Abstract

Two lines of Aegilops squarrosa (G 3489 and G 1279) and Triticum cultivars Anza, Cocorit, Produra, Chinese Spring, Nugaines, and a synthetic hexaploid were screened for resistance to Meloidogyne chitwoodi. Reproduction of M. chitwoodi, expressed as eggs per gram root, was low (P 0.01) on G 3489 and the synthetic hexaploid. Reproduction on all other cultivars tested was high although differences (P 0.01) existed among them. Key words: Aegilops squarrosa, Columbia root-knot nematode, Meloidogyne chitwoodi, resistance, Triticum aestivum, wheat.
