Summary

Southern Anthracnose, a fungal disease of red clover (Trifolium pratense L.) caused by Colletotrichum trifolii, seems to gain more importance in agriculture in Germany. This investigation should examine whether there is a simple possibility to increase the resistance in cultivars or breeding material through recurrent selection. Six red clover cultivars listed in Germany were used for this study. The survival rate after one and two cycles of recurrent selection was increased by 17 and 26 percentage points compared to the parental population. The advance in resistance generally was higher in populations with lower original resistance.
