Quantitative traits of seed pericarp color were used to evaluate the sugar beet (Beta vulgaris L.) seed quality. These traits were measured on 10 single cross hybrids along with the male parent produced in three locations, Ardebil, Firouzkooh and Karaj, Iran. The quantitative traits included 9 color traits based on which the traits L*(Lightness/Luminance), a*(Red/Green color), b*(Blue/Yellow), RGB (Red-Green-Blue) and HSV (Hue- Saturation-Value) were measured. Results showed significant differences among the hybrids for seed pericarp color. The hybrids were classified into four clusters. Cluster C-2 which had the least L*, b*, R, G as well as quantity of color value (V) and included the SC (231*SB37), SC (231*SB17) and SC (231*SB16) single crosses, contained high quality seeds. The quantitative color traits were significantly correlated with some seed germination traits. Sugar beet seed pericarp color traits were related to female parent not to male parent and displayed significant correlations with the ratio of embryo to seed pericarp weight. In conclusion, analysis of quantitative traits of sugar beet seed pericarp color can be used to determine the time of maturity, to group the cultivars and to rank the seed quality.
