The experiment was carried out in the greenhouse from March to September 2021 with 4 treatments and 3 replications laid out in randomized complete block design (RCBD). The results showed that all three types of rootstocks were compatible with the grafted scions and gave a high survival rate after grafting (85.56 - 91.11%). The percentage of grafted plants infected by bacterial wilt (Ralstonia solanacearum) was very low (0-2.81%) while 47.43% of ungrafted plants were infected. Although grafted plants have lower values of plant height and stem diameter than ungrafted plants, the fruit set ratio, number of fruits per plant and yield of the grafted combinations are still higher 2-2.5 times. Therefore, EG203, RADO205 and TLP9999 rootstocks are perfectly suitable for cultivation in off-season conditions to minimize bacterial wilt infection and increase yield for cherry tomatoes.
