dc.description.abstract | Ascochyta blight (Ascochyta rabiei Lab.) is an economically important fungal disease on chickpea in
Morocco, and in other parts of the world. Significant progress has been made in breeding chickpea for
Ascochyta blight resistance in Morocco, but the plant resistance is typically overcome by the evolution
of virulent pathotypes of the pathogen. In this study pathogenic variability among a population of A.
rabiei isolates, collected from four different chickpea growing regions in Morocco (Doukkala-Abda,
Chaouia, Gharb and Saiss), was assessed by screening over a set of chickpea differential genotypes. On
the basis of the pathogenicity test, the isolates were classified into three pathotypes groups. The most
aggressive pathotype (PIII) was present in the majority of surveyed regions, however the weak aggressive
pathotypes (PI and PII) were the most widespread. Genetic analysis with SSR fingerprinting of these
isolates distinguished high variability within and among identified pathotype groups of A. rabiei,
indicating low correlation between their virulence and the genetic pattern. The characterization of disease
reaction of 6 Moroccan varieties and 18 selected chickpea genotypes against isolates from these three
pathotypes groups revealed a high variability. None of them were resistant to PIII and only one variety
and one genotype were resistant to PII and PI together. Results of this study will be useful in breeding
for Ascochyta blight-resistant chickpea cultivars and development of efficient screening strategies in
Morocco. | en_US |
