Fifteen okra varieties viz. VNR Green, Sungro –319,PAN–2128, JKOH– 7315, Purna, Golden 2436, NS 819, Pankaj, Jaya, Mahyco– 64, Shakti F1 Hyid, Parbhani Kranti, AROH–10, Avantika and Arka Anamika were screened to know their response on the basis of fruit damage scale. Only one variety showed tolerant, ten moderately resistance and four highly resistance in 2012, while during 2013 only single variety showed susceptible while two tolerant, nine moderately resistance and three highly resistance. During 2012 and 2013, VNR Green showed highest no. of fruit damage fruit weight damage and exhibited lowest healthy fruit yield. PAN–2128 showed lowest no. of fruit damage fruit weight damage.
