Development of Crop Ideotypes

A.Y. 2019/2020
Overall hours
Learning objectives
Objective of the course is to provide students with knowledge of multidisciplinary approaches to design and breed new crop ideotypes to improve quantity, quality, efficiency and sustainability of agricultural production for different end-uses. Integrating genetics, genomics and modeling, the course is centered on ideotype breeding with special focus on cereals and other cultivated plants as case studies.

Knowledge of the principles of ideotype breeding. Understanding of genetic and molecular mechanisms controlling plant architecture and development and how their manipulation can be applied to crop breeding. Connecting understanding of plant gene function and genetic diversity to traits and field performance. Use of biophysical models to design ideotypes targeting current climate and future projections.
