Use of microsatellite markers to assess the identity and genetic diversity of vitis labrusca and vitis rotundifolia cultivars/Uso de marcadores microssatelites para acessar a identidade e diversidade genetica de cultivares de vitis labrusca e vitis rotundifolia

Ten grapevine cultivars were genotyped at eight microsatellite loci to characterize their identity and genetic diversity. Of these, nine cultivar profiles matched with those of databases and 'Magoon' matched with 'Regale' in the present study and 'Regale' in the Univers...

description Ten grapevine cultivars were genotyped at eight microsatellite loci to characterize their identity and genetic diversity. Of these, nine cultivar profiles matched with those of databases and 'Magoon' matched with 'Regale' in the present study and 'Regale' in the University of California (Davis) database, implicating a likely error in planting. The number of alleles ranged from 5 (VVM5) to 9 (VVMD31), and the observed heterozygosity ranged from 37.14 (VVMD5) to 97.14% (VVMD27), with no significant differences in relation to the expected values for any of the loci, with the exception of VVMD5. The polymorphism information content values were observed to be above 0.25 in more than 85% of the loci analyzed, and VVMD31 was the most informative. The UPGMA analysis clustered the cultivars into two distinct groups. Within each group, the most divergent cultivars were 'Bountiful' (V. rotundifolia) and 'Goethe' (V. labrusca), also exhibiting the largest number of private alleles, 4 and 7, respectively. When comparing the two groups, the most divergent accessions were 'Bountiful' and 'Bordo', with the highest Nei distance. It was demonstrated that there is sufficient genetic variability in the cultivars used in this study to support breeding programs. Keywords: grapevine, genetic variability, molecular marker. Dez cultivares de videira foram genotipadas com oito locos microssatelites a fim de confirmar a sua identidade e caracterizar sua diversidade genetica. Destas, o perfil de nove cultivares foram identicos aos da base de dados e o de 'Magoon' foi identico a 'Regale' deste estudo e de 'Regale' da base de dados da Universidade da California (Davis), indicando um provavel erro de plantio. O numero de alelos variou de 5 (VVM5) a 9 (VVMD31). A heterozigosidade observada variou de 37,14 (VVMD5) a 97,14% (VVMD27), sem diferencas significativas em relacao aos valores esperados para todos os locos, exceto para VVMD5. Os valores de conteudo de informacao polimorfica (PIC) foram superiores a 0,25 em mais de 85% dos locos analisados, sendo que VVMD31 apresentou-se como o mais informativo. Por meio da analise de agrupamento UPGMA foi possivel separar as cultivares em 2 grupos distintos. Dentro de cada grupo, as cultivares mais divergentes foram 'Bountiful' (V. rotundifolia) e 'Goethe' (V. labrusca), que tambem apresentaram o maior numero de alelos privados, 4 e 7, respectivamente.
