Abstract

The objective of this work was to describe and compare the patterns of genetic variation in 19 populations of Anacardium humile from the Cerrado biome of the Brazilian Midwestern region. The ex situ germplasm collection of Universidade Federal de Jataí, in the state of Goiás, Brazil, was used for the study. To quantify the genetic variability of A. humile, 529 plants from 17 populations in Goiás from 2 in the state of Mato Grosso were studied, from which nine microsatellite loci were genotyped by capillary electrophoresis. The populations showed high levels of genetic diversity, with an average value of 0.830, and high inbreeding values, which suggests a deficit of heterozygotes. The genetic differentiation value between populations was 0.065. The greatest variability, which is moderately structured, was observed within populations. There is a significant inbreeding within the A. humile population in the Cerrado biome of the Brazilian Midwestern region. The A. humile populations are divided into two groups.
