Caractérisation des pathotypes ďHeterodera avenae en France: influence de la période de culture slir le pouvoir discriminant de cultivars ďAvena sativa et différences dans la capacityéàfo̊rmer des femelles1

Abstract: La caractérisation des pathotypes ďHeterodera avenae en France montre le rôle discriminant de plusieurs cultivars ďAvena sativa. Malgré un allongement de sa période de culture par un semis en automne (mois de decembre), le cultivar de type printemps Noire de Moyencourt est un hôte mediocre pour les pathotypes Fr 1 et Fr2 mais excellent pour les pathotypes Fr3 et Fr4. Cette relation entre les nématodes et le végétal paraît ďordre génétique, car les résultats sont confirmés par des données obtenues en conditions… Show more

“…In contrast to that discussed by Al-Hazmi et al (2001), Mediterranean populations of H. avenae differed in virulence to oat cultivars according to their winter or summer physiological type, as previously demonstrated for French pathotypes located in Southern France (Rivoal, 1977;Rivoal & Person-Dedryver, 1982). The Indian E84 population of H. lipjevi exhibited a virulence spectrum to barley genes different from those of H. avenae and H. latipons populations presently tested.…”

“…In spite of consistent controlled conditions, a substantial variation in the production of adult females was observed between nematode populations, inferred from great differences in their intrinsic capacity to develop. This biological trait has been already observed for French pathotypes of H. avenae using the same Petri dish technique (Rivoal & Person-Dedryver, 1982) and statistically demonstrated for a wider set of CCN populations using the tube technique (Rivoal et al, 2001).…”

“…Le plus important concerne l'existence de différents pathotypes du nématode répertoriés en France (R IV O AL , 1977) se multipliant plus ou moins sur plantes dépourvues de gènes de résistance vis-à-vis d'H. avenae (RIVOAL, 1977 ;PERSON & DOUSSINAU1_T, 1978 ;RIVOAL & PERSON-DEDRYVER, 1982 (1982).…”

“…Pathotypes of H. avenae which lacked the ability to reproduce on oats, had a higher reproductive fitness on common hosts than two more widely virulent pathotypes (Rivoal and Person-Dedryver, 1982). Aspects of these interactions which lead to problems with classification and recognition of pathotypes have been discussed above.…”
