Description
Bacterial wilt of fodder grasses caused by Xanthomonas campestris pv. graminis was first described by Egli et al. (1975), and since then observed all over Europe and in New Zealand. The regular mowing of the crop offers ideal conditions for spreading of the pathogen. Several grass species are affected. The most severe yield losses occur in Lolium multiflorum, particularly in var. westerwoldicum. In extreme cases, all the plants can be killed during hot, dry summers. Gondran and Betin (1988) found up to 47 % of yield loss in the three cuts following inoculation of Italian rye-grass cultivars. Losses are less severe in Festuca pratensis, L. perenne, F. arundinacea, F. rubra and species of lower importance. Dactylis glomerata can be infected, usually without much damage. Important differences in susceptibility exist amongst cultivars of the same species and breeding for resistance is possible. This article discusses problems related to resistance breeding

Breeding for Resistance to Bacterial Wilt of Grasses (Xanthomonas campestris Pv. Graminis)
