Genotypic and Environmental Variations in Kernel Color Indices in the Main Almond (Prunus dulcis (Mill.) D.A. Webb) Cultivars Grown in North-Eastern Morocco

Table 3

Coefficients of correlation among the studied traits: brightness index (L^∗), redness index (a^∗), yellowness index (b^∗), chroma (C^∗), hue angle (H^∗), and metric saturation (S^∗) of five almond cultivars grown in different sites of northern Morocco (Aknoul, Bni Hadifa, Tahar Souk, Rislane, and Sidi Bouhria) during three growing seasons (2016−2018). , , and indicate significance at 0.05, 0.01, and 0.001 levels of probability, respectively.
