Abstract: Screening of Gossypium hirsutum varieties/genotypes against Alternaria leaf spot and bacterial leaf blight diseases under natural and rainfed field conditions was conducted during kharif seasons of 2014-15 and 2015-16 at Regional Cotton Research Station, Navsari Agricultural University, Maktampur farm, Bharuch, Gujarat. Two cotton genotypes i.e. GSHV-159 and GBHV-184 were found disease free; ten varieties/genotypes viz., G.Cot.-34, G.N.Cot.-26, GBHV-177, GBHV-180, GBHV-183, G.N.Cot.-22, GBHV-185, GBHV-187, GBHV-193 and GBHV-202 as resistant, while the variety G.Cot.-16 were found moderately resistant against Alternaria leaf spot disease. Cotton genotype GBHV-193 was found disease free; nine varieties/genotypes viz., GSHV-159, G.N.Cot.-26, GBHV-177, GBHV-180, GBHV-183, G.N.Cot.-22, GBHV-184, GBHV-185 and GBHV-202 as resistant, whereas three varieties/genotypes viz., G.Cot.-34, G.Cot.-16 and GBHV-187 were found moderately resistant reaction against bacterial leaf blight disease.
