| Abstract: | Summary Tubers were obtained from 80 glasshouse-grown seedlings of each of twelve progenies, inoculated withPhoma foveata Foister, and the mean percentage of infected tubers recorded. There was a good correlation (r=0.798) between this assessment and that made previously on field-grown tubers of eleven of the progenies. A gangrene test
on glasshouse-grown tubers is suggested as a more rapid means of identifying progenies with useful levels of resistance. |
