Symposium on Sunflower and Climate Change

The International Symposium on Sunflower and Climate Change was organized in the frame of the SUNRISE project, by INRA Toulouse (Institut National de Recherche en Agronomie) and the French technical c...

In brief

In an unprecedented effort - 8 years project, investment of €21m, 16 partners including 9 public laboratories with a specific investment of INRA, 6 companies involved in sunflower breeding and the ...

The Project

In a context of climate changes and of world increasing demand for oilseed production, it is crucial to improve resistance to drought and yields of sunflower crops in such conditions. To improve ge...

Project partners set up more than 6,000 plots in 2017

  • Discovery experiments on the NAM-DRR

In 2017, the genetic design of 1500 genotypes (NAM-DRR) set up in the SUNRISE project is again tested in the field on 4 trials, with a total of more than 6,000 plots. In order to test this genetic design in contrasting environments, one of these tests was carried out in Chile (a very dry Mediterranean climate) by Syngenta in the winter 2016-2017, with two modes of driving: Throughout the crop cycle and a pipe where water stress started at the onset of flowering.

  • Validation experiments on GWA 491

Efforts to validate the effects of genomic areas implicated in agronomic traits identified on the GWA genetic design including 491 genotypes (studied from 2013 to 2015) are continuing: this year, 3 devices are implemented on a total of 15 trials. Each device has about 20 genotypes. The characteristics studied are yield, crop index (ratio of grain weight to weight of vegetative parts) and tolerance to drought.

  • Experiments on the Heliaphen phenotyopage platform

7 SUNRISE trials are also conducted on the Heliaphen phenotyping platform of Inra Occitanie-Toulouse.
