Key Note speaker Plant resistance and architecture for protection of pulses against biotic stresses

2019

Prod 2019-88l BAP GEAPSI INRA DOCT; National audience; Major diseases and pests, such as root rots, ascochyta blights and aphids, are limiting factors to cool season pulse production in many countries worldwide, especially in Europe. In the context of pesticide reduction, plant genetic resistance and architecture are main traits that can be mobilised in breeding for disease and pest management. Knowledge of quantitative resistance to major diseases and pests of pea and faba bean in France has benefited from the development of sequenced genomes and massive SNP markers [1], which have recently been highly valuable to identify candidate genes controlling resistance. Fine mapping and sequencing…

Complementary approaches towards the discovery of genes controlling yield in pea

2019

International audience; Pea is one of the most important grain legumes in the world. Improving pea yield is a critical breedingtarget in the current context of consumers’ increasing demand for plant proteins for food and feed. Becauseof its polygenic nature and the impact of the environment, breeding for higher yield is challenging. Weinvestigated the genetic determinism of yield (SW), seed number (SN) and thousand seed weight (TSW) usingboth linkage and linkage-disequilibrium approaches.Nine interconnected mapping populations, representing a total of 1,213 recombinant inbred lineswere phenotyped for SW, SN and TSW in six different field environments. These lines were genotyped usingthe Gen…

Intérêt d'aménagements paysagers pour la biodiversité : exemple d'ingénierie agroécologique sur le domaine expérimental d'Epoisses (Inra Dijon)

2013

The biodiversity conservation is one of the major agricultural issues of the XXIst century. The intensification of agriculture and the redesign of the agricultural landscape (grouping of fields, …) lead to huge decreases or damages of semi-naturals habitats, known to promote biodiversity at the farm and the landscape scale, and now recognised as “topographic surface equivalence” in France.In the experimental site of Epoisses (INRA of Dijon), a study to design the landscape elements in favour of the biodiversity has been initiated. Improving the management of existing habitats (woods, hedges, ditches, sown grass margin strips), establishing hedges, flower strips, redesigning the field organi…

Vers des variétés de légumineuses à graines mieux adaptées à l’alimentation humaine

2012

National audience; Les légumineuses font partie des aliments de l’homme depuis les premiers âges de l’agriculture et sont très présentes dans les repas des pays en développement. Outre un apport en réserves carbonées qui selon les espèces sont à dominante d’amidons ou de lipides, ces graines riches en protéines enrichissent les régimes en acides aminés très complémentaires de ceux des céréales. L’aptitude des racines de légumineuses à établir une symbiose avec des bactéries rhizobiacées qui leur permet d’utiliser l’azote de l’air comme principale ressource d’azote, combinée à une consommation directe par l’homme de ces graines qui permet de diminuer la consommation de viandes, constituent u…

Towards bruchid resistance in pulses

2019

Prod 2019-88ff BAP GEAPSI INRA; National audience; Seed weevils (Bruchus spp.) are major pests of pulses, causing yield losses and affecting marketability 1,2 . Available insecticides have low efficiency and important negative impacts on the environment, humans and non-target organisms. Therefore, breeding resistant varieties represent the most promising strategy to overcome seed weevils. The pyramiding of several resistance genes in cultivars is an important objective because this will make the resistance more durable and suitable for sustainable agriculture. The PeaMUST project (ANR-11-BTBR0002) aims at discovering the mechanisms of tolerance and resistance to bruchids in pea (Pisum sativ…

RésiLens: A research project aiming at identifying bruchid and root rot resistance sources in lentil (Lens culinaris)

2019

National audience; Introducing legumes in modern cropping systems increases crop diversity and reduces the use of external inputs. It thus contributes to achieving sustainable food and feed production. Lentil (Lens culinaris Medik.) is an environmentally friendly, nutritious, protein-rich legume food crop. It is grown in a wide range of climatic conditions and fixes atmospheric nitrogen through bacterial symbiosis. In France, lentil cultivated areas are continuously increasing but are still largely inferior to the areas cultivated with cereals or other legumes such as pea and faba bean. One of the most serious problems for lentil cultivation is due to the insect pests known as seed beetles …

Towards conservation of the local landraces of faba bean (Vicia faba) in Serbia.

2010

International audience; Today, faba bean (Vicia faba L.) in Serbia is almost an extinct crop, without official data on harvested area or production for decades. However, faba bean survived in certain parts of the country, especially along the rivers Southern and Great Morava, in the centre, and in Backa, in the north. In these parts, faba bean is cultivated mostly to suit one's own needs and sporadically is brought to green markets. It is grown as a garden crop, with sowing either in spring or during winter in order to achieve faster growth in comparison to the first schedule. First steps towards the conservation of faba bean local landraces in Serbia have been made within the multilateral …

2013

Low vicine and convicine content in faba bean seeds is under oligogenic control and can be easily monitored by breeding. Aim of the study was to show that new faba beans (FB) genotypes with low content of vicine and convicine (low V/C FB) produced by selection, are non-toxic and non-hemolytic even when ingested in large amounts by highly susceptible glucose-6-phosphate dehydrogenase (G6PD)-deficient individuals. Evidence indicates that V/C, amino-pyrimidine derivatives present in high amounts in normal FB, are the causative agents of favism, ie severe oxidative damage and hemolysis occurring in G6PD-deficient subjects after FB ingestion. In vitro, micromolar V/C elicits oxidative damage in …
