Resistance to rusts (Uromyces pisi and U. viciae-fabae) in pea

Pea is the second most important food legume crop in the world. Rust is a pea disease widely distributed, particularly in regions with warm, humid weather. Pea rust can be incited by Uromyces viciae-fabae and by U. pisi. U. viciae-fabae prevails in tropical and subtropical regions such as India and China, while U. pisi prevails in temperate regions. Chemical control of rust is possible, but the use of host plant resistance is the most desired means of rust control. In this paper we revise and discuss the occurrence and incidence of both pathogens on peas, the availability of resistance sources and the present state of the art in pea breeding against this disease.

Uromyces pisi-sativi. [Descriptions of Fungi and Bacteria].

A description is provided for Uromyces pisi-sativi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pycnia and aecia on Euphorbia, uredia and telia on Lathyrus, Orobus, Pisum and Vicia. DISEASE: Rust on pea, vetches and broad bean. GEOGRAPHICAL DISTRIBUTION: Africa (Canary Islands, Ethiopia, Libya, Morocco); Asia (China, India,? Iran, Pakistan, Turkey, U.S.S.R.); Europe (Austria, Belgium, Bulgaria, Corsica, Cyprus, Czechoslovakia, Denmark, Finland, France, Germany, Great Britain, Greece, Hungary, Italy, Malta, Netherlands, Norway, Poland, Portugal, Romania, Sicily, Spain, Sweden, Switzerland, U.S.S.R., Yugoslavia); South America (Argentina, Chile) (CMI Map 404 and Herb. IMI). TRANSMISSION: Pea rust has been recorded at a distance of 25 km from the nearest source of infected Euphorbia cyparissias in Norway by Jorstad (1948), who considered wind-borne spores from other extraneous sources unlikely. Wild species of Lathyrus tuberosus serve as source of infection to vetchling in U.S.S.R. (39: 717).
