Última Development of a Brazilian maize core collection Genet. Mol. Biol. Coimbra,Ronaldo R.; Miranda,Glauco V.; Cruz,Cosme D.; Silva,Derly J.H.; Vilela,Ramiro A.. The aim of this study was to evaluate methods for developing a Brazilian maize core collection. For an initial survey of the active collection, passport information, as well as characterization and evaluation of accessions, were taken into consideration, these then being divided according to geographic region and kernel-type. Multiple sampling methods were evaluated. The strategy of constant sampling generated extensive alterations in extract accession frequency. The multivariate strategy with dispersion graphs and principal components associated with the Tocher method was considered efficient for identifying the most divergent genotypes. The multivariate strategy generated greater alterations in the variance of traits. The average number of traits...
