Screening of germplasms against powdery mildew of okra (Abelmoschus esculentus)

A field experiment was carried out in kharifseason of 2007 at Parbhani (Maharashtra) to find out the resistant sources against powdery mildew of okra [Abelmoschus esculentus (L.) Moench]. The mean disease incidence on cultivated okra varieties/germplasms was 56.12–62.46%. Mean foliage disease severity (PDI) in okra varieties at 50, 65 and 80 days after sowing (DAS) ranged from 5.16–10.20, 12.75–22.85 and 49.80–59.35, respectively. On the basis of overall mean foliage severity, none of the variety/germplasms was recorded immune and resistant; however, 8 varieties (PBN OK-4, PBNOK-5, PBN OK-6, PBN OK-8, PBN OK-9, AOH-23, Surya and NOH 100) showed moderate resistant and 22 moderate susceptibility.
