Cotton is a very important commercial crop of India and to the world. Essentially used for fibre, fuel and edible oil and various other purposes. It is important because it is cash crop to the farmers. Out of 30 diseases known to occur in cotton crop from time to time, the bacterial blight is the most wide spread and destructive disease reported to cause yield losses of about 10 to 30 per cent. In this experiment different cultivars/ entries were screened against the bacterial leaf blight disease. Infester row of susceptible check LRA 5166 was grown alternating every four rows of the test entries. The maximum PDI of LRA 5166 was 20.0 PDI was observed. Artificial inoculation was made twice by preparing the spore suspension of BLB. Total 44 entries were screened through artificial inoculation, from these entries viz., GN Cot. 22, GISV 272, GSHV 180 and G. Cot.20 (LC) were moderately resistant against the bacterial leaf blight disease whereas, in case of Alternaria leaf spot disease, three entries viz., GISV 272, GSHV 180 and G. Cot. 20 (LC) were observed as resistant against the disease. Rests of the entries were free from the infection.
