Abstract:
Early blight of tomato, caused by Alternaria solani (Ellis and Martin) Sorauer, is a serious disease in warm and humid regions and in semiarid areas where frequent and prolonged night dew occurs. In this study, 129 tomato genotypes under field conditions were screened at Research Farm Plant Pathology, in the Division of Plant Pathology, Faculty of Agriculture, Sher-e-Kashmir University of Agricultural Sciences and Technology-Jammu, Chatha during the year 2017-18 and 2018-2019 against early blight Eleven genotypes (Money Maker, EC-170047, EC -320574-1, EC-617047, EC -310301, EC -310303, EC -520078, EC -521067-B, EC -523351, EC -620406, EC -645179-D) were found highly resistant while twenty genotypes were found resistant (Punjab Chhuhara, Flora Dade, EC -501574, EC -317641, EC -3176-1, EC -109746, EC -163611, EC -164838, EC -620515, EC -515014, EC -169966, EC -320518, EC -620510, EC -538156, EC -620361, EC -620376, EC -320387, EC -620395, EC -163605, EC -251750,) and three genotypes (Pusa Ruby, C-26-1, EC -170089) were found highly susceptible.
