Learning Outcomes

On successful completion of this module students should be able to:

1. Demonstrate an understanding of the basis of crop adaptation to different environments and management practices.

2. Discuss the bases of tolerance to various abiotic and biotic stresses.

3. Evaluate the traits required to select for yield stability, and the relationship between yield potential and yield stability.

4. Be able to assess, analyse and interpret a genetic x environment or management experiment showing a clear understanding of the meaning and importance of statistical interactions.

Brief description

Students will be provided with an understanding as to why the yield and quality performance of crop varieties interact with crop management and environment. Approaches to reduce instability in performance will be presented and the importance of crop adaptation will be explained.

Content

Students will be provided with an understanding, first of the traits targeted to maximise yield potential and quality, but then also of the traits that underpin adaptation and stability, i.e. an understanding of Genetic x Environment (G x E) and Genetic x Management interactions (G x M). For G x E, students will develop an understanding of: the roles of photoperiod sensitivity, earliness, and vernalization for crop adaptation; sources and traits for cold, heat and drought tolerance; tolerance of salinity and acidity; and the traits required for certain ecosystem services. For G x M, the students will understand the interactions between agronomic factors and variety performance and suitability including: sowing date and conditions; crop nutrition; crop protection; and harvest and rotational requirements.
In addition to a programme of lectures, students will also assess, analyse and interpret a genetic x environment or management experiment and will be provided with the techniques to evaluate interactions.
