Prospecting for sources of resistance to ascochyta blight in wild Cicer species

Abstract

A collection of 114 Cicer accessions including 95 wild Cicer accessions from four different species (C. bijugum K. H. Rech., C. echinospermum P. H. Davis, C. pinnatifidum Jaub. & Sp. and C. reticulatum Ladiz.) was screened in glasshouse trials for resistance to ascochyta blight (caused by Ascochyta rabiei (Pass.) Lab.). Resistance was identified in accessions from all four wild Cicer species. There was variation for resistance within accessions of C. echinospermum, C. pinnatifidum and C. reticulatum, with only C. bijugum containing accessions in which all plants were completely resistant. Resistant accessions from C. echinospermum and C. reticulatum may offer accessible sources of resistance..
