Matching 1 point Consider if you were designing an experiment to identify potential sources of resistance to a fungal disease in barley landraces, using a natural inoculation in disease-prone environment and visual scoring lesions on the leaf. Match each experimental control to the "unfavored hypothesis" that could be excluded using that control. A fungicide treatment Well-adapted moderately-resistant commercial variety A known highly-susceptible variety A known highly-resistant variety Multiple Choice 1 point Hypothesis: The natural disease severity was too weak for effective screening Hypothesis: The observed lesions were not due to the fungal disease, but something else Hypothesis: The natural disease severity was too severe for effective screening Hypothesis: The planting failed to establish due to reasons unrelated to the fungal disease
