Resumo: Dipteryx alata Vogel (“baru tree”) is a fruit species native to the Brazilian Cerrado and presents a multiplicity of uses, constituting a priority species for domestication and cultivation studies. The objective of the current study was to characterize fruit and seeds of D. alata from several regions of the Brazilian Cerrado biome to support strategies for ex situ conservation and utilization of the genetic variability of the species. Fruits were collected from 25 subpopulations, sampling six mother plants per subpopulation, with collection of at least 25 fruits per plant. The physical trait data of the fruits and seeds were submitted to descriptive analysis, analysis of variance and correlation among traits. There was significant variation for all traits among subpopulations and among individuals within subpopulations. The highest proportion of variability was observed among individuals within subpopulations. The phenotypic differentiation among subpopulations was higher for fruit traits compared to seed traits. The correlation analysis showed the existence of significant correlations for most of the traits pairs in the different hierarchical levels. It was concluded that D. alata presents phenotypic variability to support germplasm collection programsand formation of base populations for breeding programs, recommending the sampling in several locations to ensure an adequate representativeness of the phenotypic variability.

(barueiro) é uma espécie frutífera nativa do Cerrado brasileiro e apresenta uma multiplicidade de usos, constituindo-se em espécie prioritária para estudos de domesticação e cultivo. O presente trabalho teve como objetivo caracterizar fisicamente frutos e sementes de barueiro provenientes de coleta de germoplasma em diferentes regiões do Cerrado visando, à conservação ex situ e à utilização da variabilidade genética da espécie. Foram coletados frutos de plantas de 25 subpopulações, em seis estados, amostrando seis matrizes por subpopulação, com coleta de, pelo menos, 25 frutos por matriz. Os dados de caracterização física dos frutos e das sementes foram submetidos à análise descritiva, análise de variância e correlação entre caracteres. Houve variação significativa para todas as variáveis avaliadas entre subpopulações e entre matrizes dentro de subpopulações. A maior proporção da variabilidade foi observada entre matrizes dentro de subpopulações. A divergência fenotípica entre subpopulações foi maior para caracteres de frutos em comparação com caracteres de sementes. A análise de correlação demonstrou a existência de correlações significativas para a maioria dos pares de caracteres avaliados nos diferentes níveis hierárquicos. Conclui-se que D. alata possui variabilidade fenotípica para sustentar programas de coleta de germoplasma e formação de populações-base para programas de melhoramento genético, recomendando-se a coleta em múltiplas procedências para assegurar uma adequada representatividade da variabilidade fenotípica.Sociedade Brasileira de Fruticultura2021-06-09T19:23:18Z2021-06-09T19:23:18Z2020-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfMOTA, E.
