SILVA, Ana Veruska Cruz da and MARTINS, Antonio Baldo Geraldo. Identification of molecular markers associated to the absence of seeds in grapevine. Cienc. Rural [online]. 2006, vol.36, n.3, pp. 801-806. ISSN 1678-4596. http://dx.doi.org/10.1590/S0103-84782006000300012.
Seedless has been an important characteristic of table grapes required by consumers. The objective was to identify molecular markers associated to seedless, by RAPD and fAFLP techniques with young leaves samples of 19 cultivars. Thirty primers were used for RAPD analysis, producing a total of 337 polymorphic bands. It was also to find a specific mark for seedless, using UBC 443 primer. This mark would be transformed in a scar marker, making possible the early identification of seedless grape possible. The fAFLP analysis provided a visualization of a dendrogram with specific groups, separated in three different cultivars: with seeds, without seeds and the rootstocks.
