First Report of Chickpea Resistance to PEMV (Porter)

Significant losses in chickpea production have occurred due to the Pea Enation Mosaic Virus (PEMV) in the Palouse Region of the Pacific Northwest USA in 1990, 1996, and 2005 and can cause significant losses in other chickpea production areas throughout the world. None of the current chickpea cultivars used by growers in the Pacific Northwest have any resistance to PEMV.  Eight PI accessions from the desi-type chickpea germplasm were identified with high resistance to PEMV and one Kabuli-type had high tolerance to PEMV.  This was the first report of chickpea germplasm with resistance/tolerance to PEMV and the resistant germplasm is available to breeders to introgress resistance genes into advanced breeding lines and commercial cultivars to produce new varieties with resistance to PEMV.
