Maria das Graças de BarrosPires, Ismael EleotérioXavier, AloisioCruz, Cosme DamiãoRocha, Rodrigo Barrosinfo:eu-repo/semantics/openAccess2017-05-15T11:26:51Zoai:ojs.pkp.sfu.ca:article/1918Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T11:26:51Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
