Experiment was conducted to screen different advanced lines and genotypes in line × tester mating design against late blight of tomato caused by Phytophthora infestans. One hundred genotypes were screened during winter season under field condition and data was recorded on 0 - 5 scale at 30, 60 and 90 days in which eleven genotypes were highly resistant, seventeen genotypes were resistant, nineteen genotypes were moderately resistant, twenty four genotypes were susceptible and twenty nine genotypes were highly susceptible. Forty eight F1s were screened along with their parents during rainy season, 2014 under field condition. Out of forty eight F1s, eighteen cross combinations were highly resistant and others were resistant, moderately resistant, susceptible and highly susceptible. The parents namely Solanum peruvianum and Pusa Rohini showed highly resistant and other parents were either resistant, moderately resistant, susceptible or highly susceptible in respect of disease reaction.
