Healthy seeds are a prerequisite for sustainable food systems. The seed-borne plant disease, common bunt (CB) in wheat, caused by the fungi Tilletia tritici and T. laevis, is a major problem in agriculture. Efficient chemical seed treatments exist, but it is often difficult to keep up with autumn sowing and in organic agriculture, this is not an option. A sustainable and environmentally friendly alternative is to grow resistant or tolerant cultivars.
Over the last years, occurrence of common bunt in Sweden has increased significantly. In 2020, 42% of seeds intended for certification was infected with CB. For increased yields and food security, we must understand the contributing cause behind the increased CB problem in Sweden. Our goal is to identify the cause of the increase by studying 1) occurrence and distribution of Tilletia races in Sweden, 2) their genetic variation, and 3) resistance in wheat cultivars adapted for conventional and organic cultivation in Sweden.
Friskt utsäde är en förutsättning för hållbara livsmedelssystem. Den utsädesburna växtsjukdomen vanlig stinksot (VS) i vete, orsakat av svamparna Tilletia tritici och T. laevis är ett stort problem i jordbruket. Tillgång till effektiva betningsmedel finns, men då perioden mellan skörd och höstsådd är kort är det svårt att hinna med i höstvete. I ekologisk produktion är kemisk betning inget alternativ. Ett hållbart och miljövänligt alternativ är odling av resistenta eller toleranta sorter.
De senaste åren har sjukdomen ökat betydligt i Sverige. År 2020 förekom smitta av VS i 42 % av utsäde ämnat för certifiering. För en ökad skörd och livsmedelssäkerhet måste vi förstå den bidragande orsaken till den ökade VS-problematiken i Sverige. Vårt mål är att identifiera orsaken till ökningen genom att undersöka: 1) förekomst och spridning av Tilletia-raser i Sverige, 2) deras genetiska variation, och 3) resistens hos vetesorter anpassade för konventionell och ekologisk odling i Sverige.
