Cereals and pulses are consumed as a staple food in low-income countries for the fulfillment of daily dietary requirements and as a source of micronutrients. However, they are failing to offer balanced nutrition due to deficiencies of some essential compounds, macronutrients, and micronutrients, i.e., cereals are deficient in iron, zinc, some essential amino acids, and quality proteins. Meanwhile, the pulses are rich in anti-nutrient compounds that restrict the bioavailability of micronutrients. As a result, the population is suffering from malnutrition and resultantly different diseases, i.e., anemia, beriberi, pellagra, night blindness, rickets, and scurvy are common in the society. These facts highlight the need for the biofortification of cereals and pulses for the provision of balanced diets to masses and reduction of malnutrition. Biofortification of crops may be achieved through conventional approaches or new breeding techniques (NBTs). Conventional approaches for biofortification cover mineral fertilization through foliar or soil application, microbe-mediated enhanced uptake of nutrients, and conventional crossing of plants to obtain the desired combination of genes for balanced nutrient uptake and bioavailability. Whereas, NBTs rely on gene silencing, gene editing, overexpression, and gene transfer from other species for the acquisition of balanced nutritional profiles in mutant plants. Thus, we have highlighted the significance of conventional and NBTs for the biofortification of cereals and pulses. Current and future perspectives and opportunities are also discussed. Further, the regulatory aspects of newly developed biofortified transgenic and/or non-transgenic crop varieties via NBTs are also presented.

“…To meet this task, high-yielding potential genotypes are needed. Several approaches have been employed for developing new genotypes with superior yielding potential and abiotic stress tolerance, such as population development, ideotype breeding, heterosis, wide crossing, genetic engineering and molecular breeding [3][4][5]. Rice is considered the greatest common and essential field crop in Egypt for numerous reasons as a (i) essential food after wheat for the Egyptian population, (ii) second exporting crop after cotton and (iii) soil reclamation crop for developing the production of the salty soil crops in which all farmers could increase money during its growing season.…”

Rice breeders are encouraged to classify potential F1-hybrids without crossing all viable mixtures by testing depending on genetic distance due to lack of labor and time in yield trials. The goals of this research were to establish heterosis and investigate the relationship between genomic distance and agronomic attributes under drought. Half-diallel mating design, 28 F1′s and 8 parents were evaluated under drought and genotyped using 11 microsatellite markers. In total, 39 alleles were detected. Results indicated that the greatest heterotic effects for grain yield were observed in Sakha 103 × Sakha 104 and GZ7576-10-3-2-1 × Giza 179, which gave 29.32–22.57% heterosis, respectively. Heterosis for grain yield in these crosses occurred as a rise in panicle weight, filled grains per panicle, low sterility and 100-grain weight. Correlations of marker-based genetic distance with mid-parent heterosis were positively and significantly correlated with sterility percentage (r = 0.390 *, p < 0.05). However, better-parent heterosis was positively and significantly correlated with sterility percentage (r = 0.352 *, p < 0.05) and grain yield per plant (r = 0.345 *, p < 0.05). Associations indicate that high grain yield and low sterility of rice crosses can be expected from microsatellite marker-defined distances of parents. This study indicated that genetic distance is very effective for heterosis prediction in breeding programs.

Kazakh Research Institute of Agriculture and Plant Growing developed bread wheat lines through wide crosses with Aegilops cylindrica Host, Ae. triaristata Willd., Triticum timopheevii (Zhuk.) Zhuk., T. militinae Zhuk. & Migush., T. kiharae Dorof. & Migush., and T. dicoccum (Schrank) Schübl. The best lines went through a multilocational evaluation process and were included in the Facultative and Winter Wheat Observation Nursery and submitted to the USDA for registration. We identified nine superior lines for potential use in research and breeding. The registered winter wheat lines combine the following agronomic traits: ‘Bezostaya‐1’*2/Ae. cylyndrica (KAZ1718, Reg. no. GP‐1056, PI 690701) with resistance to stripe rust, common bunt, and powdery mildew, thicker roots, and long fertile spike; Bezostaya‐1/T. militinae‐6 (KAZ1721‐6, Reg. no. GP‐1057, PI 690702) with resistance to stripe rust and common bunt and superior grain quality; Bezostaya‐1/T. militinae‐4 (KAZ1721‐4, Reg. no. GP‐1058, PI 690703) with resistance to stripe rust and common bunt, longer roots, large grain, high yield, and superior grain quality; and ‘Zhetysu’/T. militinae (KAZ1671, Reg. no. GP‐1059, PI 690704) with resistance to powdery mildew and longer roots. Spring wheat lines combine the following characteristics: ‘Kazakhstanskaya‐25’/T. timopheevii‐1 (KAZ43, Reg. no. GP‐1051, PI 690709) is resistant to stripe rust, is moderately resistant to common bunt, and has longer roots and high grain yield; 6625/T. timopheevii‐2 (KAZ41, Reg. no. GP‐1055, PI 690707) and 6631/T. timopheevii (KAZ44, Reg. no. GP‐1052, PI 690710) are resistant to all rusts and have high grain yield; 6631/T. militinae (KAZ45, Reg. no. GP‐1053, PI 690711) is resistant to leaf and stem rust and has high protein content; and ‘Kazakhstansakaya‐10’/T. dicoccum (KAZ42, Reg. no. GP‐1054, PI 690708) is resistant to leaf and stem rust and common bunt, had the highest grain yield, and has superior bread‐making quality. All germplasm represent new genetic diversity for use in breeding.
