Abstract
Downy mildew (Peronospora viciae (Berk) de Bary) is an important disease of vetches (Vicia spp.) in the Mediterranean Region. Narbon and common vetch germplasm accessions originating from different countries, and advanced breeding narbon vetch genotypes, were evaluated for reaction to downy mildew for two seasons under field conditions. In narbon vetch, there were resistant sources from both germplasm accessions and advanced genotypes. From the germplasm accessions, 25 accessions were resistant while from the advanced breeding genotypes, 10 had resistance, with 2–3 ratings. In common vetch, many accessions were highly resistant to downy mildew. These were widely distributed in different countries, mainly Turkey, Italy, Syria and Iran. In general, common vetch had higher sources of resistance than the narbon vetch accessions. These new sources of resistance to downy mildew will be incorporated into the forage legume improvement project in a continuous effort to identify cultivars suitable for replacing fallow in the cereal-based cropping systems.
