1. Wheat breeding and research at the State Plant Breeding Institute
in Hohenheim

2. Two main research areas
Breeding
Development of new varieties for farmers & millers
Identify new production alternatives, e.g. Einkorn
Aims: higher yield, better quality, adaptation
Research
Examine genetic architecture of single traits in all wheat species
Hybrid wheat
Prebreeding for yield
Optimized breeding methods with GS
Selection 2

3. Staff and facilities 1 scientist – Dr. F. Longin 7 technicians
PhD, PostDoc, Students…
~ 8 ha of nurseries
> 20 different field locations
Special nurseries for stress - FHB, virus, frost
Quality lab for b- value, sds, falling, GI, protein content, vitreousness and dark points
Machinery for threshing and dehulling 3

4. Elite breeding programs
For
Durum (100 crosses/year)
Emmer (20 crosses/year)
Spelt (40 crosses/year)
Einkorn (10 crosses/year)
Aim: Establish as a crop itself
Each September: offer to every interested breeder to get exclusive rights of new lines selected in 2 year field trials 4

5. Main topics for breeding programs
Durum:
Resistance against Fusarium and Virus
Winterhardiness
Quality
Spelt
Increase of grain yield and baking quality
Emmer
Reduce plant height and increase frost tolerance
Einkorn
Reduce plant height 5

6. Trial technique – 15.000 plots/year

7. Quality lab – 5.000 samples/year
Protein content
SDSS
Falling number
B-value
Gluten index
TKM

8. Specific research projects
Hybrid wheat
Identify heterotic groups
Improve pollination capability for seed production
Elaborate best breeding schemes with markers
Durum wheat
Elaborate heritabilities and trait associations among agronomic and quality traits in spring and winter durum
Perform QTL analyses for these traits
Pre-breeding for grain yield in bread wheat
Elaborate new methods and concepts to identify promising exotic lines
Generate new variability via introgression of best exotic lines in elite material
Generate new variability versus interspecifique crosses and increased recombination 8
