摘要

In Pakistan, evaluation of the nutritional quality of wheat is essential to address dietary gaps and deficiencies. Twelve Pakistani wheat cultivars were examined to explore the correlations between key nutritional factors, including protein, amino acids, moisture, ash, starch, and fiber content. The correlation study identified that six cultivars with higher protein concentrations generally had a lower level of starch. In contrast, seven cultivars exhibited an inverse relationship between protein concentration and fiber. Although the fiber content varied independently, a positive correlation between fiber and starch concentrations was observed in two cultivars. Variations in ash content did not align with changes in other biochemical traits. Additionally, amino acid analysis revealed the highest concentrations in ‘Narc-11’ and ‘TD-01’, with lysine absent in all cultivars, indicating a critical gap in the essential amino acids. SDS-PAGE protein profiling showed significant differences in glutenin and gliadin fractions, with ‘Nawab’ and ‘TD-01’ exhibiting notable polymorphism and greater gluten protein diversity. The correlation analysis concluded that wheat cultivars with richer amino acid profiles, such as ‘TD-01’ and ‘Narc-11’, had higher protein content combined with more diverse gluten proteins and moisture content. This analysis identified the potential of five wheat cultivars (‘Narc-11’, ‘TD-01’, ‘Borlaug-16’, ‘Ujala-16’, and ‘FSD-2008’) as promising wheat cultivars with better nutritional profiles.
