FOR 948 P9: The role of leaf senescence in relation to nitrogen uptake and translocation to the reproductive plant organs for genotypic differences in nitrogen efficiency of rapeseed (Project)

Decreasing the high nitrogen (N) balance surpluses in winter oilseed-rape production requires the breeding and cultivation of N-efficient cultivars. The overall objective of the project is the clarification of the role of leaf senescence and N mobilization from leaves in grain yield formation of rapeseed genotypes at limited N supply (N efficiency). The project thus represents the bridge between...

Collaborative project: Identification of quantitative resistance for production of new cultivars with durable broad-spectrum resistance against Phoma lingam causing stem canker of rapeseed - subproject 8 (Project)

Leptosphaeria maculans (anamorph Phoma lingam) causes stem cancer of oilseed rape, the most important fungal disease of oilseed rape in Germany. In current rapeseed varieties qualitative monogenic race-specific resistance genes have been overcome by the evolution of the pathogen. This represents a new challenge to the genetic improvement of durable fungal resistance in modern cultivars. Thus,...

Collaborative project: Evaluation of anthracnose resistant breeding lines from white lupine aiming at the development of varieties with particular emphasis on agronomical features and technological processing processing performences – Subproject 1 (Project)

Evaluation of breeding material of white lupin (Lupinus albus L.) with improved resistance to anthracnose aiming at the development of new varieties with special focus on agronomic traits and technological processing properties The aim of this study was to develop new varieties of white lupin with improved resistance to anthracnose. In three years, 20 breeding lines were evaluated on up to six...

Collaborative project: Development of a highly sensitive molecular method for diagnosis of Rubus stunt phytoplasma in rasberries, considering aspects of vector biology, modes of transmission and management strategies - subproject 1 (Project)

Rubus stunt is a bacterial plant disease that is caused in raspberries and other Rubus species by so called phytoplasmas, and can lead to significant yield losses. For a successful control of Rubus stunt, early identification of infected and often symptomless plants is of utmost importance. Thus, for detecting phytoplasmas a fast and highly sensitive molecular method (a Multiplex TaqMan qPCR...

FOR 536 P1: Amount, composition, and turnover of organic matter pools in grassland soils under typical steppe vegetation types of the Xilin River Basin (Inner Mongolia) with different grazing management (Project)

Heavy grazing in Leymus chinensis-dominated semi-arid grasslands results in changes in the amount, composition, and turnover of soil organic matter (SOM), due to the degradation of soil aggregation and release of aggregate-protected SOM, associated with enhanced susceptibility to soil erosion. This becomes evident as reduced bulk soil OC content, but especially as reduced microaggregation and...
