Phenotyping system for cranberry cuticular wax. A Cranberries with low epicuticular wax (ECW) have a shiny, smooth appearance and B those with high ECW have a dull, white, powdery surface appearance. C Cranberry ECW phenotyping was conducted manually using a subjective visual rating system of 0–5 corresponding to the relative amount of ECW load on the surface of berries, where 0 denotes little wax and 5 denotes relatively high ECW. D Frequency distribution illustrates the variability in ECW rating within the QTL population (n = 68)
