Abstract:

Cultivation of resistant genotypes seems to be the best alternative and most economical to keep the activity of the pathogens under control. Thirteen bottle gourd genotypes were evaluated against the leaf spot disease caused by Alternaria cucumerina and anthracnsoe under natural epiphytotic conditions. The genotype Arka Bahar registered lowest PDI (24.87%) followed by the genotypes Bot G-1 (28.87%) and Bot G-2 (30.13%) and BL-4 (30.96%). Maximum PDI of 45.01 was noticed in the genotype BL-10 followed by the genotype BL-5 (41.82) and Bot G-4-1 (39.45). The genotype Arka Bahar registered lowest Per cent Disease Incidence (26.50) for anthracnose followed by the genotype BL-9 (28.20). Maximum Per cent Disease Incidence of 53.24 was noticed in the genotype P cyl L BL-3 followed by the genotype BL-4 (50.00) and Bot G-4-1 (48.09). Therefore the genotype Arka Bahar and BL-9 were found to be moderately resistant to the disease. Genotype Arka Bahar was found to be moderately resistant and remaining genotypes were susceptible to the disease.
