Abstract


Wheat has been one of the first domesticated food crop and important food grain source for humans. Sixty wheat advanced lines/varieties received from different Research Institutes of the Punjab, Pakistan were screened for genetic potential against Bipolaris sorokiniana, a pathogen of wheat leaf blight in two consecutive years under inoculated conditions. Before sowing, the seeds were inoculated with the pathogen. Considering the lower percent of disease and higher vigour index, 12 wheat lines, namely 8C006, 8C007, 9C033; 9C035, 9C036, 7C002; 088186, 088195; 076395, 076309, V. 07142 and V.05068 were identified as tolerant against the pathogen. Among the four fungicides, Score 25% EC and Craze 80% WP were found the most effective as seed treatment to control the disease.
