1980年，6个玉米杂交种分别接种了6株玉米G. zeae菌株，以确定杂交种之间是否发生了穗腐病和霉菌毒素积累的相互作用。在霉菌损伤方面观察到统计上显著的相互作用，但没有发生大的逆转。所有六种菌株都鉴定出同一种杂交品种具有最强的抗性。1981年，最初的六种杂交品种中的三种用三种新菌株进行了测试。没有观察到相互作用。这两个季节常见的杂交品种多年来一直保持着它们的相对排名。对玉米赤霉烯酮和呕吐毒素含量进行了两年的分析。毒素水平与霉菌损害率显著相关（r = 0.69 ~ r = 0.83）。当对霉菌水平进行协方差调整时，发现两年内杂交种的毒素积累量差异不显著。1980年仅对玉米赤霉烯酮观察到菌株效应和杂种×菌株效应。这些数据表明，一个菌株就足够了。
In 1980, six corn hybrids were inoculated with each of six strains of G. zeae in order to determine whether hybrid-strain interactions occur with respect to ear rot and mycotoxin accumulation. A statistically significant interaction was observed for mold damage, but no large-rank reversals occurred. All six strains identified the same hybrid as being the most resistant. In 1981, three of the original six hybrids were tested with three new strains. No interaction was observed. Hybrids common to the two seasons maintained their relative ranking over years. Analyses for zearalenone and vomitoxin content were performed for both years. Toxin level was significantly correlated with percent mold damage in both years (r = 0.69 to r = 0.83). When covariance adjustment for mold level was performed, hybrids were found not to differ significantly for toxin accumulation in either year. A strain and hybrid × strain effect was observed only for zearalenone in 1980. These data indicate that a single strain should be adeq...
