Collaborative project: Adaptation of agriculture to a changing climate: Analyses of the reaction of different barley genotypes to future CO2-concentrations in order to optimize the so-called CO2 fertilizer effect – subproject 3
Project
Project code: 2814504010
Contract period: 01.12.2010
- 30.07.2014
Budget: 35,300 Euro
Purpose of research: Experimental development
The project aims at getting information on genotypic differences in barley with respect to the reaction to the rising CO2 level in the atmosphere and to identify genomic regions involved in these different reactions by association genetics as a basis for a marker based selection procedure. To achieve this, 192 barley genotypes will be analysed on a 9k chip (iSelect) and based on these results on genetic diversity 100 genotypes will be selected for phenotyping. These genotypes will be grown in so called 'open top chambers' in a reguglar atmosphere and in a CO2 enriched atmosphere (600ppm). Yield, yield components and quality related traits will be estimated. Based on these phenotypic data and respective genotypic data - in addition taking into account variation in CO2 responsive genes detected in rice - association mapping will be conducted in order to identify genomic regions involved in a better adaptation to an enriched CO2 content. Respective markers will facilitate efficient marker based selection procedures in applied barley breeding thereby contributing to a better adaptation of barley to the climate change.
