Abstract

Ascochyta blight is the most important limitalive disease reducing production of chickpea in many areas. The resistance lines were considered as the best way to control the disease. So identification of suitable resistance sources against population of pathogen in each area is important. In this study chickpea germplasm of Ferdowsi University was eva luated against six pathotypes of the pathogen. Five hundred-seventy accessions were cultivated in an augmented design with ten blocks and sixty-seven rows. Plants were inoculated with mixture suspension sporesofsix pathotypes in five tosevenleaves stage. Suitablehumidityand temperature were provided using amist irrigation system. When the susceptible lines (ILC1929 andILC263) died completely, disease severitywas scored on a scale of 1to9, where 2 and 3 =resistance, 4 and 5 = moderately resistance, 6 and 7 = moderately susceptible and 8 and 9 = highly susceplible. 2, 25, 32and 41%of the accessions were divided in those groups respectively. The percentage of Kabuli type in the resistance groups was more thanDesi type, but in the susceptible groups, Desi type was more frequently observed than Kabuli type. Only one Desi (MCC523) and five Kabuli accessions (MCC54,MCC133, MCC3.11 , MCC142 and MCC331) were resistant at different growing stages against six pathotypes of ascochyta blight.
