Physiological races of V. inaequalis.

Races	Pathological characteristics on apple cultivars
Race1	Non sporulating lesion on Dolgo, R 12740-7A (a Russian cultivar) and Geneva
Race 2	Sporulating lesions on Dolgo, Geneva and some progenies of R 12740-7A
Race 3	Sporulating lesions on Geneva, and non sporulating lesion on Dolgo, R 12740-7A
Race 4	Non sporulating lesion on Dolgo, Geneva and sporulating lesion on those progenies of R12740-7A on which race 2 isolates cannot sporulate
Race 5	Sporulating lesions on Vm R gene containing cultivars
Race 6	Sporulating lesions on Vf hybrids but cannot infect Malus floribunda 821 containing Vfh R gene
Race 7	Can infect cultivars having Vf and Vfh R gene but cannot infect Golden delicious which contains Vg gene
Race 8	Can infect Golden delicious, Royal gala, and cultivars containing Vh8 R gene
