Description
Red clover (Trifolium pratense L.) is one of the most important species for forage production in Sweden. The use of red clover is however restricted by poor persistence among other things caused by attacks of fungal diseases like clover crown rot and root rot. Investigations have shown (Rufeldt, 1986) that root rot is distributed in almost every field where red clover is grown and is one of the main reasons for the poor persistence. In the same investigations Fusarium roseum, Phoma medicaginis and Cylindrocarpon sp. are pointed out as the most important fungi in the root rot complex. One way to control the root rot disease would be to produce resistant cultivars. This paper describes a laboratory method for selection for root rot resistance and the results obtained when this method was applied to two populations of early red clover.
