  1. For each trait at least one common letter indicates no significant difference according to the Duncan test (α = 0.05).
  2. L* represents the brightness; a* is an index of red colour (i.e. higher the value, stronger the red colour); b* is an index of yellow colour (i.e. higher the value, more intense the yellow colour).
