Characterisation ofAscochyta rabieiisolates and evaluation of genotypic stability in chickpea

Ascochyta rabiei isolates were characterised for their variability using a set of host differentials following cloth chamber screening technique. Sixty chickpea genotypes were evaluated against the characterised 10 individual pathotypes separately to identify genotypes with stable resistance during 2007–2008. Twenty four genotypes showed resistance to all the pathotypes; whereas 18 genotypes were resistant to moderately resistant to these pathotypes. The above genotypes can be considered good sources of stable resistance and recommended as donors or for direct cultivation in north western plain zone of India.
