Plant biotechnology joint project: 'Evaluation of wheat pre-breeding material respect of frost tolerance (FROWHEAT) - Project C

Project


Project code: JKI-RS-08-3367
Contract period: 01.09.2011 - 31.08.2014
Purpose of research: Applied research

Wheat is one of the most important crops for human nutrition. Frost tolerance is of prime importance for wheat yield in continental growing areas. Therefore, the project aims at estimating the genetic variability for frost tolerance present with winter wheat and at developing molecular markers for frost tolerance by applying a whole genome association mapping approach and a candidate gene approach. Based on these results markers will be developed facilitating efficient marker based selection procedures. Results obtained will lead to a deeper understanding of frost tolerance in wheat on the long term stabilizing winter wheat yield in continental growing areas. With an acreage of 217 Mio ha worldwide wheat is the most important crop species for food and feed. This holds also true for the EU27 and Germany where wheat was grown on 3.178 Mio ha with an average yield of 7.84 t/ha in 2009. High and stable wheat yields are of special importance for feeding the worlds growing population and to meet the demands for renewable resources. Besides drought, frost is an important abiotic factor limiting winter wheat yield especially in the eastern European and north american growing regions with a continental climate. Therefore, this project aims at improving the frost tolerance of wheat by applying a whole genome and a candidate gene association genetics approach for the development of markers facilitating an efficient marker based selection procedere for frost tolerance.
