PBR22803 Principles of Plant Breeding (Distance Learning) Teaching methods: 0.5 DT; 0.5 DG; 2.0 DEL Contact person: R.E. Niks (niks001) Lecturer(s): R.E. Niks (niks001) Examiner(s): R.E. Niks (niks001) This course introduces students to key principles of plant breeding. Different subjects are the importance of the mode of reproduction of crops and the genetic consequences for selection. Various selection methods are discussed. For an effective selection programme it is imperative to distinguish genotype from phenotype, since only the genotypic differences are relevant to genetically improve the crop. - understand the advantages and limitations of plant breeding selection programmes - understand the role of mode of reproduction of plants on the genetic composition of crops - analyse genetic segregations - analyse observations to separate genetic and non-genetic components of variation - know the methods and perspectives of modifying genome numbers (ploidy levels) and DNA sequences Activities: The course consists of a number of e-learning modules that explain and illustrate the principles, and give numerous exercises to the student to test his understanding. Feedback on correct and wrong answers is given. Group assignments, self-tests and discussions are other activities in this course. Literature: Recommended: G. Acquaah, 2012.

In addition the participants will have the opportunity to apply the knowledge gained during the course and use their own creativity in the form of an group assignment that will run throughout the course. Another main feature of the course will be to analyse and assess the implications of this new technology for wider society. The assignment will form a central part of the course and will be submitted in the form of a written report and a presentation the latter will be reviewed and evaluated by fellow students. The presentations and debates will form part of practical week at the WUR campus. 1. Understand the scientific and technological components of what is and is not Plant Biotechnology 2.

PBR31802 Breeding for Quality (Distance Learning) Teaching methods: 0.5 DKC; 0.8 DT; 0.2 DG; 0.5 IS Contact person: Dr. AG Bovy Lecturer(s): Dr. AG Bovy; Dr. L. Trindade Examiner(s): Dr. L. Trindade Assumed knowledge: Genetics, principles of plant breeding, molecular markers, mapping populations Traditionally, producer traits such as yield and disease resistance have been the primary breeding targets in many crops. In current agriculture, however, consumer-driven quality traits, such as flavour colour and nutritional value have become increasingly important and the same holds for the production of specific plant compounds which can be used as sources for bio-based applications. Breeding for Quality is directed at improving whole fruit/vegetable characteristics and plant compounds, where flavour, colour, texture, absence of antinutritional factors or allergens, and shelf-life are important breeding objectives. Breeding for Quality also comprises the efficient production of all kinds of compounds, which are used as ingredients by the food, pharmaceutical, chemical, textile, paper, etc. industries. Examples of such compounds are: carbohydrates (starch, fructans, cellulose), proteins (wheat gluten, pea storage proteins), vegetable fats/oils (rape seed oil, cocoa fat), and secondary metabolites like flavours, fragrances, and phytoestrogenic molecules. In breeding programs, the existing genetic variation is exploited to increase the yield of (or enrich mixtures in) the target compounds. For this, it is necessary to understand the metabolic routes leading to the synthesis of the desired compound, and to have knowledge on how these compounds can be determined in the plant material - explain the major characteristics of various quality traits; - define appropriate selection strategies for specific target traits; - apply relevant analytic and statistical screening techniques for trait evaluation; - use this knowledge to develop breeding strategies for improved resistance, tolerance and quality Activities: Study knowledge clips with theoretical assignments, group activities, individual assignments and literature Literature: Available through the course website 11
PBR32302 Breeding for Abiotic Stress Tolerance (Distance Learning) Teaching methods: 0.3 DKC; 1.7 DEL Contact person: Gerard van der Linden Lecturer(s): Gerard van der Linden Examiner(s): Gerard van der Linden Abiotic stress is the stress imposed on plants by the non-living environment. Abiotic stress is responsible for huge yield losses in crops around the world. In this course we will assess the impact that abiotic stresses (drought, salinity, nutrient deficiency) have on agricultural production, and provide you with knowledge and tools for successful breeding for abiotic stress tolerance. The following questions will be addressed: - What can agriculture do to minimize yield losses now and in a future where the climate changes, and input will be further restricted? - What are the requirements for successful breeding for abiotic stress tolerance? - How does a plant respond to abiotic stress, and which physiological and molecular mechanisms are important? - Which traits contribute to stress tolerance, how can these be measured and used for selection? How do modern genomics techniques contribute to abiotic stress tolerance breeding? After successful completion of this course students are expected to: - have acquired knowledge on how agriculture, crops and individual plants are affected by abiotic stress - have learned about main mechanisms that help plants to cope with abiotic stress - know about tools that can be used to monitor and understand the response and tolerance of plants to different abiotic stresses - be able to integrate the above knowledge for the design of a sensible breeding strategy for the improvement of abiotic stress tolerance in target crops.
