Early blight disease is a serious threat to tomato cultivation in India causing severe loss in yield due to pre and post harvest losses. Apart from host environmental conditions are one of the major factors in disease development. Screening of different lines were done considering climatic conditions like temperature and relative humidity during years 2012 and 2013 and their responses for Alternaria disease symptoms was recorded as percent diseases index (PDI) at regular intervals continously for two years for different tomato cultivars/lines. Different lines were categorised on the basis of their PDI values and susceptible and resistant lines were selected among 77 lines during both years. None of the varities registered highly resistant reaction but the varities were resistant to the disease in both the years
