RESULTS
Phenotypic data
In the Tamar stage, among other changes, date palm fruit color varies
from light brown to dark brown. For the genome-wide analysis study, we
used the intensity of Red, Green & blue color channels and the ratio of
Red/Blue ( R/B), Red/Green (R/G ), and Green/Blue (G/B) as phenotype.
Manual analysis of fruit images with the ratio of Red and Blue channel
intensity (R/B) showed that higher values of R/B are associated with
light brown and lower R/B values with dark brown (Figure 1). We,
therefore, focused our analysis on R/B color phenotype for the
genome-wide analysis of fruit color.
