Abstract
Eighty radish cultivars from the USA and Europe were evaluated in 2 field trials for resistance to radish scab caused by S. scabies. White elongate (icicle) cultivars showed consistently less scab than red globe cultivars. A European cultivar, Sar Katra, was the only red globe cultivar exhibiting significantly greater tolerance to scab than an American standard cultivar, Scarlet Knight. Horticultural characteristics and lack of resistance to Fusarium yellows, however, make it unsuitable for use in this country.
