Key Note speaker Plant resistance and architecture for protection of pulses against biotic stresses
Prod 2019-88l BAP GEAPSI INRA DOCT; National audience; Major diseases and pests, such as root rots, ascochyta blights and aphids, are limiting factors to cool season pulse production in many countries worldwide, especially in Europe. In the context of pesticide reduction, plant genetic resistance and architecture are main traits that can be mobilised in breeding for disease and pest management. Knowledge of quantitative resistance to major diseases and pests of pea and faba bean in France has benefited from the development of sequenced genomes and massive SNP markers [1], which have recently been highly valuable to identify candidate genes controlling resistance. Fine mapping and sequencing…

Identification of genes underlying frost tolerance within a pea QTL
Prod 2019-88dd BAP GEAPSI INRA; National audience; Seeding legumes in autumn would allow increasing and regulating yield, but requires to improve the level of frost tolerance in varieties, which motivates the interest in deciphering the genetic determinism of this trait. In pea (Pisum sativum L.), this character is controlled by a few quantitative trait loci (QTL) that were identified by the analysis of RIL populations derived from contrasted genotypes, such as Champagne (Ch, tolerant) x Térèse (Té, sensitive), or by association analysis [1,2,3]. We study a QTL located on the pea linkage group 6 (WFD6.1), which accounts for a large part of frost tolerance variability, making it a choice tar…
