Abstract
Potato common scab, caused by Streptomyces scabies , is one of the most important diseases of potato w orldwide. To identify the effect of inoculums levels of common s cab on progeny tubers, field experiments were condu cted at Bangladesh Agricultural Research Institute (BARI), Gazipur, Ba ngladesh using the infected seed tubers of variety ‘Diamant’. There were 6 inoculums levels (0, 5, 10, 20, 50 and 100%) of common scab used as infected tubers. The crop was grown during Rabi season (December-March). Data on percent foliage coverage, plant emergence, scabby tubers and tuber yi eld were collected and analyzed statistically. Results revea led that the effect of different inoculums level of common scab did not influence plant emergence significantly. Percent sc abby tuber ranged 14.13-38.83 by weight. Substantia lly lowest (14.13%) scabby-tuber was recorded in the untreated-control and it was maximum (38.83%) in 100% inoculums level treatment. Regarding yield, although different treatments sign ificantly influenced yield, there was no direct cor relation with the percent inoculums level on yield of the potato. Thi s study suggests that the inoculums from infected s eed tubers can produce disease on progeny tubers the next season a nd inoculum on seed tubers, even those without visi ble lesions, seem to be important in the disease outbreaks.
