G. rostochiensis
Identification of pathotypes • Studies on the identity of species and pathotypes have been carried out since the middle of the 1970s until present time. • The initial studies on pathotypes were made according to Kort et al., 1977. • Under Norwegian conditions all pathotypes of G. pallida and most pathotypes of G. rostochiensis except Ro1 are considered virulent on andigena-resistant potatoes. • In the 1980s a simpler method was introduced using resistant potato cv. Saturna (resistant to Ro1, Ro4) with the susceptible variety Kerrs Pink as control. Populations developing on cv. Saturna are classified as resistance breakers.
