Abstract
To evaluate the resistance to crown gall in grape rootstocks, cuttings from twenty seven grape rootstocks were inoculated with Agrobacterium vitis Cheonan 493 and size of galls from grapevines was measured in a greenhouse. Tumors were formed in all varieties of grape rootstocks tested in this study and no grape rootstock variety was immune to crown gall. Tumors were found on the stems of all plants tested in '196-17'and '41B' Based on measuring size and weight of galls formedon the stem of grape rootstocks, '779P' was extremely susceptible to crown gall. Some varieties such as 'Gloire', '140R', '101-l4M', '3309C', and '333EM' found to be resistant, while '99R', '1447P', 'Rupestris du lot', '110R', 'Freedom', and '41B'were susceptible and '1103P', '5C', '420A', 'Golia', and '5BB' were moderately susceptible to crown gall.
