D1: The Vine: Background: Ernst Ruhl from Geisenheim on Vine Breeding
Professor Ernst Ruhl from the Geisenheim Grape Breeding Institute explains how vines are bred in this second interview.
We hear how vines reproduce and how different breeds are crossed with each other. We also talk about clones and clone selection and how, through their breeding programme, Geisenheim are protecting the genetic diversity of grape vines.
I thought the questions were excellent, an extremely valuable revision tool. They really helped highlight areas I thought I had revised and understood but clearly had not, which has enabled me to focus on key areas to revisit and study before going into the exam... I think it is a great resource and an essential revision aid for any WSET 3 students wishing to gain a competitive edge and successfully pass the WSET 3 exam.
