EVALUATION OF WHEAT TEST LINES / COMMERCIAL VARIETIES AGAISNT KARNAL BUNT (TILLETIA INDICA) UNDER FIELD CONDITIONS

Abstract

Thirty seven test lines / varieties of wheat received from Regional Agricultural Research Institute, Bahawalpur, National Institute for Biology and Genetic Engineering (NIBGE), and Wheat Research Institute (WRI), AARI, Faisalabad were screened in a vivo trial to identify the best source of resistance for breeding programme against karnal bunt of wheat at Plant Pathology Research Institute, Faisalabad during rabi season 2011-2012 and 2012-2013. A susceptible check AS-2002 was also planted after ten entries. Among the test lines / varieties, only one entry, Parwaz 94, was found to be highly resistant. However, 4 lines obtained from RARI, Bahawalpur region were found to be resistance while 4 lines were moderately susceptible. Out of 25 lines received from WRI (AARI), 5 lines displayed resistant, 8 were moderately susceptible and 2 were categorized as highly susceptible. Two lines obtained from NIBGE, Faisalabad exhibited moderately resistant. The disease ranged from 0 to16.9 percent.
