Figure 1. Comparison of Fruit images with R/B phenotype value. Fruit color ranges from dark to light brown color as R/B value increases. The maximum R/B value among 179 samples is 3.59, and the minimum value is 0.86. a:  Fruit images of 10 samples which the highest R/B value. b:   fruit images of 10 samples which the lowest R/B value.
