Abstract
Abstract Seven cultivars of gladiolus were evaluated for survival in mixed and separate plots exposed to Fusarium oxysporum over a period of 6 years. In mixed plantings the most resistant cultivars became the dominant survivors within 5 years. Cultivars planted separately (A) showed highly significant differences for wt of corms and cormels, number of cormels, and the number of flower spikes produced each year. Survival and production of these cultivars under field conditions were correlated with resistance to Fusarium oxysporum. Mixed plots (B) showed a highly significant shift in flower spike production toward resistant cultivars.
