Abstract
The effect of strawberry crinkle virus on the yield and quality of two strawberry cultivars, Madame Moutot and Jukunda, were studied over a 3-year period in a replicated field experiment.
In the cultivar Madame Moutot, the average yield of virus-infected strawberries in relation to healthy controls was 75% in the first year, 52% in the second, and diminished rapidly to 36% in the third year.
In Jukunda, the corresponding figures were 68, 59 and 39%. The chemical constitution of infected fruits was significantly altered in both cultivars.
Thus, in both cultivars, the dry matter content of infected fruits was about 17% lower than the controls.
Total sugar content was 12–18% lower, total acids about 14–15% higher, and pH value about 4–5% lower.
In both cultivars the differences in yield and chemical composition were statistically very significant.
