DIVERSIFOOD Final Congress - Session 3 - Poster presentations

  1. 1. Participatory on-farm breeding and management of wheat mixtures Gaëlle van Frank, Pierre Rivière, Sophie Pin, Pauline Lhôte, Alexandre Duclouet, Olivier David, Yannick de Oliveira, Hervé Aribaud, Julien Bailly, Raphaël Baltassat, Lea Bernard, André Bochede, François Caizergue, Christian Dalmasso, Louisette Daubignard, Matthias Fattet, Jean-Sébastien Gascuel, Robin Gasnier, Ida Guignard, Christan Hardillier, Alexandre Hyacinthe, Sophie Leroy, Hélène Montaz, Adrien Pelletier, Olivier Ranke, Renaud de Rousiers, Marc Vanoverschelde, David Voireuchon, Sophie Woehling, Isabelle Goldringer
  2. 2. Participatory on-farm breeding and management of wheat mixtures Objective Assess the impacts of different selection practices •  Select within components before mixing •  Select within the mixture Methods •  Co-construction of an on-farm experiment •  Test of 3 selection practices by a dozen farmers
  3. 3. Participatory on-farm breeding and management of wheat mixtures Main result •  Benefits of growing mixtures •  Contrasted advantages of different selection practices
  4. 4. Participatory on-farm breeding and management of wheat mixtures •  Farmers selected traits related to productivity •  Responses were positive for most traits •  Larger responses when selecting within mixtures, while conserving more diversity when selecting within components before mixing gaelle.van-frank@inra.fr Take Home Message
  5. 5. Revisiting Vicia faba breeding criteria to include functional floral traits María José Suso and Carmen Mateos Institute for Sustainable Agriculture (CSIC), Spain, www.ias.csic.es, ge1susom@uco.es
  6. 6. Revisiting Vicia faba breeding criteria to include functional floral traits Objective How can farmers integrate faba bean crop into their local farming systems so as to maximize synergies between food production and bee pollinator protection? Methods Breeding approaches Open-pollination Pollinator exclusion Cropping systems Monoculture Strip-intercropping DIA Floral traits affecting pollinator The manipulation of functional floral traits for the benefit of pollinators has been suggested in the bid to both enhance both food production and bee pollinator maintenance
  7. 7. Revisiting Vicia faba breeding criteria to include functional floral traits Open-pollination approach Pollinator exclusion approach Functional floral traits for improving yield determinants and resources for bees There were differences in functional floral trait associations with yield determinants across the breeding approaches seeds/pod seeds/pod seeds on the main stem seeds on the main stem seeds per plant seeds per plant seed size seed size Principal Components Analysis Results
  8. 8. Revisiting Vicia faba breeding criteria to include functional floral traits In summary, §  Differences in functional floral traits of gene-pools derived from different breeding approaches were quantified to work towards creating a “super-pollination” environment §  Overall the results revealed that interactive effects of functional floral traits and breeding strategy do affect yield determinants. §  We highlight the opportunity toward creating, in farmer fields, a synergy between food production and biodiversity (bee fauna) conservation. synergy
  9. 9. Comparison of two strategies to increase intra-varietal diversity Estelle Serpolay1, Anne-Lise Villard2 and Véronique Chable2
  10. 10. Comparison of two strategies to increase intra-varietal diversity https://www.hamiltonbeach.com/blenders Method Researchers: farmer’s question into experimentation (developed with him (and others) Differences of adaptation and evolution potential (natural and human) of different breeding strategies Objective https://wilsondeane.wordpress.com/ 2012/05/15/yellow-cup-blue-birds-cake/ ?
  11. 11. Comparison of two strategies to increase intra-varietal diversity Main result Environment has a stronger influence on the population evolution than the breeding strategy (wheat) From a simple question, the experimentation is complexifying a lot...
  12. 12. Comparison of two strategies to increase intra-varietal diversity Estelle.serpolay-besson@itab.asso.fr • Thank you to all the students that have worked on this experiment along the years Farmers’ questions to researchers are real research questions
  13. 13. Development and characterization of barley populations for sustainable agriculture Lorenzo Raggi1, Salvatore Ceccarelli2, Valeria Negri1 1 Università degli Studi di Perugia, Dipartimento di Scienze Agrarie, Alimentari e Ambientali, Italy 2 Rete Semi Rurali, Italy
  14. 14. Development and characterization of barley populations for sustainable agriculture Objective Test: (i) yield and yield stability of barley materials selected through Evolutionary Breeding (EB) under different agro- climatic and management conditions; (ii) effect of on-farm evolution on populations diversity. Methods Multi-environment trials in 3 sites located in Central Italy (2 low-input and 1 organic): total of 8 “year- location- management”. 281 SNP markers to investigate parental contribution and populations genetic diversity evolution.
  15. 15. Main result Populations show superior combination of both grain yield and stability in marginal conditions. Parental populations differentially contributed to initial population diversity; diversity rapidly evolved on-farm. Development and characterization of barley populations for sustainable agriculture
  16. 16. •  Characteristics of materials required for developing populations for sustainable agriculture. •  Utility & prospective of use of mol. mark. for population evolution analysis. •  Populations can rapidly evolve on-farm and be effectively cultivated under marginal conditions. lorenzo.raggi@unipg.it Take Home Message Development and characterization of barley populations for sustainable agriculture
  17. 17. Efficient methods to develop new sweet corn cultivars for organic systems Jared Zystro and William Tracy
  18. 18. Efficient methods to develop new sweet corn cultivars for organic systems Objective •  Test the use of improved experimental design and genomic information to rapidly identify potential new organically-adapted varieties. Methods •  40 sugary enhancer maize inbred lines and 100 hybrid progeny were evaluated in 11 environments. The parents were genotyped and classical and genomic tools were used to predict untested genotypes.
  19. 19. Efficient methods to develop new sweet corn cultivars for organic systems Main result •  Correlations between predicted values and actual values ranged from 0.36 and 0.82 for classical prediction and 0.38 0.93 for genomic prediction
  20. 20. Efficient methods to develop new sweet corn cultivars for organic systems •  Classical and genomic both offer good potential for selecting parents for new organic varieties and breeding populations. •  Based on the results, new open pollinated and hybrid varieties are being developed for testing and release •  Contact emails: wftracy@wisc.edu jared.zystro@wisc.edu •  Project funded by the USDA-NIFA Organic Research and Education Initiative Take Home Message
