Field Evaluation of Bottle Gourd Genotypes for Resistance against Alternaria Blight in Western Rajasthan

Seventeen bottle gourd genotypes such as Pusa Naveen, Pusa Samridhi, Udaipur Local, Pusa Santushti, Pusa Sandesh, PSPL, Chomu Local, Azad Harit, Panchmahal Local, Arka Bahar, Thar Samridhi, PN-22, DBG-5, DBG-6, Jodhpur Local, IC-567538 and Sriganganagar Local were evaluated for resistance against Alternaria blight during rainy season of 2011 and 2012 under fie ld conditions. Among them, 06 varieties such as Pusa Naveen, Pusa Samridhi, Pusa Sandesh, Pusa Santushti, Arka Bahar and PSPL showed moderately resistant having 4.87–8.62% disease severity and 10 genotypes were categorized as moderately susceptible (13.0 to 24.75%) while one germplasm ‘Chomu Local’ proved susceptible against this disease. p>
