↵1. Key to table. S = susceptible, galls and egg masses noted; T = tolerant, some galls but no egg masses; R = resistant, no galls and no egg masses. First figure in parentheses refers to gall rating: 0 = no galls; 1 = from one to two galls; 2 = three to 10 galls; 3 = 11 to 30 galls; 4 = 31 to 100 galls; 5 = more than 100 galls per root system. (+) denotes that two or more egg masses with potentially viable eggs were found. (0) denotes that no egg masses were found.
