AbstractFoliar application of micronutrient is a rapid and promising strategy to enhance the concentration and bioavailability of micronutrients in wheat grain. To explore the effects of foliar application of micronutrients on the concentration and bioavailability of zinc and iron in grain in wheat cultivars and landraces, field experiments were carried out using 65 wheat cultivars and 28 landraces to assess the effects of foliar application of zinc (iron) on phytic acid concentrations, zinc (iron) concentrations and their molar ratios. The results indicated that mean grain zinc concentration of landraces (44.83 mg kg−1) was 11.13% greater than that of cultivars (40.34 mg kg−1) on average across seasons, while grain iron concentration did not differ significantly between landraces (41.00 mg kg−1) and cultivars (39.43 mg kg−1). Foliar zinc application significantly improved the concentration and bioavailability of zinc in grains in both cultivars and landraces, while landraces had almost two-fold more increase in grain zinc and also greater improvement in zinc bioavailability compared to cultivars. While foliar iron application did not significantly affect iron concentration and bioavailability in grains in either cultivars or landraces. Our study showed that, with foliar application of zinc but not iron, wheat landraces had better performance than cultivars in terms of the increases in both concentration and bioavailability of micronutrient in grains.

Pot Culture

Effects of nitrogen on uptake, accumulation and partitioning of zinc throughout the development of wheat were studied under pot-culture conditions. The results showed that under low zinc application (0.2 mg kg-1) the grain zinc content increased by 140% when nitrogen fertilizer increased from 50 mg kg-1 to 150 mg kg-1. Under high zinc application (5 mg kg-1) the grain zinc content increased by 61%. Increasing nitrogen application under low zinc fertilizer, the grain zinc mainly comes from the root zinc uptake. While increasing nitrogen application under high zinc fertilizer, the grain zinc mainly comes from the straw zinc remobilization.

Zinc Application

This study was carried out to elucidate the impacts of zinc (Zn) treatments on growth, development, quality and yield of commonly sown bread wheat cultivars under field conditions of Çukurova Region. Three different bread wheat cultivars (Adana-99, Ceyhan-99 and Pandas) were experimented in randomized complete blocks-split plots experimental design with 3 replications. Field experiments were performed by two different Zn application methods; via soil and via soil+foliage. In the both trials, 0, 5, 10, 20, 30, and 40 kg ha-1 pure Zn doses were applied to the soil. 0.4% ZnSO4.7H2O solution was used for foliar Zn applications. Current findings revealed that Zn treatments had significant effects on grain yield, grain Zn concentration, grain phosphorus (P) concentration and thousand grain weight of bread wheat cultivars, but significant effects were not observed on grain protein concentrations. Soil+foliar Zn treatments were more effective in improving grain Zn concentrations. It was concluded that 10- 20 kg ha-1 Zn treatment was quite effective on grain Zn concentrations.

Molecular Marker Analysis

Genetic biofortification is a strategy that uses plant breeding techniques to produce staple food crops with higher micronutrient levels and can be a feasible and costeffective means of delivering micronutrients to population that may have limited access to diverse diets. The present study reports the development of wheat with high grain protein, yellow pigment and high zinc content in addition to introgression of rust resistance genes to ensure biofortification as well as yield sustainability. A convergent cross for combining gene(s) for high protein, high yellow pigment, high zinc and rust resistance was performed. This included crossing BC1F2 introgression lines of cross PBW698/BF22//PBW698 carrying grain zinc QTL introgressed from Triticum monococcum with high protein line BWL3560 having Gpc-B1. A set of 192 F3 lines were evaluated for agronomic and quality traits. Molecular marker analysis of F3 progenies for Gpc-B1 gene (Xucw108) revealed 129 F3 lines to be homozygous positive. The progenies showed the range of 8.96-13.92% for grain protein content, 25.1-36.3mg/Kg for grain iron concentration, 34.0-54.0 mg/Kg for grain zinc concentration and 2.01-4.57ppm for grain yellow pigment content compared to 9.65%, 26.7 mg/Kg, 42.9 mg/Kg and 3.74ppm respectively in recipient line PBW698. Therefore, this population constituted a useful material for identifying the nutritionally enhanced lines.

The Stability

Background: Balanced nutrition is an essential part of human diet and rice being consumed by more than half of the world population, having rice cultivars biofortified for high Zinc levels in polished rice would be very important to combat issues of malnutrition. Zinc being a highly variable trait and influenced by environmental and soil conditions, a multi-location stability analysis was conducted to identify cultivars stable for high grain Zinc with consistency in yield performance. Methods: Present experiment was conducted to study the stability of 22 high zinc rice genotypes in five different locations of Eastern Uttar Pradesh in RCBD with three replications in all the locations and 12 different traits were included in the study. Eberhart and Russell model was used for evaluating the stability of the genotypes. Results: The results reported high significance for all the twelve characters studied. Mean sum of squares due to environment as well as linear component of environment were significant for all the characters suggesting presence of variation among the five environments tested. All the twenty-two genotypes showed significant differences for all the characters when tested against pooled error and pooled deviation. The genotype, IR15M1633 recorded highest mean grain Zinc content but have negative association with yield. Therefore, considering for a high grain Zinc genotype with consistent yield performance, the genotypes, DRR Dhan 48 and HURZ-3 showed good mean values for all the traits and was also stable for grain zinc, yield per hectare, 1000 grain weight, had shorter plant height and can be suggested for use as high yielding cultivars with high grain Zinc and could be further used in breeding programmes successfully.
