“…Highyielding germplasm lines with improved micronutrient levels were grouped together (Tabat and Abusabiba). Selection and crossing of genotypes from different clusters would help in bringing together genes favorable for yield and quality traits so as to breed tailormade varieties (Badigannavar, Girish, & Ganapathi, 2015;Shergo, Labuschagne, Shargie, & van Biljon, 2013).…”

In the last decades, deficiency of macro‐ and micronutrients was considered as a serious problem associated with the increase in the human population. To meet the increased demand for food consumption, the wild relative plant might serve as an important source of new genetic material for increasing macro‐ and micronutrients. To investigate this, the variations in protein content, in vitro protein digestibility, tannin content, phytic acid content, total polyphenol content, and total and bioavailability of minerals were studied in grains of ten wild sorghums and two released sorghum cultivars. The results showed significant differences ( p ≤ 0.05) in all quality tests among the genotypes. The highest percentage of total protein contents and in vitro protein digestibility were encountered in the grains of PQ‐434 (14.6%) and the released cultivar AG8 (49.8%), respectively, while the highest concentrations of total and bioavailable iron were found in the grains of Almahkara (3.17 mg/100 g) and Abusabiba (92.8 mg/100 g), respectively. The grains of wild sorghum genotype Adar Umbatikh grains were found to possess higher total zinc contents. The PCA identified only five components of eigenvalues greater than one and cumulatively accounted for 88% of the total variation. It could be concluded that Almahkara and PQ‐434 could be used as potential sources for iron and protein sorghum biofortification, respectively. Results from this study might be used in the development of new value‐added products from wild sorghum grains by‐products.

“…The magnitude of gene expression and trait associations provides the basis for selection of genotypes in planning future breeding programs. The genetic variation for seed phosphorus and yield traits in Indian sorghum landraces was studied by Badigannavara, Girish, and Ganapathi (). The variation in phytic acid content could be due to different strain types and environmental conditions of cultivation.…”

Phytic acid is considered as the major storage pool for phosphorus in the seeds. Present study was experimented on 60 chickpea genotypes for MIPS gene, antioxidant activity, mineral content and phytic acid content. PCR analysis successfully amplified 400 bp fragment of MIPS gene in chickpea. The average phytic acid content observed across all the genotypes was 59.27 mg/100 g. The mineral content assorted for Fe and Zn was 2.41–129.98 mg/100 g and 313.58–1,490.47 mg/100 g, respectively. Significant association of high phytic acid and its mole ratio to zinc was depicted. The relationship between phytic acid content and mineral bioavailability was strongest in Fe (r = 0.448**) followed by Zn (r = 0.959**). This suggest that phytic acid significantly reduce the mineral bioaccessibility. Cluster analysis revealed the distinctness among genotypes on the basis of phytic acid and antioxidant activity and grouped them into seven clusters. Cluster (a) contains low phytic acid genotypes while cluster (b) grouped most of the high phytic acid contenting genotypes. Practical applications Phytic acid chelates micronutrient which prevent their bioavailability. Objectives of plant breeding programs demand enhancement of micronutrient concentration, antioxidant levels with low levels of phytic acid. The present study identified chickpea genotype KWR‐108 with high Fe and Zn contents with average levels of phytic acid. This genotype show prospective food source for commercial applications and can be used as a parent for designing future breeding program.

“…For instance, phytic acid chelates positively charged minerals like Fe and Zn, forming insoluble complexes and causing decreased mineral absorption, in addition to forming complexes with protein, thus slowing the digestion rate and hampering their bio-availability ( 48 ). Several low phytic acid-containing landraces such as Malkhed-1 and Nalwar-2 and a variety Phule Maulee were reported ( 49 ). Due to these anti-nutrient interactions and the limited bio-availability of sorghum compared with other grains ( 50 ), harnessing the potential of nutrient-rich landraces and genotypes such as PSLRC-2, PSLRC-3, PSLRC-9, PYPS 2 and PYPS 13 by reducing the anti-nutritive factors should be an important goal especially in the arid and semi-arid regions of Asia and Sub-Saharan Africa, where malnutrition and nutritional deficiencies are prevalent in women and children.…”

Sorghum (Sorghum bicolor L. Moench) is the staple cereal and is the primary source of protein for millions of people in Asia and sub-Saharan Africa. Sorghum grain value has been increasing in tropical countries including India owing to its gluten-free nature, anti-oxidant properties and low glycemic index. However, the nutrient composition of modern cultivars is declining thus necessitating genetic biofortification of sorghum to combat malnutrition and improve nutritional balance in the human diet. Keeping this in view, efforts were made to utilize valuable alleles, associated with nutrient composition, that might have been left behind in the varietal development in sorghum. The study aimed to determine the genetic improvement for nine nutritional and quality parameters (crude protein, in vitro protein digestibility (IVPD), total iron (Fe), total zinc (Zn), bioavailable Fe (%), bioavailable Zn (%), total phenolics, tannins and antioxidant activity) in the grains of 19 sorghum genotypes (high yield, drought and grain mold tolerant) developed from 11 superior India’s landraces. After selection and advancement made from 2017 to 2022 through single seed descent method, the improvement in the nine nutritional and quality parameters was assessed. Significant variation was observed for all the nine parameters among the landraces and the genotypes. Sorghum genotypes PYPS 2 and PYPS 13 recorded the highest crude protein (13.21 and 12.80% respectively) and IVPD (18.68 and 19.56% respectively). Majority of the sorghum genotypes recorded high Fe (14.21–28.41 mg/100 g) and Zn (4.81–8.16 mg/100 g). High phenolics and antioxidant activity were recorded in sorghum genotypes PYPS 18 (85.65 mg/g gallic acid equivalents) and PYPS 19 (89.78%) respectively. Selections through SSD method revealed highest improvement in genotype PYPS 10 for crude protein (32.25%), total phenolics (18.48%) and antioxidant activity (15.43%). High improvements in genotypes PYPS 12 (23.50%), PYPS 3 (26.79%), PYPS 15 (21.18%) were recorded for total Fe, available Fe and high tannins, respectively. The study demonstrated that landraces could be effectively utilized as a potential, low-cost and eco-friendly approach in sorghum genetic biofortification to improved sorghum productivity and nutritional supply in semi-arid tropics.
