Requisites and permanence
There are no previous requisites
Combination of theoretical and practical classes, and individual study and work.
Lecturers may deliver the topics in Spanish or in English. In the second case, simultaneous interpretation into Spanish is provided. The documents supplied by the lecturers may also be written in Spanish or in English.
Presentation of the Unit and context within the syllabus
The unit is divided in two parts: Objectives, principles and processes in plant breeding and Plant genetics and variability. In the first part of the unit, the evolution of plant breeding is reviewed from a historical perspective. Then the objectives, processes and determining factors of plant breeding are explored, including time, heritability and the nature of the final product. Examples of public and private modern plant breeding programmes are introduced, considering their socioeconomic, agronomic and environmental context. In the second part of the unit, the principles of plant genetics and molecular biology are dealt with. The final part of the unit is devoted to the study of the safeguarding and use of plant genetic resources, through the study of material collections, their conservation, multiplication and documentation, as well as of database management and sample exchanges.
- SC1 Mastering the basics and principles of modern plant breeding, including new quantitative and molecular tools like genomics and, in general, the knowledge and application of '-omics' technologies.
- SC2 Identifying and assessing phenotypic and genetic variability and determining the components of variation.
- SC3 Assessing the importance of genetic resources as variability sources in breeding programmes, and commanding the appropriate processes for their collection, conservation, evaluation and use.
- GC1 Integrating scientific and technical knowledge and applying them discerningly.
- GC5 Learning and working autonomously, responding to unforeseen situations and re-aiming a strategy if necessary.
- GC7 Communicating reasoning and conclusions both to a general audience and to a specialized public.
At the end of Unit 1, the student:
- Analyzes the historical evolution of plant breeding, knowing which have been the key scientific and technical advances that have influenced its development or accelerated its results.
- Knows the different plant reproduction systems, how they affect genetic variability and how they condition the strategies and processes of selection and breeding.
- Has a deeper insight into the genetic basis supporting plant breeding, from the individual gene to the complete genome.
- Knows the aim of the genome analysis projects of certain model plant species and the possibilities offered by their comparison with the genomes of other species of agronomic interest.
- Understands the importance of identifying genes, isolating them, determining their function and controlling their expression.
- Can identify genetic variability, locating the genetic regions associated with traits of interest for breeding, and determining the connection between phenotypic and genetic variability.
- Considers the importance of plant genetic resources as a source of variability in plant breeding programmes, and knows the appropriate processes for their collection, conservation, evaluation and use.

Learning activity 1: Lectures combined with case studies
Percentage of contact: 39%
Learning activity 2: Practical sessions with solving of exercises and problems on Mendelian genetics and biometrics.
Percentage of contact: 43%
Assessment system 1: Written exams, composed by questions provided by the different lecturers of the Unit.
The questions are either multiple choice or concrete questions requiring a short development. The exam assesses the content of lectures as well as the understanding of the practicals, through exercises similar to those developed during the practical sessions.
In the written exam, the questions which are not multiple choice are marked according to the technical and conceptual precision of the answer, and to the reasoning approach, and the exercises according to the understanding of the methodology and the validity of the results.
Weighting: 80% of the final score of the Unit
Assessment system 2: Global assessment of the solving of exercises and problems by the lecturer in charge of them. Understanding of the methodology and quality of the results will be assessed.
Weighting: 20% of the final score of the Unit
