RESPONSE OF FORAGE VETCHES AND FORAGE PEAS TO ROOT-KNOT NEMATODE (MELOIDOGYNE ARTIELLIA) AND CYST NEMATODE (HETERODERA CICERI)

Abstract

One hundred genotypes (lines) of forage peas (Pisum sativum L.) and eighty-one of vetches (Vicia spp.) were examined for their response to cyst nematode (Heterodera ciceri) and root-knot nematode (Meloidogyne artiellia) in 1985/86 and 1986/87 seasons in a heavily infested field with both nematodes at ICARDA's research station in Northern-Syria. Forage peas genotypes were severely attacked by H. ciceri and vetches were severely attacked by M. artiellia. Only six genotypes of common vetch were attacked by both nematodes. Genotypes possessing resistance or tolerance under field conditions were tested in the glasshouse using artificial infection. Glasshouse tests indicated that woolly-pod vetch (Vicia villosa spp. dasycarpa sel. 683) was highly resistant to root-knot nematode, repeating its performance under field conditions. Field and glasshouse screening did not yield highly resistant common vetch genotypes to M. artiellia or highly resistant forage peas genotypes to H. ciceri, but some genotypes were tolerant.
