Grapevine germplasm, including 38 of the main Portuguese cultivars and three foreign cultivars, Pinot Noir, Pinot Blanc and Chasselas, used as a reference, and 37 true-to-type clones from the Alvarinho, Arinto, Loureiro, Moscatel Galego Branco, Trajadura and Vinhão cultivars were studied using AFLP and three retrotransposon-based molecular techniques, IRAP,(More)
A germplasm set of twenty-five grapevine accessions, forming eleven groups of possible berry skin color mutants, were genotyped with twelve microsatellite loci, being eleven of them identified as true color mutants. The polyphenolic profiling of the confirmed mutant cultivars revealed a total of twenty-four polyphenols, comprising non-colored compounds(More)
A familial pericentric inversion of chromosome 8 is described. The break points were localized by a high resolution chromosome banding technique and found to be inv(8)(p23.108q12.100). None of the family members had an unbalanced product of the inversion. There were no phenotypical abnormalities in the carriers. The break points and segregation pattern are(More)
BACKGROUND Genetic diversity is fundamental to breeding programs and consequently has an important role in obtaining new varieties. To properly use the genetic diversity present in germplasm collections, a good knowledge of the agro-morphological traits of each accession is needed. The aim of this study was to explore the production capacity of 24 cowpea(More)
Understanding grape berry development and the metabolism of different classes of compounds responsible for traits like berry's color is imperative to control and improve quality aspects of grapes. A colorimetric, biochemical and molecular characterization allowed the comprehensive description of the pigment-related characteristics of nine berry skin color(More)
Grapevine chloroplast (cp) DNA diversity was analysed for the first time through amplification and digestion of fragments of the large single copy (LSC) region by polymerase chain reaction-restriction fragment length polymorphism methodology and also by amplification of three microsatellite loci, previously described as polymorphic in grapevine.(More)
