GENETIC POTENTIAL OF COTTON GERMPLASM FOR MANAGEMENT OF BACTERIAL BLIGHT DISEASE

Abstract

In present study fifteen varieties of cotton (FH-114, Bt-121, SLH-336, Kirn, SLH Bt-6, Bt-666, CIM-595, FH-113, Bt-MK2, Bt-222, Bt-457, Bt-7, SLH-317 and Bt-986) were cultivated in research area of the Department of Plant Pathology University of Agriculture Faisalabad during 2012 to determine their genetic response against bacterial blight under randomized complete block design (RCBD). Results showed that none of variety showed immune response against disease while FH-114, Bt-121 and SLH-336 showed moderately resistance to bacterial blight with 15, 17 and 20% disease incidence respectively. While Kirn, SLH Bt-6, Bt-666, CIM-595, FH-113 and Bt-MK2 showed moderately susceptible behavior with (29-38%) disease incidence. The varieties SG-1, Bt-222, Bt-457, Bt-7, SLH-317 and Bt-986 showed highly susceptible response with (41-56%) disease incidence against the disease.
