Short description of project
The grapevine genepool is particularly threatened in the marginal areas of its distribution range. At the same time, grapevine genetic resources in the presumed area of its domestication (south-eastern Europe and particularly the Caucasus) and along the migration route across Europe are poorly known while enclosing still untapped diversity and richness. To address this challenge scientists and breeders need to work together at an international level to generate knowledge about the valuable diversity, its patterns, processes and correlations with traits such as resistance and grape quality. This COST Action will enable researchers from east and west European countries to work together to explore, on a large geographic scale and in a very wide range of countries, the genetic diversity and mobilize adaptive traits for breeding and sustainable use of this very valuable horticultural crop. Sharing experiences, responsibilities, information and materials for the development of phenotyping methods and association genetics studies in core collections will greatly improve the impact of the research conducted by each partner and will introduce innovative areas of research at the European level, creating beneficial knowledge, long-term conservation and a greater quality of grape production in Europe.
Short description of the task performed by Croatian partner
Owing to the recent fast development of powerful molecular genetics and genomics tools, researchers working on long-lived species are advancing their methods for understanding genes’ action and value by means of association genetics. These methods, derived essentially from human genetics, allow replacing the slow standard techniques of studying segregation of characters in single progenies from hand-made pollinations in field experiments, to fast tracking the ancestry of molecular diversity in pools of genetic resources, and to analyzing correlations among gene diversity and expression of the traits in the phenotype. The future of grapevine research and breeding is thus based on the constitution of core collections, drawn from the broadest pool of genetic resources, and the development of genotyping, phenotyping and association genetics methodologies. The research fields of importance for further developing and implementing this strategy are: (1) Identification and characterization of the existing genetic resources (2) Development of faster and more precise phenotyping methods (3) Development of molecular tools for high-throughput genotyping (4) Establishment of pools of genetic resources with known levels of diversity and ancestry (5) Research of correlations among genotype and phenotype
