A group of scientists won the 2017 Olam Prize for Innovation in Food Security for applying advanced breeding techniques to strains of primitive and modern wheat to develop a set of
durum wheat varieties that can not only withstand constant 35 to 40 degree Celsius (95 to 104 degree Fahrenheit) heat,
Joint author Agata Gadaleta from Università di Bari Aldo Moro, Italy, said: «Now that we've identified the cell wall characteristics that make a common wheat variety resistant to FHB, work can begin on transferring these traits to vulnerable
durum wheat varieties.
The researchers hope that the identification of these unique cell wall traits in FHB - resistant common wheat could help in breeding
durum wheat varieties that are able to defend themselves against infection, and reduce fungal toxin contamination in food.
The group decided to compare the ancient grains spelt, emmer, and einkorn with the more common bread and
durum wheat varieties.

Lead author Daniela Bellincampi from Sapienza Università di Roma, Italy, said: «Breeding disease - resistant
varieties of
durum wheat is probably the best economic and ecological strategy for fighting this invasive and destructive disease.
These insights could help to produce stronger, disease - resistant
varieties of
durum wheat for improved pasta production.
The researchers compared a disease - resistant
variety of common
wheat and a susceptible
variety of
durum wheat.
«As of 2012, the start of the most recent phase of ACIAR - funded work, Afghanistan partners have developed and released 12 high - yielding and disease resistant bread
wheat varieties, as well as 3
varieties of
durum wheat, 2 of barley and 3 of maize,» said Rajiv Sharma, a senior
wheat scientist at CIMMYT and country liaison officer for CIMMYT in Afghanistan.
The ultimate beneficiaries of the fruits of this network are farmers who will receive improved bread
wheat,
durum wheat and triticale
varieties.
If you believe in eating less complex grains, einkorn, barley, and rye are diploid, with two sets of chromosomes; emmer and
durum including kamut are a little more complex; they're tetraploids with four sets of chromosomes; spelt and bread
wheat varieties are hexaploid with six sets of chromosomes.
