dc.description.abstract | Susceptibility of fifteen local and introduced sweetpotato germplasm to Rhizopus soft rot disease caused by Rliizopus stolonifer and Rliitopus oryzae was tested in 1999 and 2000. Roots were surface sterilised, wounded and inoculated with 9 nun diameter agar plugs removed from the edge of actively growing two-day old cultures of the test pathogen. Infection was evaluated by measuring the diameter and depth of the internal lesion developing around the inoculation wound under room temperature for 48 hours. The germplasrn exhibited wide variability in susceptibility to infection. The cultivars Maria Angola. Santa Amaro. SPK 0l3. KEMB 10 and Marooko consistently developed smaller lesions compared to other cultivars, and were considered more resistant to Rhizopus soft rot disease. The cultivars Naveto, Tainung 64, KEMB 23 and YIlI/shu 1 consistently developed larger lesions compared with other cultivars and. were considered more susceptible. Variability in susceptibility expressed by the germplasm shows the possibility of using host resistance as a means of controlling Rhizopus soft rot disease in sweetpotato root tubers. | en |
