Fruit tree canker, caused by the fungus Neonectria ditissima, has become a threat for Swedish apple production. No efficient protective measures are available and no complete genetic resistance is known in apple. However, apple genotypes differ in the level of partial resistance which must be fully exploited. We aim to use recent advances in phenotyping for canker resistance to reveal genetic differences among rootstocks and clarify the impact of a rootstock on scion’s ability to resist the infection. Furthermore, we aim to enhance cultivars’ and rootstocks' genetic resistance with cultivation practices such as Ca fertilization. By that we will produce important knowledge and develop efficient tools for reducing canker damages in apple orchards, in Sweden and internationally. This knowledge will also be applicable for other tree species. The project will be performed by an international research team in collaboration with Äppelriket Österlen Ek. För.
Fruktträdskräfta som orsakas av svampen Neonectria ditissima är ett hot för svensk äppleproduktion. Det finns inga effektiva växtskyddsåtgärder mot sjukdomen och ingen fullständig resistens har hittats hos äpple. Det finns genetiska skillnader i partiell resistens mellan olika genotyper som ska utnyttjas fullt ut. Vi ämnar att använda de senaste framstegen inom fenotypning för kräftresistens för att påvisa de genetiska skillnaderna mellan olika grundstammar och klargöra effekterna av grundtam på den ympade sortens förmåga att motstå infektionen. Dessutom ämnar vi att förstärka sorternas och grundstammarnas genetiska resistens med odlingsmetoder som Ca gödsling. Därigenom kommer vi att producera viktig kunskap och utveckla effektiva verktyg för att minska kräftskador i äppleodlingar i Sverige och internationellt. Denna kunskap kommer också att vara användbar på andra växtslag. Projektet kommer att genomföras av ett internationellt forskarlag i samarbete med Äppelriket Österlen Ek.För.

For sustainable future development, it is essential to recirculate plant nutrients from different parts of society,
especially sewage plants, back to arable land. The aim of the proposed project is to ensure that high-quality fertiliser
products attractive for agricultural use are produced from …

In the proposed project, we will explore the benefits of increasing the longevity of dairy cows under Swedish conditions by changes in herd management. We will focus on effects on methane emissions by modelling, using existing data from the Swedish Official Milk Recording Scheme and results from an …

The sensory attributes of the raw milk are of major importance for the quality of the resulting dairy products. Since the early 90’ies, the so-called “blueberry off-flavour” has caused severe economic consequences for affected dairy farmers. The mechanism behind is still unclear, although forages …

Humus is an important indicator of soil quality and soil organic carbon (SOC) sequestration is a cost-effective measure to reduce the climatic impact of food production systems. The national soil-monitoring program (SMP) show an upward trend in SOC during the past 20 years, mostly attributed to an …

Conventional technology is virtually unable to measure complete GHG budgets of drained organic soils, which may provide misleading results. So, global estimates of GHG emissions are based on coarse assumptions that don’t take into account the complexity of agroecosystems. Better data are needed for …
