Objective

To obtain new chickpea germplasm with Ascochyta resistance from diverse geographical regions. To develop integrated chickpea linkage map and consolidate meta-QRL (Quantitative Resistance Loci) for Ascochyta resistance. To identify genes related to Cicer - Ascochyta rabiei recognition and general defense pathways.

Outcome

This research showed that resistance to A. rabiei is controlled both by genes for recognition of specific pathogen isolates and genes involved in common defense pathways. Consequently, it is suggested that resistance breeding is best achieved by combining both types of resistance in new chickpea varieties.
