“…Thus, there is a vast potential for genetically improving vegetable amaranths, harnessing their heterogeneity. Studies demonstrated substantial variability among A. hybridus and its sister species, reflected in both agronomic and qualitative traits [36][37][38][39][40][41]. All the traits examined in this study showed a remarkable variation in all the cultivars and significantly influenced leaf and seed yield.…”

To mitigate food insecurity and the low economic status of amaranth farmers in south-west Nigeria, it is imperative to evaluate the predominant commercial A. hybridus cultivars using key yield and nutrient components to identify promising lines with optimum yield and nutritional quality. The current study evaluated five cultivars of Amaranthus hybridus in south-west Nigeria farms using key morphological, biochemical, and seed-proximate component parameters. The results revealed significant differences in the cultivars’ growth and yield indices. The number of leaves ranged from 16.40 to 29.48 (x- = 22.10) with plant height (x- = 50.28 cm), while other leaf metrics varied at maturity. Days to 50% flowering ranged from 49 to 90 days. Seed proximate composition also varied significantly. Carbohydrate content ranged from 65.01–76.28%, protein content 6.57–12.42%, ash content 2.73–3.59%, total polyphenols 23.36–29.64 mg/100 g GAE, and total antioxidants 31.6–181.59 mg/100 g AAE. The Pearson correlation matrix and path analysis showed significant relationships among the yield components. The phenotypic variance of the yield components mainly stemmed from environmental factors, indicating their crucial role in the traits’ expression. Careful evaluation of the cultivars revealed that AM-1 and AM-3 had the best growth and yield attributes. Additionally, the two cultivars showed a significant degree of relatedness, suggesting a common ancestor. They have the potential to increase productivity, farmers’ profitability, and consumers’ nutrient gain compared to other cultivars. They are recommended for cultivation and can be further crossed in breeding programs to develop superior lines.

“…Genetic similarities were also important for the effective use of available germplasm by using phenotypic and molecular markers. Amaranth accessions were assessed for variations using random amplified polymorphic DNA (RAPD) primers ( 24 ) for getting information on genetic diversity for reliable gene recombination. For carrying out a successful hybrid program, analysis of phenotypic diversity and traits is very valuable.…”

“…These crops can be grown in most countries' environmental conditions and are easily available plant sources of micronutrients to alleviate micronutrient malnutrition ( 21 ). There is a need for their genetic improvement and to explore the breeding behavior of these crops, possibilities to create variations in population, and the use of molecular markers to study diversity in amaranth and quinoa ( 22 – 24 ) ( Table 3 ). We have reviewed genetic mapping studies and DNA barcoding to understand the gene sequence of these crops ( Table 3 ).…”

Nowadays, the human population is more concerned about their diet and very specific in choosing their food sources to ensure a healthy lifestyle and avoid diseases. So people are shifting to more smart nutritious food choices other than regular cereals and staple foods they have been eating for a long time. Pseudocereals, especially, amaranth and quinoa, are important alternatives to traditional cereals due to comparatively higher nutrition, essential minerals, amino acids, and zero gluten. Both Amaranchaceae crops are low-input demanding and hardy plants tolerant to stress, drought, and salinity conditions. Thus, these crops may benefit developing countries that follow subsistence agriculture and have limited farming resources. However, these are underutilized orphan crops, and the efforts to improve them by reducing their saponin content remain ignored for a long time. Furthermore, these crops have very rich variability, but the progress of their genetic gain for getting high-yielding genotypes is slow. Realizing problems in traditional cereals and opting for crop diversification to tackle climate change, research should be focused on the genetic improvement for low saponin, nutritionally rich, tolerant to biotic and abiotic stresses, location-specific photoperiod, and high yielding varietal development of amaranth and quinoa to expand their commercial cultivation. The latest technologies that can accelerate the breeding to improve yield and quality in these crops are much behind and slower than the already established major crops of the world. We could learn from past mistakes and utilize the latest trends such as CRISPR/Cas, TILLING, and RNA interference (RNAi) technology to improve these pseudocereals genetically. Hence, the study reviewed important nutrition quality traits, morphological descriptors, their breeding behavior, available genetic resources, and breeding approaches for these crops to shed light on future breeding strategies to develop superior genotypes.
