Abstract:

An experiment was conducted for evaluation of tomato genotypes both in uninoculated field conditions and by artificial inoculated controlled conditions against early leaf blight at Research farm, SKUAST-Kashmir. A total of 50 tomato genotypes were screened under uninoculated field conditions. Among these germplasms, 07 test lines viz., 2014/TODHYB-7, 2015/TODHYB-2, 2016/TODHYB-4, 2016/TODHYB-6, 2016/TODHYB-7, 2016/TODVAR-10 and 2016/TODVAR-12 exhibited complete resistant against early blight and 14 lines viz., 2014/TODHYB-1, 2014/TODVAR-3, 2014/ TODVAR-1, 2014/TODVAR-4, 2014/TODVAR-6, 2015/TODVAR-1, 2016/TODVAR-3, 2016/ TODVAR-4, 2016/TODVAR-6, 2016/TODVAR-7, 2016/TODVAR-8, 2015/ TOINDVAR-2, 2015/TOINDVAR-3 and 2015/TOINDVAR-5 were found moderately resistant. The rest were found to exhibit moderately susceptible to susceptible reaction. The 21 genotypes found to be moderately resistant to resistant under field conditions were further screened under artificial inoculated controlled conditions. Three test lines (2016/TODHYB-4, 2016/TODHYB-7, 2016/TODHYB-6) were found resistant and six test lines (2016/TODVAR-10, 2016/TODVAR-3, 2015/TODHYB-2, 2014/TODHYB-7, 2016/TODVAR-6, 2016/TODVAR-12) were exhibited moderately resistant response. The rest were found to exhibit moderately susceptible to susceptible reaction.
