How to manage the impact of gene flow on oilseed rape grain quality? Simulation case studies of three contrasted landscapes

2012

Abstract Grain admixture due to gene flow of oilseed rape (OSR) could be economically damaging. Different strategies are currently used or proposed to manage grain quality, ranging from homogenisation at the silo level to tactical decision rules at the field level. The relevance of these general strategies was appraised in the case of genetically modified (GM) OSR in three contrasted regions in Europe: Beauce Blesoise (France), Schleswig-Flensburg (Germany), and Fife (UK). Field patterns, crop allocation and agricultural practices were derived from existing datasets and complementary field surveys. Then a gene flow simulator was used to assess how the local contexts influenced the grain adm…

New approach to quantify in situ storage protein bodies in M. truncatula immature seeds

2013

Grain legumes play a worldwide role as a source of plant proteins for feed and food. During seed mid-maturation (16-20 DAP), a semi-quantitative analysis of vicilin (globulin7S) accumulation was assessed in the model legume M.truncatula. The populations of vicilincontaining protein bodies are distinguished by their number and size which allowed proposing a model of their biogenesis. Two distributions were detected, enabling a separation of their processing at early and mid maturation stages. The largest protein bodies corresponding to mature vicilin aggregations which have probably reached their final size were shown to be formed by the fusion of the small bodies. This approach using a comb…

Association of SNP markers with pea grain protein and grain yield traits in Italy : preliminary results

2013

Grain yield and quality are the main economically important traits in breeding of field pea (Pisum sativum L.). The objective of our work was investigating trait-marker associations in elite pea germplasm, with the final aim to develop marker-assisted selection procedures for these traits. The genetic base for this study was represented by three connected recombinant inbred line (RIL) populations obtained from paired crosses between three genotypes (the varieties Attika, Isard and Kaspa) which featured different geographical origin and outstanding adaptation to Italian cropping environments. At least 86 F7 lines per RIL generated by single-seed descent were evaluated for grain yield, plant …

Ex situ evaluation of grain yield in local landraces of faba bean (Vicia faba L.) from Serbia

2013

International audience; Faba bean (Vicia faba L.) originated in Central Asian centre of diversity. Faba bean is one of the most ancient cultivated plant species in the world, along with several other grain legumes, and cereals. Numerous archaeobotanical fi ndings, supported by rich linguistic evidence (1), witness its early and rapid distribution during Neolithic from Near East to Europe, North Africa and Central and East Asia and an important role it had in everyday diets of the ancestors of modern Old World nations. Today, faba bean is one of the most important annual legume crops for human consumption, animal feeding and for non-food purposes. Conservation and sustainable utilisation of …

Impact des techniques agricoles sur l’assemblage des communautés adventices

2012

National audience; Les pratiques agricoles jouent un rôle majeur dans le devenir des espèces adventices comme le montre les changements importants de composition et la perte de diversité des flores adventices depuis 1950. Malgré ce constat, les processus de filtrage des espèces par les différentes pratiques agricoles restent encore mal connu. Dans cette étude, nous avons cherché à mettre en évidence les liens entre les traits des adventices et leur réponse à des pratiques culturales. Dans un premier temps, une analyse RLQ a été conduite sur 218 parcelles de blé d’hiver issues du réseau Biovigilance Flore couvrant toute la France pour déterminer quels traits des adventices répondent aux diff…

Caractérisation d'une collection de variétés anciennes de blé pour leur aptitude à former les mycorhizes et impact sur la qualité des graines

2014

Le blé (genre Tritucum aestivum, famille des Poaceae) est une céréale d’intérêt agronomique très important. Certaines variétés très anciennes sont mise de côté pour des variétés plus récentes souvent sélectionnées pour répondre à une culture intensive consommatrice de produits phytosanitaires. L’agriculture biologique, système de production supposant une réduction des intrants chimiques de synthèse afin de préserver l’écosystème, peut se définir comme une pratique où l’emploi d’engrais synthétiques, de pesticides chimiques et d’organismes génétiquement modifiés est prohibé. Cette pratique gagne de plus en plus en popularité et la superficie des terres cultivées de cette manière a crû de 60 …
