Abstract
In Pakistan, potato (Solanum tuberosum) is amongst the foremost cash crops for the farming community. Common scab (Streptomyces sp.) is one of major disease, which reduces the price, and market value of potato tubers. The present study was designed to determine the status of common scab in selected potato growing areas. This survey was directed to record the occurrence and intensity of common scab of potato in the major potato producing areas in districts of Punjab, namely Sialkot, Lahore, Kasur, Sahiwal, Okara, Pakpattan, tehsil Depalpur, Faisalabad Taxila and Hazro during the harvesting of potato in 2017-18. Overall, 456 potato fields were surveyed for data collection. It was noticed that the maximum common scab occurrence was recorded in Sahiwal followed by Okara, Kasur, Pakpattan, Faisalabad, Lahore, tehsil Depalpur and minimum in Sialkot and Hazro. Disease incidence was also checked on the current varieties of potato used for sowing, highest disease frequency was observed in var. ‘Kuroda’ and var. ‘Santi’ so these two varieties were highly susceptible while var. ‘Diamant’ and var. ‘Cardinal’ were detected as medium susceptible while var. ‘Lady Rosita’ and ‘var. Asterix’ were detected as highly resistant to common scab. The resistant and moderately susceptible varieties are therefore recommended for cultivation and in developing new resistant cultivars
