Breeding for resistance to rhizomania in sugar beet: a review

Currently rhizomania is the most important disease in sugar beet worldwide, and attack can lead to serious yield losses. The disease is caused by beet necrotic yellow vein virus (BNYVV) that is transmitted by the soil-borne fungus Polymyxa betae. Breeding sugar beet cultivars with resistance to rhiz...

Description
Summary:Currently rhizomania is the most important disease in sugar beet worldwide, and attack can lead to serious yield losses. The disease is caused by beet necrotic yellow vein virus (BNYVV) that is transmitted by the soil-borne fungus Polymyxa betae. Breeding sugar beet cultivars with resistance to rhizomania is regarded as the most appropriate way to enable continued production of this crop in BNYVV-infested fields and also to slow the spread of the disease. Breeding for resistance started with selection by scoring disease symptoms in field experiments. The development of non-destructive greenhouse tests, with determination of the virus concentration in rootlets using ELISA, has greatly improved the efficiency of selection. In this paper the impact of scientific research on the progress in breeding cultivars with resistance to rhizomania is reviewed. This includes the distribution, composition, and pathogenicity of the virus, the sources of resistance to virus and vector, the genetics of virus resistance, progress with breeding methods, and the use of molecular markers and pathogen-derived resistance. The yields and quality characteristics of recently introduced resistant cultivars now equal those of the commercial susceptible cultivars.[PUBLICATION ABSTRACT]
