Thirty-three potato clones were evaluated for resistance to the common scab disease of potato caused by Streptomyces scabies by artificial inoculation under greenhouse conditions at Da Lat The isolate GTT4 of S. scabies was used for inoculum production and inoculation. Results obtained indicate that the potato clones differed significantly in the degree of infection expressed as percent of tubers infected, percent of tuber surlace infected and average level of infection (0-'5). On this basis, 12 clones were classified as intennediately resistant, 15 were intennediately susceptible and 6 susceptible. The intennediately resistant clones are recommended for use in breeding potato for common scab resistance.
