Twenty varieties and advanced seedlings, reported tolerant to Verticillium wilt, were compared in field trials during spring and autumn on plots infested with V. dahliae and on comparable non-infested plots. Yield criteria were used to analyze the level of field resistance. Ona-2249 was the only variety tested which gave similar yields in both growing seasons and under both infested and non-infested soil conditions, as compared to those of Up-to-Date, the standard variety. © 1975, Springer.
