Objectives: Analysis of phenotypic and genetic natural variation within Malbec clone collections
Tasks : During the first secondment we will aim to the analysis of: a) phenotypic and b) natural genetic variation within a Malbec clone collection.
- Biochemical, phenological and productive data corresponding to two consecutive seasons will be compared and analyzed to assess the phenotypic differences between the clones.
- Genetic polymorphism data obtained after the NGS re-sequencing of four Malbec will allow the selection of a robust set of 48 SNP markers. By means of these markers we will evaluate the natural genetic variation between a sample of more than 200 different Malbec clones.
Deliverables (expected) :
- A set of 6-8 Malbec clones showing contrasted phenotypic characteristics for climate change adaptation traits (cycle length, colour, acidity, potential alcohol (°Bx). b) a set genetically divergent clonal accessions, putatively associated to the time span of clonal propagation in Argentina and Europe.
