Abstract: One hundred and seventy three germplasm lines/varieties of chickpea received from various research organizations were screened for the sources of resistance against chickpea blight disease (Ascochyta rabiei (Pass) Lab) by artificially inoculating the germplasm under a plastic tunnel where temperature, ranged from 8-24⁰C and humidity was maintained above 80% by sprinkling fresh water. Out of 61 lines received form Pulses Research Institute, Faisalabad 3 lines viz., 03039, 03041 and 03053 exhibited highly resistant response while 11 lines viz., 03001, 03002, 03011, 03016, 03020, 03023, 03024, 03035, 03040, 03044 and 03045 displayed resistant reaction. The rest of the lines displayed moderately susceptible to susceptible reaction. Out of 80 lines received from Nuclear Institute of Agriculture and Biology, Faisalabad 5 test lines i.e. 03115, 03131, 03133, 03143 and 03159 were found to be highly resistant while 16 test lines viz., 03108, 03126, 03127, 03153, 03156, 03157, 03161, 03162, 03169, 03170, 03172, 03173, 03174, 03177, 03178 and 03180 were found resistant against A. rabiei infection. Similarly out of 90 test germplasm lines/ cultivars received from Arid Zone Research Institute, Bukhar 3 lines viz., 93A-086, 93A-111 and 93A-3354 exhibited highly resistant response while 5 lines viz., 91A-016, 92A-792, 92A-117, 96A-4504 and NES-98K4, displayed resistance response against A. rabiei infection. These resistant sources can further be exploited in breeding programe for the development of disease resistant commercial cultivars.
