Wheat breeding and research
at the
State Plant Breeding Institute
in Hohenheim
LSA-UHOH 2
Breeding
• Development of new
varieties for farmers &
millers
• Identify new production
alternatives, e.g. Einkorn
• Aims: higher yield, better
quality, adaptation
Two main research areas
Research
• Examine genetic
architecture of single
traits in all wheat species
• Hybrid wheat
• Prebreeding for yield
• Optimized breeding
methods with GS
Selection
LSA-UHOH 3
• 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
Staff and facilities
LSA-UHOH 4
– For
• Durum (100 crosses/year)
• Emmer (20 crosses/year)
• Spelt (40 crosses/year)
• Einkorn (10 crosses/year)
– Aim: Establish as a crop itself
Elite breeding programs
Each September: offer to every
interested breeder to get exclusive
rights of new lines selected in 2 year
field trials
LSA-UHOH 5 5
• 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
Main topics for breeding programs
LSA-UHOH 6
Trial technique – 15.000 plots/year
LSA-UHOH 7
Quality lab – 5.000 samples/year
• Protein content
• SDSS
• Falling number
• B-value
• Gluten index
• TKM
LSA-UHOH 8 8
Specific research projects • Hybrid wheat
o Identify heterotic groups
o Improve pollination capability for seed production
o Elaborate best breeding schemes with markers
• Durum wheat
o Elaborate heritabilities and trait associations among agronomic and quality traits in spring and winter durum
o Perform QTL analyses for these traits
• Pre-breeding for grain yield in bread wheat
o Elaborate new methods and concepts to identify promising exotic lines
o Generate new variability via introgression of best exotic lines in elite material
o Generate new variability versus interspecifique crosses and increased recombination
