| Based on nine microsatellite loci, the aim of this study was to appraise the genetic diversity of 42 cassava ( Manihot esculenta ) landraces from selected regions in Brazil, and examine how this variety is distributed according to origin in several municipalities in the states of Minas Gerais, São Paulo, Mato Grosso do Sul, Amazonas and Mato Grosso. High diversity values were found among the five above-mentioned regions, with 3.3 alleles per locus on an average, a high percentage of polymorphic loci varying from 88.8% to 100%, an average of 0.265 for observed heterozygosity and 0.570 for gene diversity. Most genetic diversity was concentrated within the regions themselves ( H S = 0.52). Cluster analysis and principal component based scatter plotting... |
