The expected move towards more sustainable crop-livestock systems implies wider cultivation of perennial forage legumes. Alfalfa (Medicago sativa subsp. sativa) is the main legume in most temperate regions, especially where farm rely largely on conservation. White clover (Trifolium repens) and red pratense) are dominant specific regions systems. Although breeding progress for disease insect resistance has been achieved, these crops have shown lower rates genetic gain yield than major grain...
Alfalfa (Medicago sativa) is a major forage crop. The genetic progress slow in this legume species because of its autotetraploidy and allogamy. structure makes the construction maps difficult. To reach objective, to be able detect QTLs segregating populations, we used available codominant microsatellite markers (SSRs), most them identified model Medicago truncatula from EST database. A map was constructed with AFLP SSR using specific mapping procedures for autotetraploids. tetrasomic...
Alfalfa ( Medicago sativa L.) cultivars are synthetic populations formed from 8 to 200 parents and thus have a broad genetic base. Within‐cultivar variation was compared with among‐cultivar for energy value traits, morphological dry matter yield. Eleven cultivars, each represented by 15 clones of 7 20 genotypes, were evaluated in field plots simulating dense canopy at INRA (National Institute Agronomic Research), Lusignan France. Six harvests spanning 3 yr analyzed. Neutral detergent fiber...
In France, INRAE (Institut national de recherche pour l'agriculture, l'alimentation et l'environnement - French National Research Institute for Agriculture, Food and Environment) maintains a genebank of grass legume perennial species forage turf usages in the research unit P3F located Lusignan (region Nouvelle-Aquitaine). This is component plant pillar (BRC4Plants) Infrastructure RARe. Collections comprise natural populations collected across France other countries, landraces, cultivars...
Verticillium wilt is a major threat to alfalfa (Medicago sativa) and many other crops. The model legume Medicago truncatula was used as host for studying resistance susceptibility albo-atrum. In addition presenting well-established genetic resources, this wild plant species enables investigate biodiversity of the response pathogen putative crosstalk between disease symbiosis. Symptom scoring after root inoculation modelling curves allowed assessing levels in recombinant lines three crosses...
The seed is the carrier of genetic improvements brought about by modern plant breeding, and production carried out in accordance with certification systems to guarantee consistent high quality. In forage legumes, breeding efforts are primarily related vegetative development plant, although commercial success an agronomically superior cultivar dependent on a reliable supply competitively priced seed. three most important alfalfa (Medicago sativa L.), white clover (Trifolium repens red...
Wider and more profitable legume crop cultivation is an indispensable step for the agroecological transition of global agri-food systems but represents a challenge especially in Europe. Plant breeding pivotal this context. Research areas key interest are represented by innovative phenotypic genome-based selection procedures yield, tolerance to abiotic biotic stresses enhanced changing climate, intercropping, emerging quality traits. We see outmost priority exploration genomic (GS)...
Lucerne ( Medicago sativa ), a major perennial pasture legume, belongs to species complex that includes several subspecies with wild and cultivated populations. Stand establishment may be compromised by poor germination. Seed scarification, deterioration temperature have an impact on The objective of this study was analyse the genetic diversity lucerne germination in response three factors: (1) temperature, seven constant temperatures ranging from 5 40°C, tested 38 accessions, (2) seed...
Seed yield of alfalfa (Medicago sativa L.) is important in determining the effective distribution new cultivars to farmers. Many genetic and environmental factors affect seed yield. This study was conducted explain variation induced by either conditions or cultivars. We analyzed yield, aboveground phytomass, harvest index, components for a set 12 at four locations across France each three years. Each location x year combination considered an environment. weight, number pods per...
Abstract We report on the characterization and mapping of 76 simple sequence repeat (SSR) markers for Lolium perenne . These are publicly available or obtained either from genomic libraries enriched SSR motifs L. expressed tag (EST) clones. Four populations were used to map markers. A consensus linkage four containing 65 is presented, together with primer information a quality score indicating usefulness marker in different populations. The identified all seven groups.
Abstract Background Association studies are of great interest to identify genes explaining trait variation since they deal with more than just a few alleles like classical QTL analyses. They usually performed using collections representing wide range variability but which could present genetic substructure. The aim this paper is demonstrate that association can be synthetic varieties obtained after several panmictic generations. This demonstration based on an example between the gibberellic...
Functional-structural plant models are increasingly being used to analyse relationships between functioning and the topological spatial organisation of their modular structure. In this study, performance an individual-based model accounting for architecture population dynamics forage legumes in multi-species grasslands was assessed. Morphogenetic shoot root parameters were calibrated seven widely species. Other concerning C N metabolism obtained from literature. The evaluated using a series...
China's and Europe's dependence on imported protein is a threat to the food self-sufficiency of these regions. It could be solved by growing more legumes, including alfalfa that highest producer under temperate climate. To create productive high-value varieties, use large genetic diversity combined with genomic evaluation improve current breeding programs. study diversity, we have used set 395 accessions (i.e. populations), mainly from Europe, North South America China, fall dormancy ranging...
