ABSTRACT

Evaluation of germplasm against chickpea blight (Ascochyta rabiei (Pass) Lab) is an effective method to characterize the resistance and susceptibility level of gram varieties. In present study, 48 varieties/lines collected from Ayub Agriculture Research Institute, (ARRI) Faisalabad were screened by artificial inoculation, at research area of Plant Pathology, University of Agriculture, Faisalabad. Among 48 genotypes, 16, 8, 3, 10, 11 were found highly susceptible, susceptible, moderately susceptible, resistant and moderately resistant, respectively.  The lines showed highly susceptible reaction were: K-97006, K-97007, K-98009, K-94002, K-98014, K-98012, K-52721, K-60028, K-93001, K-92030, K-96022, D-CM98, D-CAM68, D-91013, D-97074, D-96022 and Punjab-1(check), while, genotypes showed susceptible reaction were viz: K-95058, K-60016, K-60034, K-60048, D-91224, D-03019, D-05028 and D-03006. There were only 3 lines (K-98007, K-50076 and K-95041) displayed moderately susceptible response. Whereas, K-96033, K-89169, K-90395, D-91017, D-89044, D-05006, D-96018, D-86030, D-96032, D-1CC-5127 and D-03009 exhibited moderately resistant response against chickpea blight. While lines, K-60013, K-98008, D-97092, K-96001, K-96022, D-91055, D-90272, D-96050, D-Pb2008 and D-Pu502-362 showed resistant reaction. Results clearly mentioning that most of the genotypes collected from ARRI were susceptible against Ascochyta blight.
Key words: Screening, chickpea, genotypes, Ascochyta rabiei.
