Phenotypic data
Photographs were taken of 5 to 11 Tamar stage fruit from each cultivar along with a color-checker card and a ruler as a size standard (Supplementary Figure 1). Pictures were taken on a white background with a digital camera. For more detailed description please refer to Stephan et al (Stephan et al., 2018). Out of 199 samples, only 179 fruit samples were available for phenotypic data and used for the association study. We measured fruit color by recording the intensity of the Red (R), Green (G) & Blue (B) color channels (RGB) in each photograph for each fruit using MIPAR Software (Sosa et al.,2014). The color channel intensity of multiple fruit was calculated separately and then averaged for each cultivar. The average intensity of each color channel (R, G &B) and the ratio of the color channel such as R/G, R/B & G/B were used as phenotype data for the association mapping study.
