Abstract
A collection of 64 wild Cicer accessions from seven different species (C. bijugum K.H. Rech., C. cuneatum A. Rich., C. echinospermum Davis, C. judaicum Boiss., C. pinnatifidum Jaub. & Spach, C. reticulatum Ladiz., and C. yamashitae Kitamura) were screened for resistance to Ascochyta blight (Ascochyta rabiei (Pass.) Lab) by creating artificial epiphytotic conditions in the field. Resistance was identified in accessions from six wild Cicer species. Variation for resistance within accessions of C. bijugum, C. echinospermum, C. judaicum, C. pinnatifidum, C. reticulatum and C. yamashitae was recorded. All the accessions of C. cuneatum were highly susceptible to Ascochyta blight. Resistant accessions of C. echinospermum and C. reticulatum belong to primary gene pool of Cicer species and can be crossed easily with Cicer arietinum and fertile hybrids can be obtained.
