Abstract
Twenty-five (25) genotypes of five wild Cicer species (Cicer judaicum, Cicer bijugum, Cicer cuneatum, Cicer echinospermum and Cicer reticulatum) were screened for resistance to ascochyta blight disease caused by Ascochyta rabiei, by artificially inoculating the germplasm under glasshouse. Highly significant effect (P<0.01) was observed on their reaction to three pathotypes of A. rabiei (Mos02 ‘pathotype III: highly aggressive’, At02 ‘pathotype II: moderate aggressive’, and Sba02 ‘pathotype I: least aggressive’), there is a difference in genotypes reaction to A. rabiei isolates but very important resistance was observed (>50% of accessions collection). All five C. judaicum accessions are resistant to A. rabiei isolates, two resistant accessions in the wild species C. echinospermum (ILWC0 and ILWC246) and three accessions in C. reticulatum (ILWC81, ILWC104 and ILWC247), C. cuneatum (ILWC37, ILWC40 and ILWC232) and C. bijugum (ILWC195, ILWC285 and ILWC286). Key words: Ascochyta rabiei, Cicer arietinum, Cicer sp., aggressiveness, resistance.
Highlights
Chickpea is an important food legume crop in the Central, West Asia and North Africaregion (CWANA), accounting for 29% of the total food legume production (Singh, 1990; Zohary and Hopf, 2000; Kerem et al., 2007)
The mean diseases scores and their standard deviations (SD) for all chickpea germplasm and wild relatives accessions tested in four separate trials are mentionned in the Tables 3, 4, Table 6
The screening of wild Cicer species accessions showed a different behavior to three pathotypes of A. rabiei
Summary
Chickpea is an important food legume crop in the Central, West Asia and North Africaregion (CWANA), accounting for 29% of the total food legume production (Singh, 1990; Zohary and Hopf, 2000; Kerem et al., 2007). It serves as a source of inexpensive high quality production in the diets of many people and provides a rich crop residue for animal feed (Singh et al, 1992). Winter sowing expands the vegetative growth period and improves the seed yield up to 2 tonnes/ha
