The experiment was demonstrated with six treatements consisting of 0, 4, 10, 20, 50, and 100% black scurfed seed tubers to determine their effect on progeny tubers. It was found that infected inoculum had positive impact on progeny tubers. In general, with the increasing of inoculum levels, infestation on progeny tubers increased gradually.

To observe the rate of transmission of inoculums of R. solani in progeny tuber
The experiment was carried out at BSPC, Debigonj, Panchagarh, with black scurfed seed tubers (2-4 rating scale) of the variety, Crdinal. The unit plot size was 3.0×3.0 m and spacing 60×25 cm.The experiment was cosnisted with six treatments Viz, 0, 4, 10, 20, 50, and 100% infected tuber. Apparently healthy tuber treated as control (0%). Recommended doses of fertilizers were used. Data were taken on plant emergence; stem canker, black scurf tuber by number and weight and total yield.

Infected inoculum had positive impact on progeny tubers. In general, with the increasing of inoculum levels, infestation on progeny tubers increased gradually and affects the yield and quality. So, it is necessary to avoid use of scabby tuber as seed potato in order to produce healthy seed production.
