Abstract


The present experiment was performed to evaluate the cotton germplasm against bacterial blight of cotton under field conditions. For this purpose, nine Bt, (Bt Ali Akbar 802, Bt-FH 177, Bt-FH 182, Bt-NIBGE 2, Bt-CM 615, Bt-CRS 2007, Bt-CM 616, Bt-FH169, Bt-IUB 222,) and 3 non Bt, (Sindh 1, CRIS134 and CIM 573) varieties of cotton were used. The screening trial was conducted for two years under field conditions. six varieties showed moderately resistant response i.e. Bt-CM 615, Bt-CRS 2007, Bt-CM 616, Bt-IUB 222, Non Bt-Sindh 1 and Bt-FH 177 with disease rating 4. Three varieties (Bt-Ali Akbar 802, Non Bt-CIM 573 and Bt-NIBGI 2) expressed moderately susceptible response with rating 5. Two varieties (Bt-FH 182 and Bt-FH 169) showed susceptible response with disease rating 6 while Non Bt- CRIS 134 expressed highly susceptible response with disease rating 7.

Key words: cotton, bacterial blight
