To optimize global food production, researchers are investigating the susceptibility of different wheat cultivars to the fungal pathogen Fusarium, which causes severe crop spoilage. A field trial monitored the performance of five cultivars grown under intensive agricultural conditions. The trial recorded the total number of plants cultivated and the number of those plants that developed severe Fusarium infections:
The susceptibility of a cultivar is determined by its infection rate (the percentage of grown plants that contract the infection).
