Resumo: | Sacha inchi (Plukenetia volubilis L.) is a species with nutraceutical benefits traditionally consumed by Amazonic indigenous and urban communities. Studies on the genetic diversity and mating system are required to preserve and make the best use of the genetic resources for this species. This study aimed to estimate the genetic diversity and mating system parameters of sacha inchi progenies using Amplified Fragment Length Polymorphism (AFLP) markers. A total of 360 progenies from 30 accessions of sacha inchi were analyzed using three AFLP primers combinations. The percentage variation between and within families and the crossing rate, among other parameters, were estimated. The AFLP markers were efficient in genetically differentiating progenies, revealing 251 (98.82 %) polymorphic fragments. The analysis of molecular variance showed that the strongest variation occurs between progenies (57.16 %). However, the genetic differentiation within progenies was considerable (42.84 %), and could be exploited in breeding programs. The estimated population outcrossing rate was high (0.957), indicating it is a predominantly allogamous species. On the other hand, 33.7 % of the crosses occurred between related individuals. The estimate for biparental crosses revealed that the progenies consisted mainly of half-siblings (66.9 %) and full-siblings (28.8 %). For purposes of breeding and ex situ genetic conservation, sacha inchi seeds should be collected from a large number of parent plants. |

Estudos de diversidade genética e do sistema reprodutivo são necessários para a conservação e uso dos recursos genéticos da espécie. Objetivou-se estimar parâmetros de diversidade genética e do sistema reprodutivo de sacha inchi, utilizando-se marcadores Amplified Fragment Length Polymorphism (AFLP). Um total de 360 progênies de 30 subamostras da espécie foram analisadas, com três combinações de primers AFL. Foram estimadas, dentre outros parâmetros, a porcentagem de variação entre e dentro de famílias e a taxa de cruzamento. Os marcadores AFLP foram eficientes na diferenciação genética das progênies, revelando 251 (98,82 %) fragmentos polimórficos. A análise de variância molecular mostrou que a maior parte da variação ocorre entre famílias (57,16 %). No entanto, a diferenciação genética dentro destas foi considerável (42,84 %), podendo ser explorada em programas de melhoramento. A estimativa da taxa de cruzamento multiloco foi alta (0,957), indicando se tratar de uma espécie predominantemente alógama. Por outro lado, 33,7 % dos cruzamentos ocorreram entre indivíduos aparentados. A estimativa para cruzamentos biparentais revelou que as progênies são constituídas principalmente por meios-irmãos (66,9 %) e irmãos-completos (28,8 %). Para fins de melhoramento e conservação genética ex situ, sementes de sacha inchi devem ser coletadas de um grande número de plantas matrizes.Escola de Agronomia - Universidade Federal de Goiás2018-01-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/49799Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 4, Oct./Dec. 2017; 480-487Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 4, out./dez. 2017; 480-487Pesquisa Agropecuária Tropical; v. 47, n. 4, out./dez. 2017; 480-4871983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/49799/25094Copyright (c) 2018 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessValente, Mágno Sávio FerreiraLopes, Maria Teresa GomesChaves, Francisco Célio MaiaPantoja, Mozanil CorreiaSousa, Francy Mary GalúcioChagas, Edvan Alves2020-07-13T18:56:30Zoai:ojs.revistas.ufg.br:article/49799Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:18.709608Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
