Abstract

Identification of RESISTANCE sources against ASCOCHYTA BLIGHT pathotypes is necessary to use in CHICKPEA breeding programs. Plant breeders accept SCREENING of crop germplasm as useful gene pool against biotic and abiotic stress. Ascochyta rabiei is one of the most important constraints to CHICKPEA production in the most area of world especially in Iran. In this study, reactions of 420 CHICKPEA accessions and 97 lines and cultivars from Ferdowsi University of Mashhad were evaluated to find resistant sources against six pathotypes of Ascochyta rabiei by artificial infection using mix spore suspension in field and greenhouse conditions, during two years (2003 and 2004). In first step, the seeds were sown in field and inoculated using mix spore suspension of six pathotypes in five to seven leaf stages. The humidity and the temperature were regulated using mist irrigation system during a week after inoculation to distribute disease in field. The disease severity was scored on a scale of 1 to 9, when susceptible lines death. In this step 63 accessions with the scales 2 to 4 showed high resistant levels against the pathotypes. These accessions were inoculated again by the spore suspension in greenhose in different developmental stages i.e., planting, flowering and podding. The diseases symptoms were scaled two weeks after each step of inoculation. Nine accession showed high resistant level in greenhouse. The average of disease severity was higher in greenhouse compared to that of the field. Differentiation of resistant and susceptible accessions was correctly done in podding stage. According to filed and greenhouse evaluations two desi accessions (MCC 54 and MCC 523) and six Kabuli accessions (MCC 496, MCC 133, MCC 299, MCC528, MCC 3.11 and MCC 142 were resistant against six pathotypes of ASCOCHYTA BLIGHT. These accessions can be used as resistant sources in CHICKPEA breeding programs.
