Coming International and national events EDITORIAL The Covid 19 crisis reminds us that the mankind is not always in a dominant position when interacting with nature. People aware of life sciences cannot really be surprised as this kind of event affects mankind since immemorial times. But in practice, at the scale of a human life, this situation is very exceptional: all countries are progressively affected, and even if the summer season may slow down the epidemic in the Northern hemisphere, the pandemic of Covid 19 might go on in the Southern part of the globe, and the time span to reach effective sanitary solutions have good chances to reach one year, since things might be very fluctuant as long as a vaccine is not developed and populations treated. Our Sunflower Conference being an international event which gathers the world community of sunflower, we had no other choice than postponing it by one year. Sometimes, Nature decides for us. It is a pity for all of us, but we are certain that our investment will not be lost, whether as a participant proposing a communication or organizer. Finally, it has never been so relevant to compare the sunflower conference to the Olympic Games…

The 20th International Sunflower Conference is postponed to June 2021 due to the Covid 19 pandemic
https://isc2020.com/ The message of the organizing team addressed to the participants gives practical information on the next steps: “Global crisis caused by COVID-19 virus is affecting all aspects of our lives. Institute of Field and Vegetable Crops, Novi Sad, and International Sunflower Association, as organizers of the 20th International Sunflower Conference in Novi Sad, are closely monitoring the situation since the beginning of the crisis. The health, safety and security of all conference participants, speakers, sponsors, exhibitors and others are, of course, more important than anything else. Since further development of the situation cannot be foreseen, we have decided to postpone the conference for the next year. The new time for the conference is June 21st to June 24th, 2021. The conference will be held in the same place, Master center, in Novi Sad, Serbia. Already paid registration fees and hotel reservations will remain valid, and any individual requests on this issue will be handled with the supporting agency Panacomp. We hope that the sponsors and exhibitors will agree to continue supporting the conference. Conference program and speakers will remain the same, maybe with minor changes. Already received abstracts and papers are valid. We hope and believe that most of the participants, sponsors and exhibitors already registered will be able to adapt to the new date of the conference. We invite everyone interested to continue submitting abstracts and papers. The conference website remains active and all conference information will continue to be published there. We wish all of you good health, and to get through this difficult period as easily as possible. See you next year in Novi Sad!”
Value chains and regional news
US: Birds Damage Management Conference
The Sunflower Magazine publication of the US National Sunflower Association, in its issue dated March/April 2020, publishes a paper about the Bird Damage Management Conference held last February in Salt Lake City, Utah (see https://www.sunflowernsa.com/magazine/articles/default.aspx?ArticleID=3896), reporting information and learnings from the landscape ecology to the attention of farmers.
The conference itself has been registered and videos are accessible on https://conference.usu.edu/blackbirds/Livestream.cfm with the common password “Starlings2020” The US Sunflower Association funds notably works for birds’ damage management through a project carried out by USDA-APHIS “Efficacy of an Avian Repellent Applied Via a Spraying Drone for Repelling Blackbirds from Sunflower Fields”. Works in progress: research and innovation projects funded by the US NSA in 2020:

France: 31st Meeting of sunflower breeding / 31ème Carrefour de la sélection du tournesol
Since 1977, the French association Promosol supports works on oilseed crops breeding (rapeseed and sunflower) and actions promoting the dissemination of scientific progress. Promosol members are Terres Univia (Interprofessional Organization of the French Oil and protein crops sector), Terres Inovia (Technical Institute of the French Oil and protein crops sector), INRAE (National Institute for Agriculture, Food and Environment Research), and UFS (French seed association for seed companies & plant breeders). Practically, the association defines research priorities of common interest, funds research programs considered to be strategic and disseminates results to breeders and farmers. Promosol organizes the Carrefour de la Sélection du Tournesol every year in February.
The 31st Carrefour of sunflower breeding took place on February 6, 2020 at the INRAE research center in Auzeville-Tolosane, near Toulouse. Bringing together around sixty participants from public research, GEVES (which coordinates varieties registration trials in France), the industry and sunflower breeders; this meeting, moderated by Nicolas Langlade, offered a review of the sunflower crop context and scientific advances of the French research. Luc Ozanne, Sofiproteol director of investments, gave an update on the international oils and proteins market, and the challenges for the sunflower sector. Jim Westwood, professor at Virginia Tech College of Agriculture and Life Sciences, presented research to better understand the specificity mechanisms of germination stimulants in Orobanche. Emmanuelle Mestries (Terres Inovia), and Jean-Noel Aubertot (INRAE) detailed two new models under construction to manage the risk of sunflower diseases. One, Sunflower Pest, analyzes the effects of the dynamics of six sunflower pests on yield development. The other, SimMat Diaporthe, aims to predict phomopsis risk. The latter will be evaluated in field conditions by Terres Inovia in 2020, to validate its usefulness for producers. Concerning the socioeconomic aspects of the new sunflower ideotypes, Mikael Akimowicz (LEREPS) and Nicola Gallai (ENSFEA) presented their research conducted in the frame of the SUNRISE project, at the farm, sector and regional levels. Interviews with different actors with complex interactions were allowed to specify the factors of adoption of varietal innovation in sunflower by French farmers. The participants visited the TPMP platform (Toulouse Plant Microbe Phenotyping) dedicated to high-throughput automated phenotyping under controlled conditions of plant species, which allows to study models of agronomic interest and the associated microorganisms with non-invasive monitoring of plants (by visual imagery, infrared, fluorescence for example), and to simulate precise climatic and environmental conditions. (see: https://www.genotoul.fr/en/portfolio_page/plant-microb-phenotyping/) The Carrefour was an opportunity to follow the progress of four ongoing research projects supported by Promosol:
- RESODIV (Coordinator: Mireille Chabaud, INRAE LIPM Auzeville). This collaborative project between INRAE and the University of Cordoba (Spain) aims to anticipate the circumvention by Orobanche cumana of the genetic resistances of sunflowers. It explores the genetic diversity in species of the Helianthus genus, in order to find new sources of resistance and make resistant material available to breeders, with various defense mechanisms, the accumulation of which will make it possible to create new varieties with lasting resistance.
- DEMELER (Coordinator: Pierre Casadebaig, INRAE AGIR Auzeville) aims to analyze evolutions and variability in the yield of sunflowers in France over the past thirty years, and assess the effects of genetic progress, climate and cultural practices. The project is beginning, and results are expected in 2022.
- HELIADIV2 (Coordinator: Brigitte Mangin, INRAE LIPM): the “Helianthus” network, managed by INRAE with the help of seed companies, aims to multiply and conserve genetic resources of sunflower, and to characterize them from a phenotypic point of view, for different criteria of interest such as tolerance to water stress . This characterization is long and costly when we want to evaluate several hundred sunflower genotypes. To facilitate this work, INRAE proposed to use genomic selection models to predict the behavior of the lines and facilitate the work of varietal creation.
- HELIASEN (Coordinator: Philippe Burger, INRAE AGIR) (see: https://www.youtube.com/watch?v=VZSvgeWuhlw). This project aims to develop phenotyping methods of leaf senescence in sunflower at 3 levels (organ, plant, plot), to differentiate genotypes with contrasting behaviors, but also knowledge on the genetic control of senescence. This project is in collaboration with the Sunrise and Phenome projects and the INTA teams from Castelar and Manfredi in Argentina.
