Abstract: | Sixty-six spring and winter common wheat genotypes from Central Asian breeding programs were evaluated for grain concentrations
of iron (Fe) and zinc (Zn). Iron showed large variation among genotypes, ranging from 25 mg kg−1 to 56 mg kg−1 (mean 38 mg kg−1). Similarly, Zn concentration varied among genotypes, ranging between 20 mg kg−1 and 39 mg kg−1 (mean 28 mg kg−1). Spring wheat cultivars possessed higher Fe-grain concentrations than winter wheats. By contrast, winter wheats showed higher
Zn-grain concentrations than spring genotypes. Within spring wheat, a strongly significant positive correlation was found
between Fe and Zn. Grain protein content was also significantly (P < 0.001) correlated with grain Zn and Fe content. There were strong significantly negative correlations between Fe and plant
height, and Fe and glutenin content. Similar correlation coefficients were found for Zn. In winter wheat, significant positive
correlations were found between Fe and Zn, and between Zn and sulfur (S). Manganese (Mn) and phosphorus (P) were negatively
correlated with both Fe and Zn. The additive main effects and multiplicative interactions (AMMI) analysis of genotype × environment
interactions for grain Fe and Zn concentrations showed that genotype effects largely controlled Fe concentration, whereas
Zn concentration was almost totally dependent on location effects. Spring wheat genotypes Lutescens 574, and Eritrospermum
78; and winter wheat genotypes Navruz, NA160/HEINEVII/BUC/3/F59.71//GHK, Tacika, DUCULA//VEE/MYNA, and JUP/4/CLLF/3/II14.53/ODIN//CI13431/WA00477,
are promising materials for increasing Fe and Zn concentrations in the grain, as well as enhancing the concentration of promoters
of Zn bioavailability, such as S-containing amino acids. |
