|W+||3 credits||3G||A. Hund, B. Boller, C. Grieder, R. Kölliker, B. Studer|
|Abstract||Successful plant breeding requires knowledge of genetics, the methods to detect genetic variation and to utilize it for selection. The course builds on the course "Pflanzengenetik" and illustrates these basics by means of exercises and practical examples. This will be complemented by lessons in molecular breeding and latest developments in genotyping and phenotyping.|
|Objective||At the end of the course you will be able to design, assess and analyze variety test experiments. You will have basic knowledge on phenotyping and genotyping technologies, and know how to connect this information for quantitative trait loci (QTL) mapping and association analysis. Furthermore, you will be able to assess relationships among genotypes by means of multivariate statistics (e.g. cluster analysis) using genetic and phenotypic information.|
|Content||The course is organized in the following three modules:|
Module 1: Phenotyping of plant breeding experiments in the field phenotyping platform (FIP) at Eschikon Field Station.
Module 2: Statistical evaluation of the assessed data in R
Module 3: Molecular breeding
The course will be held at Eschikon Field Station, where 12 computers will be available for exercises with R.
We will observe the development of crops planted in the unique filed phenotyping platform. The field part includes two full days (July 02/03) during the summer semester break. The dates are chosen to allow you assessing buckwheat and wheat plants at stages of development, when meaningful measurements can be taken. In case somebody can't attend the course at these two days for justified reasons, we will seek for an alternative exercise.
During the course, we will have a closer look at wheat and buckwheat.
In wheat, we aim to teach the basic skills of phenotyping of plant development. You will assess the development using the simple scoring method, to train your breeder's eyes. Furtheremore, you will use sensors and indices used in the novel Field Phenotyping Platform (FIP), such as normalized difference vegetation index (NDVI), thermography and multispectral sensing. At the end of the course you will be able to judge the advantages of the "NDV-eye" vs. your Breeder's eye.
With Buckwheat we aim to establish a breeding program at ETH which is mainly operated by students. Here we need your enthusiasm, experience and input in order to succeed. You will score different traits of agronomic importance during the field day in summer. At the end of the course you should be able to pick the best varieties to make crosses for a planned breeding program organized by you and your fellow students of subsequent semesters.
In the statistical part of the course (module 2), you will learn how to process your data using the statistic package R and ASREML-R. For example, you will use the data assessed in module 1 to calculate heritabilities by means of analysis of variance. This part requires a basic understanding of R as taught in "Experimental Design and Applied Statistics in Agroecosystem Science" as well as of quantitative genetics as taught in "Pflanzengenetik". However these courses are not mandatory to enroll in plant breeding.
In the third module, you will learn about the genetic toolbox that is available for molecular breeding. Starting with the latest developments in DNA marker and genotyping technologies, the basic principles of genetic linkage mapping and QTL analysis will be illustrated. Novel breeding concepts such as genomic selection or breeding by design will be explained, discussed and evaluated for their potential to accelerate breeding progress in different crop species.
|Prerequisites / Notice||You need a Basic understanding of R as taught in "Experimental Design and Applied Statistics in Agroecosystem Science" as well as quantitative genetics as taught in "Pflanzengenetik". However these courses are not mandatory to enroll in plant breeding.|
|751-4106-00L||Crop Phenotyping||W||4 credits||4G||A. Walter, A. Hund, J. Leipner, F. Liebisch|
|Abstract||Phenotyping is mostly understood as a non-invasive, quantitative assessment of plant and organ morphology at different wavelengths. In this course, standard and customized phenotyping platforms and approaches are introduced and applied to characterize crop performance in the field and in the lab. The relevance of phenotyping for breeding, field management and precision agriculture is shown.|
|Objective||At the end of the course you will know a range of different phenotyping methods and how to assess their utility for different issues. You also know the critical stages of individual crops and you can identify promising traits and phenotyping approaches that are appropriate to improve a crop or its management in the field.|
|Content||Basic knowledge in physiology, breeding and management of our major crops will be combined with concepts of inheritance, experimental design, crop modelling and abiotic stress. By lectures, discussions, and hands-on experiments, you will learn to use image-based phenotyping methods for a performance assessment of genotypes of a breeding population and to assess the efficiency of measures of field management.|
Crops are exposed to different abiotic stress factors during their development. Adaptation of crops to extreme environmental conditions likely to be encountered in the course of the year (e.g. cold and heat stress; water-saturated or dry soils) has been achieved by plant breeding to a good extent. In many cases, however, there is enormous potential for optimization.
The most important mechanisms of plant adjustment towards stress will be explained, as well as critical stages identified in which stress affects yield most severely. You will learn methods by which the response of plants to environmental parameters is quantified non-destructively. You learn how to deal with the challenge of spatial variability in the field, when it is necessary to analyze a lot of genotypes. You will get to know different phenotyping methods in the field and under controlled conditions. An important parameter of analysis will be the measurement of the growth of roots and shoots and the response of this parameter to environmental stress. Moreover, you will apply thermography and multispectral image analysis as exemplary remote sensing methods and you will use these methods to calculate parameters such as canopy cover, water status and leaf greenness of individual plants or crop stands. Also, you will learn the use of chlorophyll fluorescence to assess the efficiency of the photosynthetic apparatus.

|751-3404-00L||Nutrient Fluxes in Soil-Plant Systems||W+||4 credits||4G||A. Oberson Dräyer, E. K. Bünemann König|
|Abstract||The course teaches knowledge and experimental techniques to study pools and processes underlying nutrient fluxes in soil-plant systems. Methods will be learned i) to analyze elements dynamics, ii) to determine the use efficiency by crops of nutrients added with fertilizers, iii) to study the fate of fertilizer nutrients not taken up by the crop and iv) to estimate symbiotic N2 fixation by legumes.|
|Objective||Using the element nitrogen (N) as model case, the student gets familiarized with techniques to assess the dynamics and availability of nutrients in the soil-plant system and to determine the use efficiency by crops of nutrients added with fertilizers. He/she learns about the use of stable isotope techniques for analyzing nutrient fluxes in soil-plant systems, and about the use of biochemical methods to obtain indicators on such fluxes. He/she is able to evaluate critically the tools used in agricultural or environmental studies dealing with fluxes of elements in soil-plant systems and the interpretation made of the results. Knowledge about processes and pools underlying nutrient cycles in agro-ecosystems will be improved.|
The student learns to work in the laboratory within a small team, to organize work in sub-groups, to exchange results obtained by these sub-groups, to look for information outside of the course (e.g. in the library, in the internet), to read and analyze this information critically, to synthesize both, the information from the literature and from the groups, and to present it in a written report and in an oral presentation.
|Content||This course teaches knowledge and methods to analyze the dynamics of elements in soil-plant systems and to determine the use efficiency by crops of nutrients added with mineral and organic fertilizers. It provides knowledge about various techniques (isotopic, chemical, biochemical) that can be used to evaluate |
i) content of elements in fertilizers, soils and plants;
ii) availability of elements in soils and fertilizers for plants;
iii) transfer of elements from a fertilizer to a crop;
iv) symbiotic N2 fixation by legumes.
Nitrogen will be used as model case.
The course will start with the discussion of analytical results on elemental contents in an organic fertilizer (e.g. animal manure, plant material) that has previously been labeled with the isotope 15N. To test the N efficiency of this fertilizer, a pot experiment (glasshouse study) will be designed. It will include soils with different characteristics, two test plants and fertilization treatments including the 15N labeled organic fertilizer and appropriate reference treatments.
Soils will be characterized for basic chemical properties and for biochemical characteristics that are related to the N dynamics. Plants will be harvested and analyzed for their dry matter production, their N isotope composition and for elemental contents. From the direct (15N) labeling approach, the proportion of N in the plant derived from the added fertilizers and the percentage of added fertilizer recovered in plant material will be calculated. The 15N analyses in the soil and in the plant material after the crop cycle will allow drawing a balance of the added fertilizer and discussing N losses. The comparison of 15N excess in legume and non-legume test plants will demonstrate the use of the enriched dilution method to estimate symbiotic N2 fixation by the legume.
The experiments are discussed and carried out by the students supervised by group members (two senior scientists, PhDs, laboratory staff). The students carry out the data analysis and report their findings in a written report and in an oral presentation.
