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…
Comparative genome-wide-association mapping identifies common loci controlling root system architecture and resistance to Aphanomyces euteiches in pea
BAP GEAPSI INRA; International audience; Plant architecture can contribute to decrease plant susceptibility to pathogens by favoring mechanisms leading to infection escape or increased tolerance. Combining genetic resistance with architectural traits that can negatively impact disease development is thus a strategy of great interest to reduce epidemics. Until now, most strategies exploiting plant architecture have focused on the aerial parts of plants. Few studies have been done on the identification of root system architecture (RSA) traits limiting root disease development and even less on their use in breeding. Aphanomyces euteiches, a soil-borne pathogen infecting roots, is a major limit…
