SUMMARY Ten ‘globe’ and two ‘long’ red beet cultivars were tested for susceptibility to Streptomyces scab in a field trial on a scab‐infested Black Fen peat soil. The long beet cultivars Red Perfection and Cheltenham Green Top had little scab and about 75 per cent of roots had none or only one small lesion (‘scab free’). Of the ‘globe’ beets, Avon Early and Elsoms No. 257 were most resistant with only 2 per cent of the surface area scabbed and 75 per cent of roots ‘scab free’, Little Ball and New Globe were most susceptible with 8 to 9 per cent of the surface affected and only 33 per cent of roots ‘scab free’. The widely grown Boltardy and Crimson Globe had about 7 per cent of the surface area scabbed and 45 per cent of roots ‘scab free’.
