15th International Sunflower Conference Horizontal resistances in sunflower: a review of a workshop at the 15th International Sunflower Conference
15e Conference Internationale Tournesol

A workshop on horizontal resistance at the 15th International Sunflower Conference, held in Toulouse, France, from June 12 to 16, 2000, covered topics including the evaluation, stability and inheritance of resistance of sunflower to Sclerotinia sclerotiorum, Diaporthe helianthi, Alternaria helianthi and Verticillium dahliae. It was notable that research continues into evaluation methodology at the same time as quantitative genetics, use of molecular markers, search for QTL and resistance improvement by genetic engineering.
Résumé
Un atelier sur la résistance horizontale, dans le cadre de la 15e Conférence sur le tournesol tenue à Toulouse, France du 12 au 16 juin 2000, a traité de l’évaluation, la stabilité et l’héritabilité des résistances du tournesol à Sclerotinia sclerotiorum, Diaporthe helianthi, Alternaria helianthi et Verticillium dahliae. On a pu remarquer que les recherches sur les meilleurs moyens d’évaluer la résistance continuent, en même temps que les études de génétique quantitative, la recherche de marqueurs moléculaires et de QTL, et les essais d’amélioration de la résistance par transgenèse.
