Table 2.
Effects of genotype, environment and their interaction (G × E) expressed as % of the total sum of squares from ANOVA analysis.

TW, test weight; TKW, thousand kernel weight; GPRO, grain protein content; FeC, iron content; ZnC, zinc content; Phy:Fe, phytic acid:iron molar ratio; Phy:Zn, phytic acid:zinc molar ratio.
All values were highly significant (p < 0.001), except +significant (p < 0.05); ++ (p < 0.01) and ‘□’ not significant.
