Resumo: Eremanthus erythropappus (DC.) MacLeishis economically appreciated due toits wood and to the extraction of its essential oil, whose active principle is alpha-bisabolol. Despite itseconomic importance, studies about thegenetic breeding of this species remainscarce. The aim of the currentstudy isto determine E. erythropappusseedling emergencerate, genetic parameters, as well asto identify potential open-pollinated progenies of this speciesand their respective matrices. The experiment was set up in tree nursery, based ona completely randomized design, with 22 progenies in four replicates comprising14 plants per plot. Seedlingemergence rate was evaluated30 days after seeding, whereas plantheight (H) and stemdiameter (SD)were measured at 100 days. Statistical analyses were carried out based onthe REML/BLUP method. Three progenies have shownseedling emergence rate lower than50%; thisvalue is considered limiting to seedling productionprocess. Genetic variation was observed among progenies, as well ashigh and positive genetic correlation between H and SD. Thus, it was possible identifyingsuperior progenies and matrices,as well as the ones presentinglow performance in the evaluated traits.

Eremanthus erythropappus(DC.) MacLeishé uma espécie nativa, apreciada economicamente devido a sua madeira e à extração de óleo essencial, cujo princípio ativo é o alfabisabolol. Apesar da importância econômica, os estudos em melhoramento genético dessa espécie ainda são escassos. Objetivou-se determinar o percentual de emergência, parâmetros genéticos e identificar potenciais progênies de polinização aberta de E. erythropappus e suas respectivas matrizes. O experimento foi implantado em viveiro, em delineamento experimental inteiramente ao acaso, com 22 progênies em quatro repetições, contendo 14 mudas por parcela. Aos 30 dias após a semeadura foi avaliado o percentual de emergência, enquanto aos 100 dias foram realizadas mensurações para altura (A) e diâmetro do coleto (DC). As análises estatísticas foram realizadas por meio do método REML/BLUP. Três progênies apresentaram percentual de emergência abaixo de 50%, valor considerado limitante para o processo de produção de mudas. Verificou-se a existência de variação genética entre as progênies e correlação genética alta e positiva entre A e DC. Dessa forma, foi possível identificar progênies e matrizes superiores bem como aquelas com baixo desempenho nas características avaliadas.Universidade Federal do Paraná2022-01-25T20:27:47Z2022-01-25T20:27:47Z2021info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfAVELAR, M.
