Breeding of oilseed rape with reduced fibre content (LoFiRaps)
Project
Project code: 22036418
Contract period: 15.08.2019
- 14.08.2022
Budget: 211,438 Euro
Purpose of research: Applied research
The continuous increase of oil and protein content as well as of the protein quality is an ongoing breeding objective in oilseed rape. A noticeable further increase of oil and protein content in the seed is only possible through the reduction of fibre content. Fibre content is consisting of hemicellulose, cellulose and lignin. From a nutrition physiological point of view, the reduction of indigestible lignin is most important. A genetic reduction of lignin content by breeding would enhance market opportunities in the animal feeding sector and of the oilseed rape protein in the food sector. The overall aim of this project is the genetic analysis and utilization of available genetic variation for reduced fibre content in oilseed rape. Furthermore, breeding material with significantly reduced fibre content through genetic recombination of different resources will generate new quality improved germplasm. Laboratory reference methods accurately determining seed fibre fractions are used to improve already existing NIRS calibrations for hemicellulose, cellulose and lignin content. Quality characterized seed samples provided to breeding companies allow for validation and improvement of local NIRS calibrations. Genetically improving the quality of the oil-extracted meal enable the development of improved oilseed rape cultivars, which will enhance economic competitiveness of the oilseed rape crop and result in a benefit for the domestic agriculture. Expected project results are believed to intensify scientific and commercial breeding activities with respect to the development of qualitatively improved oilseed rape varieties with enhanced market opportunities in the feed and food industry.
