Potato breeding for stress tolerance and processing quality for organic farming - LfL
Project
Project code: 2822OE062
Contract period: 01.03.2024
- 28.02.2029
Budget: 709,450 Euro
Purpose of research: Applied research
Keywords: abiotic stress, crop production, genetic resources, ingredients, potato, climate change adaptation, product quality, resistance, organic farming
Organic farming places special demands on potato varieties. Important are strong resistance to pests, (especially late blight) rapid juvenile development, weed suppression and high nutrient efficiency. As biotic and abiotic stress factors also change with climate change, it is crucial to keep yields and quality stable with adapted cultivation methods and through new, resistant varieties. However, these must also meet market requirements in terms of taste, appearance and good processing quality. The project presented here uses genetically diverse material to breed new potato varieties. Progeny are selected on organically certified plots and selection clones are tested over several years at different environments. Scientific research focusses on the physiology of drought and heat tolerance, the functional genetics of late blight resistance, and nutrient efficiency are investigated. The project team comprises university institutes, research facilities, breeding companies, organic farmers, organic associations and potato processors. This network combines scientific expertise with many years of experience in participatory potato breeding and enables the broad use of genetic resources. The following measures are to be implemented as part of the project: • Screening of gene bank accessions • use and further development of late blight resistant prebreeding material • goal-oriented choice of crossing parents • selection of progeny under organic conditions • field trials for late blight resistance and stress tolerance • analysis of tuber components, tuber quality, and suitability for processing • investigation of nutrient uptake and nutrient utilisation • elucidation of the genetic and physiological background to resistance, nutrient management and stress tolerance
