Abstract

Roots of eighteen potato genotypes, differing in tolerance of G. pallida, grown from tuberpieces on agar in Petri dishes. Juveniles of G. pa ida were inoculated directly onto root tips. Root length was measured at various times after inoculation. Inoculation reduced root growth within one day. At later stages, genotypes differed strongly in growthof inoculated roots. Between four and seven days after inoculation, growth of inoculated roots was not significantly correlated with growthof untreated roots, and was only poorly correlated with tolerance assessed in the greenhouse or in the field. However, multiple regression analysis revealed that the tolerance of the tested genotypes was associated with both the rate at which they induced hatching and the growthof roots after inoculation. The combination of these two variables accounted for high percentages explained variance.
