Table 3 Mean, range of variation, standard deviation (SD), coefficient of variation (CV) and heritability (h2 B) in the whole collection and in the durum sub-population evaluated for yellow index (b*) and yellow pigment content (μg/g) in six and two environments, respectively

From: The carotenoid biosynthetic and catabolic genes in wheat and their association with yellow pigments
