Última Microsatellite polymorphism in wheat from Brazilian cultivars; inter- and intra-varietal studies Genet. Mol. Biol. Lima,Vitor Lopes de Abreu; Seki,Homiko Abreu; Rumjanek,Franklin David. Eleven samples of wheat (Triticum aestivum) from different Brazilian cultivars and six American varieties were compared for polymorphism, using primers for nine different STR loci. STR analysis of DNA from single grains of the Brazilian varieties showed that for most loci there was very little intra-cultivar polymorphism. The polymorphic variation observed for Brazilian cultivars was similar to that seen in the American varieties. For the Brazilian cultivars PCR analysis could be performed on only one half of a grain. The American samples required more seeds for analysis. The nucleotide sequences of five amplified microsatellites selected at random from the Brazilian samples were also determined and compared to those of the Chinese Spring variety. Although...
