Screening for resistance to ringrot corynebacterium michiganense pathovar sepedonicum in potatoes

Screening for resistance to ringrot corynebacterium michiganense pathovar sepedonicum in potatoes

Vaxtskyddsnotiser 51(2): 47-55

A total of ca 150 potato varieties were examined with regard to their resistance to ringrot, during several years since 1969. Seed potatoes were inoculated with a pure culture of the bacteria, and then grown outdoors under normal field conditions. Initial readings were taken from random samples of harvested tubers which had been stored for at least 6-7 months. Tubers were sliced longitudinally and examined visually. Examinations showed that ringrot attack in the reference variety, Bintje, varied greatly between years. Several clones from the Swedish Seed Associations' plant breeding material had no visible attack, and these were taken for eggplant inoculation. The latter tests revealed virulent ringrot bacteria in those varieties that had shown resistance during the years Bintje had suffered strong attacks. None of the varieties examined showed complete resistance. Furthermore, none of the "resistant" clones tested had sufficient qualities to warrant their inclusion in the official Swedish List of Cultivars, 1986-87. Several new high susceptible varieties i.e. Elin, Matilda, Rosamunda, Silla and Stina, have, however, been included in the list. Two older cultivars, Alpha and Elsa, did in fact show very good resistance to ringrot. They are, however, not included in the national list of cultivars.
