Presentation of the Unit and context within the syllabus

This Unit introduces infrastructure needed for field and indoor platform phenomics. Then specific experimental designs and corresponding mixed models treated in detail together with spatial and longitudinal modelling. Statistical and machine learning techniques presented for pre-processing of phenomic data. Methodologies for the identification of the genetic basis of new phenotypic traits demonstrated. Finally, phenomic traits integrated in prediction models for yield. Examples and exercises used real data from phenotyping platforms and field experiments.

Learning activity 3: Tutored group work
Students, guided by the tutor, work in groups of 5-6 persons. They receive a set of papers on genomic prediction and each group has to select three of them. Every group must draft a synthesis document for public presentation and joint discussion.
ECTS: 1,5
Hours: 37.5
Percentage of contact: 28%

Assessment methods

Assessment system: Presentation a group work related with the interpretation of three papers on genomic prediction. The score is based both on the PowerPoint document and on the presentation and defence of the work. The score is the same for all members of the group.
Weighting: 100% of the final score of the Unit
