u H = healthy pepper plants (control); S = CMV-S vaccinated; S/D = vaccinated plants challenge inoculated with CMV-D; D = healthy plants challenged
with CMV-D; S/16 = vaccinated plants challenge inoculated with CMV-16; and 16 = healthy plants challenged with CMV-16. The letter “A” after a
treatment means the infection was transmitted via aphids.
v Percent disease intensity was calculated using the formula 100(∑sn/SN), where s is the disease index score (disease was rated on a scale of 0 to 5, where
0 = no symptoms and 5 = severe symptoms), S is the highest s grade, n is number of plants with the same s, and N is total number of test plants indexed. w Percent disease prevention was calculated using the formula 100([C – V]/C), where C = disease intensity of plants inoculated only with CMV-D or CMV-
16 and V = disease intensity of vaccinated plants challenged with CMV-D or CMV-16. … = not applicable. x Average yield in kg/plant. Numbers in parentheses = ± standard deviation; means with the same letter are not significantly different at probability level P
= 0.05 according to Student’s t test. y Yield is the ratio of the average fruit yield from treated plants to the average fruit yield from healthy plants, expressed as a percentage. z TSS = total soluble solids as measured on refractometer. Numbers in parenthes
