Tomato is one of the most extensively cultivated vegetables and is a rich source of nutrients such as vitamins, antioxidants and minerals for a balanced human diet. World over, early blight (EB) caused by Alternaria solani Sorauer is limiting tomato production and causes great losses. In total, 350 tomato genotypes from ICAR-National Bureau of Plant Genetic Resources (ICAR-NBPGR), New Delhi were evaluated for early blight resistance under epiphytotic conditions at ICAR-Indian Institute of Vegetable Research (ICAR-IIVR), Varanasi. Augmented design with five released varieties as checks was the experimental design followed. EC705445 gave highly resistant (HR) reaction with 0.86 percent disease index (PDI). EC0027336, EC0114504 and EC0027932 gave resistance (R) reaction. Another fourteen genotypes gave moderately resistance (MR) reaction. Seven genotypes (EC705445, EC0013112, EC0026104, EC699717, EC695040, EC000586 and EC0111086) that gave either HR or R or MR reaction under field conditions were further screened for the disease reaction under artificial conditions and none of the genotypes shown either HR or R or MR reaction.
