Training course “Phenotypic plasticity and norms of reaction modelling”

Course date: October 5-7, 2021

This is one of three B4EST training courses to deliver key scientific results and tools via hands-on training events, targeting researchers, Master and PhD students and post-doctorate fellows. The course is co-organized by the SLU Breeding Network and the SLU Industry Research School of Forest Genetics, Biotechnology, and Breeding.

The training course is organized into three consecutive days, including six lectures, plus several case studies about 75 minutes per lecture/case study (3.5-4 hours per day), using Zoom as a meeting format. Some lecturers will give their lecture from North America and hands-on demonstration with R will be included in some lectures.

The following course instructors will hold the course: Harry Wu/Zhiqiang Chen (SLU, Sweden), Tongli Wang (UBC, Canada), Tore Skrøppa/Arne Steffenrem (NIBIO, Norway), Laurent Bouffier (INRAE, France), Philippe Rozenberg (INRAE, France), Marie Denis (CIRAD, France), Jean-Marc Gion/Alexandre Bosc (CIRAD/INRAE, France), Maurizio Marchi (CNR, Italy).

B4EST Stakeholder Meeting: Research on Maritime Pine resilience and bioeconomy

The B4EST consortium, in collaboration with the IEFC, the INRAE  and the FCBA, is organizing a symposium on latest studies on maritime pine resilience and bioeconomy, November 19, 2021 at the INRAE de Pierroton premises in Cestas (Bordeaux), France. Salle Airial from 9:30 to 17:00.

This event aims to review and discuss the latest research on the resilience and the bioeconomy of maritime pine, focusing on the maritime pine improvement programme. It is organized as part of a series of international events supported by the B4EST project, “Breeding for adaptation: for productive, sustainable and resilient forests under climate change”. It is intended for all stakeholders in the maritime pine sector who wish to gain relevant information and interact with research experts to learn more about the work in progress. This symposium, in French, will also be an opportunity to get an overview of ongoing initiatives abroad, such as in Galicia with the selection of material resistant to pinewood nematode (PWN).

Web Conference on Genetic Basis of Quantitative Traits and Multitrait Association.

*Please note, this training course is postponed until early 2022*

The B4EST consortium, through the University of UPPSALA, INRAE, University of OULU and Consiglio Nazionale delle Ricerche, in collaboration with EVOLTREE, is hosting a web course from September 21-24, 2021. The course will present the latest extensions of Fisher’s infinitesimal model, in particular the omnigenic model and discuss their implications for breeding, association studies and evolutionary inferences.

The course will cater to PhD students and postfoctoral fellows with background in population genetics and/or quantitative genetics.

The conference will take place via zoom To register please send an email to Martin Lascoux If you have problems with this address, please contact communications @

General course plan: Each day we shall have 2 hours lecture in the morning and 2-3 hours tutorial in the afternoon. A detailed schedule will be sent to participants later on.

Panel of Experts (preliminary list): Santiago C. González-Martínez, Juliette Archambeau, Kalle Leppälä, Tanja Pyhäjärvi, Alina Niskanen, G. Giuseppe Vendramin, Antoine Kremer, Martin Lascoux


• Day 1: From the infinitesimal to the omnigenic model

• Day 2: The omnigenic model and evolution of quantitative traits architecture

• Day 3: Consequences of the omnigenic model for genomewide, multi-traits association: what we already know and what needs to be known

• Day 4: Estimating the genome-wide contribution of selection to temporal allele frequency change: principle and an application to forest trees

First EVOLTREE Conference 2021: Genomics and Adaptation in Forest Ecosystems

The first EVOLTREE Conference, hosted by WSL Birmensdorf (Switzerland) from 14-17 September, 2021, focuses on the genomics and adaptation of trees and interacting species from evolutionary, demographic, and ecological perspectives.

Contributions that apply innovative approaches and consider the relevance of their research in the context of biodiversity conservation through natural dynamics or silvicultural interference are welcome.

Registration and abstract submission is now open!

EVOLTREE is a European network of research institutions and universities engaged in studying the evolution and functioning of forest ecosystems, in particular trees as the foundation species in forest stands. A prime topic in the face of ongoing climate change is to elucidate how trees, together with their associated organisms such as mycorrhizal fungi, respond to rapid environmental changes.

For more details, visit our conference website:

Please note that due to the COVID-19 pandemic, for now you can register only for the online conference. In early June 2021, decisions will be made if and how many attendees can participate on-site (subject to government travel restrictions that may change at short notice). You will then be able to acquire an additional on-site package.
