Agronomic performance of two generations (F12 and F13) of thirteen winter wheat composite cross wheat populations with differing cultivation histories in 2014/15. Organic Eprints
Weedon, Odette; Brumlop, Sarah; Heinrich, Sven; Boening, Andreas; Elsner, Maren; Finckh, Maria R.; Lammerts van Bueren, E.T.; Nuijten, E.; Messmer, Monika; Baresel, Jörg Peter; Goldringer, I.; Péter, Mikó; Megyeri, Maria; Borgen, Anders; Rasmussen, Søren K.; Pearce, Bruce; Wolfe, Martin.
As environmental and agronomic conditions are heterogeneous between and within locations, diversity within varieties or crop populations should increase adaptability to the changing and variable range of growing environments. The additional pressure of plant genetic diversity loss, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity and ensuring a “wider adaptation” capacity for crop varieties (Döring et al., 2011). A winter wheat (Triticum aestivum L.) CCP was created by intercrossing 20 varieties in 2001, through collaboration with the Elm Farm Research Centre and the John Innes Institute. In 2005, a seed batch of the F4 was equally...

Developments in breeding cereals for organic agriculture Inra
Wolfe, M.S.; Baresel, J.P.; Desclaux, D.; Goldringer, I.; Hoad, S.; Kovacs, G.; Loschenberger, F.; Miedaner, T.; Østergard, H.; Lammerts van Bueren, E.T..
The need for increased sustainability of performance in cereal varieties, particularly in organic agriculture (OA), is limited by the lack of varieties adapted to organic conditions. Here, the needs for breeding are reviewed in the context of three major marketing types, global, regional, local, in European OA. Currently, the effort is determined, partly, by the outcomes from trials that compare varieties under OA and CA (conventional agriculture) conditions. The differences are sufficiently large and important to warrant an increase in appropriate breeding. The wide range of environments within OA and between years, underlines the need to try to select for specific adaptation in target environments. The difficulty of doing so can be helped by...

Divergent evolution of wheat populations conducted under recurrent selection and dynamic management Inra
Goldringer, I.; Paillard, S.; Enjalbert, J.; David, J.; Brabant, P..
Les effets de la sélection sont étudiés sur une population composite de blé : sélection artificielle dans un programme de sélection récurrente (RS) et sélection naturelle dans un programme de gestion dynamique (DM). La population initiale, des populations de différents cycles de RS, et des populations maintenues huit années dans quatre environnements en DM, sont comparées pour des caractères agro-mrophologiques. Il est montré que RS et DM conduisent à des évolutions divergentes des populations. Peu de caractères (hauteur des plantes, précocité, fréquence de plantes barbues, sensibilité à l’oïdium et à la rouille brune) suffisent à différencier les populations issues des deux systèmes. Sauf pour la hauteur, la variabilité génétique a été conservée en GD,...

Innover autrement ? La recherche face à l’avènement d’un nouveau régime de production et de régulation des savoirs en génétique végétale Inra
Bonneuil, C.; Demeulenaere, E.; Thomas, F.; Joly, P.B.; Allaire, G.; Goldringer, I..
Reprenant les analyses d’économistes régulationnistes, Gilles Allaire s’est proposé, il y a quelques années, de montrer comment agriculture et agro-alimentaire sont passées d’un modèle “fordiste” de production à un modèle “post-fordiste”. Cette transition substitue au productivisme agricole des Trente Glorieuses, basé sur la standardisation du travail des producteurs et des produits, une économie de la qualité, modèle productif centré au contraire sur la différenciation des produits et la valorisation des qualités (Allaire, 1995, 2002). Nous analyserons ici dans une perspective similaire les transformations du secteur des semences et variétés végétales, lui aussi touché par une « crise des qualités génériques gérées centralement par les secteurs »...

Selection recurrente chez les autogames pour l'amelioration des varietes lignees pures : une revue bibliographique Inra
Kervella, J.; Goldringer, I.; Brabant, P..
Les améliorateurs de plantes autogames pratiquent une forme de sélection récurrente. Mais ce sont des croisements simples entre lignées pures précédemment sélectionnées qui sont la base d’un nouveau cycle de sélection et de croisements. La durée du cycle, les nombreuses générations d’autofécondations avant l’intercroisement et l’étroitesse de la base génétique de départ risquent d’être des facteurs limitants du progrès génétique à long terme. Pour éviter ces inconvénients, de nombreux expérimentateurs ont appliqué à des espèces autogames des schémas de sélection récurrente plus proches de ceux utilisés dans l’amélioration des allogames. Afin d’évaluer l’intérêt de tels schémas pour l’amélioration de la valeur en lignée des autogames, nous avons...

Selection recurrente chez les autogames pour l'amelioration des varietes lignees pures : une revue bibliographique.II Inra
Goldringer, I.; Brabant, P..
Des schémas de sélection récurrente, proches de ceux utilisés dans l’amélioration des espèces allogames, ont maintenant été appliqués à de nombreuses espèces autogames. Une revue bibliographique de ces expériences s’arrêtant aux articles parus en 1989 (Kervella et al, 1991) a permis d’en montrer la faisabilité ainsi que l’intérêt pour l’amélioration de la valeur en lignée. Cependant, de nombreux points restaient à optimiser : intercroisement, sélection précoce et prise en compte de l’aspect multicaractère. Nous présentons ici une revue complémentaire portant principalement sur les articles parus de 1990 à 1992, mais revenant également sur quelques articles plus anciens non cités dans la première revue. Une évolution dans l’approche, les méthodologies et...

Sensory Analyses and Nutritional Qualities of Hand-Made Breads with Organic Grown Wheat Bread Populations Organic Eprints
Vindras-Fouillet, Camille; Ranke, O.; Anglade, Jean-Pierre; Taupier-Létage, Bruno; Chable, Véronique; Goldringer, I..
Population varieties can meet the needs of organic farming as they are composed of diverse genotypes and have nutritional and sensory characteristics of interest. Their intra-specific genetic variability helps to adapt to the diversity of soil and climate conditions, management practices and needs. Moreover, an integrated organic bread sector has emerged willing to use more wheat populations. To explore sensory and nutritional potential of bread wheat populations, hedonic tests, sensory profile and nutritional analyses were implemented on eight wheat population varieties and one modern variety. Hedonic tests revealed consensus among consumer when ranking according to specific sensory characteristics and showed preferences for red wheat breads. Descriptive...

In Organic Agriculture, cultivation environments and agronomic practices are very diverse. This diversity can be handled with decentralized selection based on the knowledge of farmers and scientists. A collaborative work between associations from Réseau Semences Paysannes and the DEAP team from INRA du Moulon set up an innovative breeding approach on farm based on decentralization and participation of farmers. This approach makes it possible to (i) create new population varieties of bread wheat locally adapted (genetic innovation) (ii) set up an organizational scheme based on decentralization and co construction between actors (societal innovation) and (iii) develop experimental designs, create statistical and data management tools which stimulate these...

The relevance of outcrossing for the dynamic management of genetic resources in predominantly selfing Triticum aestivum L. (bread wheat) Inra
Enjalbert, J.; Goldringer, I.; David, J.; Brabant, P..
Le régime de reproduction est un paramètre essentiel pour le pilotage d’un programme de gestion dynamique des ressources génétiques. Cet article s’attache à l’estimation du taux d’allogamie dans six populations expérimentales de blé tendre, issues de deux pools génétiques différents (PA et PB) cultivés dans quatre sites distincts. Chaque population a subi dix années de multiplication en isolement, sans sélection consciente. Dans chacune d’elles, 78 individus ont été aléatoirement échantillonnés et génotypés pour vingt-cinq locus codominants, grâce à quinze sondes RFLP. Les taux d’allogamie ont été estimés à partir de l’hétérozygotie résiduelle multilocus. Un niveau d’allogamie élevé pour cette espèce cléistogame a été observé. Les estimations...

Time for a shift in crop production: embracing complexity through diversity at all levels Organic Eprints
Østergård, H.; Finckh, M.R.; Fontaine, L.; Goldringer, I.; Hoad, S.P.; Kristensen, K.; Lammerts van Bueren, E.T.; Mascher, F.; Munk, L.; Wolfe, M.S..
A radical shift in our approach to crop production is needed to ensure food security and to address the problems of soil degradation, loss of biodiversity, polluted and restricted water supplies, coupled with a future of fossil fuel limitations and increasingly variable climatic conditions. An interdisciplinary network of European scientists put forward visions for future crop production embracing the complexity of our socio-ecological system by applying the principle of diversity at all levels from soil micro-organisms to plant varieties and cropping systems. This approach, integrated with careful deployment of our finite global resources and implementation of appropriate sustainable technology, appears to be the only way to ensure the scale of system...
