Fig. 3.
Scanning electron images of sporulating leaf spots of C. beticola on four genotypes of Beta vulgaris differing in CLS resistance. Leaf spots on partially resistant genotypes (Bv1 + Q, Bv4_r) were smaller and/or had a smaller centre with lower production of conidiophores than those formed on susceptible genotypes (Bv2-Q, Bv6_s)
