Parentage of grapevine rootstock 'Fercal' finally elucidated
Résumé
Using a set of 20 microsatellite markers, 'B.C. n degrees 1B' (mother) and '31 Richter' (father) were demonstrated to be the true parents of 'Fercal' rootstock. '333 Ecole de Montpellier' was definitively excluded as the putative father. 'B.C. n degrees 1A' and 'B.C. n degrees 1B' were shown to be distinct genotypes. 'Ugni blanc', and not 'Colombard', was discovered to be the Pais vinifera father of 'B.C. n degrees 1B'.
