Evaluation of Chickpea Genotypes for Resistance to Ascochyta blight

Abstract

Results of the survey carried out in three regions in Ninevah province during the season of 2011 , showed that disease incidence and score of Ascochyta blight of Chickpea wilt were gradually different from region to another. The highly disease incidence and score were in Fyda which reached 70% and 5.8 respectively .Results of isolation and diagnosis showed that the the disease caused Chickpea wilt caused by Ascochyta rabiei (Pass.) Labr .Results of screening twenty genotypes of chickpea for susceptibility to Ascochyte blight indicated that five genotypes were resistant (FLIP05-85C, FLIP 05-113, FLIP 06-156 , FLIP o6-93 and FLIP 06-102C ) six were moderately resistance (FLIP03-72C , FLIP05-57C , FLIP05 -74C, FLIP05-90C و FLIP05-154C and Dijla ),six were susceptible ( FLIP97-220 , FLIP04-22C , FLIP05-18C , FLIP05-44C, FLIP05- 17C and Rafidane) and three were highly susceptible to Ascochyta blight (FLIP05-50C , ILC 263 and local)
