Resumo: | http://dx.doi.org/10.5902/198050985733Sphaeropsis sapinea is an important pathogen for some Pinus radiata causing tip blight and death of trees, in commercial plantings. This study was developed to select Pinus radiata progenies resistant to the pathogen, for new plantings in Brazil. Seedlings tips of 16 Pinus radiata progenies were inoculated with three pathogen monosporic isolates of Sphaeropsis sapinea, under greenhouse conditions. Lesions length and tip blight degree were evaluated. Responses of progenies to the pathogen varied according to tested isolate. The results indicated that early selection methodology was adequate to select Pinus radiata progenies resistant against Sphaeropsis sapinea. Average heritability of the progenies varied according to tested isolate and the selection criterion used. |

Este estudo teve como objetivo selecionar progênies de Pinus radiata resistentes ao patógeno. Mudas de 16 progênies de Pinus radiata foram inoculadas com três isolados monospóricos do patógeno, em condição de casa de vegetação. Foram avaliados o comprimento das lesões e o grau de secamento dos ponteiros. Os resultados indicaram que a metodologia de seleção precoce foi adequada para selecionar progênies de Pinus radiata resistentes ao Sphaeropsis sapinea. A herdabilidade média das progênies variou de acordo com o isolado testado e o critério de seleção utilizado.Universidade Federal de Santa Maria2012-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/573410.5902/198050985734Ciência Florestal; Vol. 22 No. 2 (2012); 257-281Ciência Florestal; v. 22 n. 2 (2012); 257-2811980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/5734/3515Corrêa, Paula Rachel RabeloAuer, Celso GarciaSantos, Alvaro Figueredo dosHiga, Antonio Rioyeiinfo:eu-repo/semantics/openAccess2014-08-26T00:22:52Zoai:ojs.pkp.sfu.ca:article/5734Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2014-08-26T00:22:52Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
