Development and field testing of a new breeding concept for stable lettuce production in organic farming
Project
Project code: 2819OE100
Contract period: 01.03.2020

Despite increasing demand, the cultivation of organically produced lettuce has stagnated in Germany. The reason is that lettuce cultivation in organic cropping is not stable. Diseases like downy mildew and abiotic stress factors often led to severe losses. Lettuce varieties with a combined high quality and stable yield are lacking on the market. New breeding methods were first tested in the projects 2810OE064 and 2810OE069. Results showed that planting line mixtures and cross populations are promising approaches to more stable yields. This can be explained with a higher degree of diversity compared to homozygous varieties which results in more variable reactions to deseases and stress factors. The aim of the project is to develop a sustainable concept for organic lettuce cropping based on these new breeding methods considering local growing conditions.
