Vers des pois d'hiver plus performants

2020

International audience; Le développement des légumineuses dans la sole française, facteur dedurabilité, doit faire face à des contraintes de production qui peuventpénaliser leur rentabilité. Des avancées significatives, obtenues en poisd’hiver, devraient accélérer le progrès génétique et favoriser cette culture.

Sélection pour l'architecture racinaire et les interactions symbiotiques chez le pois

2019

National audience; La culture des légumineuses, et en particulier du pois, présente le double intérêt de permettre une production de graines à haute valeur nutritionnelle sans nécessité d’un apport d’engrais azoté et ainsi d’assurer à la fois sécurité alimentaire et respect de l’environnement. La nutrition azotée des légumineuses dépend en effet majoritairement de la fixation symbiotique de l’azote atmosphérique réalisée par des bactéries du sol, les rhizobia, au sein des nodosités, et dans une moindre mesure, de l’assimilation de l’azote minéral du sol par les racines. Cependant, la nutrition azotée du pois peut être insuffisante dans certains environnements et limiter ainsi le rendement d…

Pea MUlti-STress adaptation and biological regulations for yield improvement and stability

2019

National audience; Protein crops including pea are of high environmental and nutritional interest within the current context of climate change and reduction of inputs. However, pea yield irregularity due to multiple biotic and abiotic stresses limits its development in European cropping systems. Targetting muti-stress resistance and seed yield stability, PeaMUST (Pea MUlti-STress adaptation and biological regulations for yield improvement and stability) is an 8-year large French national project (2012- 2020) aiming at improving pea varieties to boost their introduction in cropping systems. Benefitting from an exceptional partnership of 28 public and private organisations and a wide range of…

GRaSP project Genetics of Rhizobia Selection by Pea

2019

Prod 2019-88aa; National audience; Because of their ability to fix nitrogen in symbiosis with soil bacteria, legumes such as peas have an important role to play in the development of a sustainable agriculture. However, in the field, biological nitrogen fixation (BNF) could be suboptimal as natural Rhizobium leguminosarum viciae (Rlv) populations are quantitatively and qualitatively heterogeneous, with strains varying in their competitiveness and efficiency of BNF [1,2]. There is a general agreement concerning the interest of Rlv inoculation for improving BNF and thus pea yield [3]. However, even when pea seeds are inoculated by efficient Rlv strains these can be outcompeted by indigenous rh…

Recherche des meilleurs couples pois-rhizobia. Premiers résultats et perspective

2019

Prod 2019-83g BAP GEAPSI INRA; National audience; La culture de légumineuses, et en particulier du pois, présente le double intérêt de permettre une production de graines à haute valeur nutritionnelle sans nécessité d’un apport d’engrais azoté. Cependant, la nutrition azotée du pois, et en particulier la fixation symbiotique de l’azote atmosphérique, peut être insuffisante dans certains environnements et limiter ainsi le rendement de la culture. L’établissement de la symbiose entre pois et rhizobium nécessite une reconnaissance mutuelle spécifique entre les deux partenaires, et une coordination de l'expression de nombreux gènes, indispensable à la mise en place des importantes modifications…

Assessment of infield spatial variability of available water content on an experimental platform.

2019

National audience; Innovative strategies and genetic engineering solutions are needed in order to manage agroecosystems more efficiently, build improved varieties and reduce inputs. In this context, phenotyping has recently become a bottleneck for the selection of high-achieving stresstolerant genotypes. In France, the Phenome project is responding to these stakes with a network of various high throughput facilities distributed in relevant geographical locations for studies at different scales and conditions. Phenovia is a platform managed by Terres Inovia. It is incorporated into the INRA experimental unit (EU) of Epoisses, located in Bretenière (Côte-d’Or, Bourgogne-Franche- Comté, France…

PeaMUST (2012-2019) – Pea Multi-Stress adaptation and biological regulations for yield improvement and stability

2017

BAP GEAPSI INRA; International audience; PeaMUST (2012-2019) is a large French national project whose objective is to develop novel pea varieties and optimize plant-symbiotic interactions for stabilized seed yield and quality, in the context of climate change and pesticide reduction. With the involvement of 28 partners from the public and private sectors, it will take advantage of NGS sequencing, genotyping and phenotyping technologies, to tackle the challenge of multiple stresses that penalize the performance of the pea crop.
