Context and Issues

Bread wheat Triticum aestivum L is the third most cultivated cereal in the world, after corn and rice. World production was estimated to 650 million tons in 2010. It is the most widely cultivated species in France, the largest producer in the EU: 36 million tons in 2008. The culture covers are about 5 million ha which gives an average yield of 72 q / ha.

Wheat yield has more than tripled over the last 45 years but has stagnated since 2000. This increase is explained by efficient cultural practices in intensive use of inputs and by improvement of varieties. Current issues of growing wheat, and thus its improvement, involve the implementation of an integrated approach. This will take into account the impacts of climate change, more simplified agricultural practices and the need to produce better and in sustainable manner, in accordance with the rules defined at the Grenelle of Environment (Ecophyto 2018).

Topics/Objectives

Study the structuration of the genetic diversity, organization of genomes and of species complexes

• Enlargement of the variability of bread wheat by interspecific hybrids between wheat and related species.
• study of structural and functional evolution of genomes A, B and D

Create innovative plant material and assess its impact in different contexts

• Co-supervising with colleagues from UMR Clermont-Ferrand and Estrées-Mons, of programs dedicated to the development of hardy, multi-resistant to diseases, of good baking quality and high yielding varieties.
• Assessment of the value of our varieties (Koreli, Barok, Folklor, Lyrik) in crop management with different input levels.
• Demonstration of the interest of these varieties in integrated management, through a significant decrease of inputs while maintaining economic margin / ha comparable to that obtained in reasoned intensive management.

Private partnership

For over 30 years, collaborations have been developed with breeding institutions mostly grouped in GIS or GIE as “GIE Club5”, “CETAC” and “GIE Triticale and durum Wheat”. We are also collaborating with technical institutes as Arvalis–Plant Institute and ITAB (Technical Institute of Organic Agriculture) as well as Chambers of Agriculture on more than twenty French departments.
