Resumo: | Parkia platycephala, known commonly as faveira, is a native species that occurs widely throughout Brazil and has high nutritional value and ecological potential. The objective of this study was to estimate the genetic variability in a P. platycephala provenance and progeny test. The test was established using a randomized block design, with 45 progenies from three provenances. The evaluated quantitative traits included height (HEI), diameter at ground level (DGL), and diameter below the first bifurcation (DFB). The data were submitted to Restricted Maximum Likelihood/Best Linear Unbiased Prediction (REML/BLUP) analysis, from which estimates of genetic parameters, genetic correlations, BLUPs, genetic gains, and effective population size were obtained. Estimates of individual narrow sense heritability (h2a) and within progeny heritability (h2w) ranged from low to moderate (0.01 a 0.39), with the highest values observed for DGL (0.32 and 0.39, respectively). The coefficient of individual variation (CVgi(%)) and between progeny genetic variation (CVgp(%)) indicate the existence of genetic variability between and within provenances. The FST vaues demonstrate low to moderate genetic differentiation among the three populations, and genetic correlations between traits were all positive and significant. The results obtained show that there is genetic variability between the studied provenances and progenies. This ensures not only the ex situ conservation of the species, but it can also be exploited in breeding programs. |

Objetivou-se com o trabalho estimar a variabilidade genética em teste de procedências e progênies de P. platycephala. O teste foi instalado em blocos casualizados, com 45 progênies de três procedências. Os caracteres quantitativos avaliados foram: altura (ALT), diâmetro a nível do solo (DNS) e diâmetro a altura da primeira bifurcação (DAB) das plantas. Os dados foram submetidos à análise de REML/BLUP, a partir da qual foram obtidas as estimativas de parâmetros genéticos, correlações genéticas, os BLUP’s, ganhos genéticos e tamanho efetivo populacional. As estimativas de herdabilidade individual no sentido restrito (h2a) e dentro progênies (h2w) variaram de baixa a moderada (0,01 a 0,39), sendo os maiores valores observados para o caractere DNS (0,32 e 0,39, respectivamente). Os valores de coeficiente de variação genética individual (CVgi(%)) e entre progênies (CVgp(%)) indicam existência de variabilidade genética entre e dentro de população. Os valores de demonstraram baixa a moderada diferenciação genética entre as três populações. As correlações genéticas entre os caracteres foram todas positivas e significativas. Os resultados obtidos mostram que há variabilidade genética entre as procedências e progênies estudadas. Isso garante não só a conservação ex situ da espécie, como também pode ser explorada em programas de melhoramento.Universidade Federal de Santa Maria2023-03-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6405810.5902/1980509864058Ciência Florestal; Vol. 33 No. 1 (2023): Publicação Contínua; e64058 Ciência Florestal; v. 33 n. 1 (2023): Publicação Contínua; e64058 1980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/cienciaflorestal/article/view/64058/51866Copyright (c) 2023 Ciência Florestalhttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessSilva, Dandara Yasmim Bonfim de OliveiraFarias, Séfora Gil Gomes deResende, Rafael TassinariCardoso, Clarice RibeiroSilva, Romário Bezerra eTambarussi, Evandro Vagner2023-06-07T17:41:26Zoai:ojs.pkp.sfu.ca:article/64058Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2023-06-07T17:41:26Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
