“…The biomass and biogas potential of amaranth was investigated in several studies [6,18,20,[30][31][32][33][34]. Comparative studies evaluated whether amaranths are competitive with maize as a bioenergy crop and revealed that maize is superior to amaranth due to its high performance in both dry matter yield and content.…”

Amaranth (Amaranthus spp.) is a promising biomass crop for silage and biogas production. Under long-day conditions, it exhibits prolonged vegetative growth. To evaluate the breeding potential of amaranth for biomass production, we characterized phenotypic variation in biomass yield components, quantitative genetic parameters, and the relationships between traits. We conducted field trials of 10 biomass-type genotypes exhibiting a ‘giant’ growth habit derived from spontaneous hybridization between genetically diverse parents, and used the variety “Bärnkrafft” as check. We observed two contrasting growth patterns: Bärnkrafft is a variety for grain production and was characterized by a short vegetative growth followed by a long seed ripening. In contrast, the biomass genotypes displayed a long vegetative growth followed by a short seed ripening. We observed strong correlations between dry matter content and stem diameter (r =−0.78, p < 0.01) and between plant height and biomass score (r = 0.95, p < 0.001). High values for broad-sense heritability of stem diameter (H2 = 0.88) and plant height (H2 = 0.92) suggest that the dry matter content and yield can be improved by indirect phenotypic selection. We hypothesize that selection for dry matter content and yield implies a trade-off between earliness and photoperiod sensitivity. Hence, dry matter content should be improved first by recurrent selection, which can be then combined with short-day genes to improve dry matter yield. Overall, this work provides an avenue to the breeding of biomass amaranth.

“…The biofuel production from amaranth also has the advantages due to high and relatively stable harvests compared to most of the other bioenergy crops, and in small demands for intensification factors, resulting in low production costs. But the success depends on the choice of appropriate species, genotypes having higher biomass and higher cell wall polymer contents [10,19,24]. The third table displays previous research on different bioenergy crops and their percentages of cell wall polymers.…”

Finding the nutritional value in soybeans is essential for keeping commodities at a low price while remaining conscious about people's health. This experiment brings into question whether it would be beneficial to consume soybeans more often and focus on the nutritional aspects of them, as well as the bioenergy benefits it provides. Therefore, the amounts of nutritional elements such as lipids, fatty acids, polyphenols, antioxidants, and soluble fibers tested within different varieties of soybeans. The highest phenolic content was in AS GROW 4754, followed by AS GROW 4632. The antioxidant capacity ranged from 2.35 3.44 µg/g of TEAC per 100g dry sample. The antioxidant activity follows as: AS GROW 4632> AS GROW 4754> AS GROW 4835. AS GROW 14632. AS GROWAG 4934. The Protein content ranges from 34.1 to 44.9 (%). The highest total protein was in AS GROW AG 4934, followed by AS GROW 4632, AS GROW 4754, AS GROW 4835 and AS GROW 14632. The lipid content ranges from 20.8 to 30.8 (%). The highest was in AG GROW 4835, and the lowest was in AS GROW 4632. Eight different fatty acids were found in the soybean. The Linoleic acid was found the predominant fatty acid 54%0 followed by Oleic acid (21%) and Palmitic acid (11%). The Behenic and Eicosenic acids found as trace amounts in soybean. Therefore, consumption of soybeans is beneficial but should also be incorporated within an overall healthy lifestyle. The difference in biomass and cell-wall components of five Arkansas grown soybean varieties examined to find out accessions that exhibited quality traits suitable for a potential bioenergy/biofuel crop. The Hemi-cellulose (HCE), cellulose (CE) and ASH contents ranged 14-30 %, 8-18 % and 1-3 % of the DM, respectively. The results showed that the NDF% ranged from 28 to 47, and ADF% ranged from 22-32. The extensive range of distinction in biomass and cell wall components point out that soybean has great potential for use as bioenergy/biofuel crops. The hypothesis was correct according to the results of the experiment, where several varieties showed high contents within all sources of nutritional value. The high amounts of cell-wall components between its species and in comparison to other bioenergy crops as well. The extensive range of distinction in biomass and cell wall components point out that soybean has great potential for use for multiple uses such as human food and nutrition, oil, energy, and biofuel potentials.

“…Under the long-day conditions of temperate Central Europe, photoperiod-sensitive amaranth genotypes delay flowering and display elongated vegetative growth. This observation prompted the evaluation of the biomass potential of amaranth in the context of biogas production, which revealed a promising performance and a potential for future improvement [16,[20][21][22][23][24][25]. In addition, amaranth can be used as a silage crop in both tropical and temperate regions, for which a high biomass is advantageous [14].…”

Grain amaranths (Amaranthus spp.) are ancient crops from the Americas that are consumed as pseudo-cereals and vegetables. Two grain amaranths, A. cruentus and A. hypochondriacus, originated in Central America, and A. caudatus in South America. Flowering time variation plays a central role in their uses as seed, vegetable and biomass crops. We characterized phenotypic variation for plant height, flowering time and seed setting among 253 genebank accessions including three grain and two wild ancestor species (A. hybridus and A. quitensis) in the temperate climatic and long-day conditions of Germany. Among grain amaranths, A. cruentus flowered early and 88% accessions set seed. A. hypochondriacus accessions were mildly or highly photoperiod-sensitive with a lower proportion of seed setting (31%). A. caudatus accessions were mildly photoperiod-sensitive and failed seed production. Photoperiod-insensitive accessions set seed regardless of their origin, and mildly photoperiod-sensitive accessions set seed if they originated from regions with higher temperatures. Overall, Central American accessions of both wild and domesticated amaranths showed large variation in flowering time and photoperiod sensitivity, whereas variation among South American wild and domesticated amaranths was limited to mild photoperiod sensitivity. This observation is consistent with a model of independent domestication in Central and South America, and suggests a potential Central American origin of A. hybridus followed by migration to and selection against high photoperiod sensitivity in South America. Our results provide useful information for the design of breeding programs for different uses, and provide insights into grain amaranth domestication by considering flowering time as an adaptive trait.
