“…Recently, various breeding achievements have been made that are related to the cold tolerance and early maturity of sorghum. New sorghum varieties together with agricultural alterations due to climate change, such as warming and longer growing seasons, facilitate the cultivation of sorghum as feed for livestock or for bioenergy applications (Kanbar et al, 2020; Schaffasz et al, 2019; Windpassinger, 2016). Furthermore, including other (possibly new) crop species and cultivars into crop rotations promotes diversification and enhances the sustainability of crop management (Hufnagel et al, 2020; Strauß et al, 2019).…”

Sorghum is currently being introduced in the temperate regions of Europe. It is characterized by good digestibility and high biomass yields, which make it a useful crop for anaerobic digestion. In this study, six commercial sorghum varieties comprising four different cultivars of Sorghum bicolor L. Moench and two interspecific sorghum hybrids (Sorghum sudanense L. × S. bicolor L. Moench) were harvested on two different dates during the years 2016 and 2017 at two diverse soil‐climate sites in Germany. The fresh harvested material and silages were analyzed to examine the ensilability of the different varieties with contrasting maturity characteristics. Subsequently, methane production experiments were performed to determine the specific methane yield (SMY) of the samples. The sorghum fresh matter (FM) varied among the sorghum types, including the parameters total solids (TS; 22.69%–46.93%FM), water‐soluble carbohydrates (2.68%–11.38%TS), and nitrates (0%–0.35%TS). The excellent ensiling ability of all the sorghum types analyzed was confirmed by evaluating the fermentation profile (pH range of 3.7–4.6; dominant presence of lactic acid [LA]; acetic acid [AA] in the range of 0.70%–2.38%TS; insignificant amount of butyric acid). The SMY ranged between 231.25 and 321.31 Ln kg−1 VS and tended to decrease with the increasing harvest time and maturity. LA and AA were positively correlated with the SMY, while the neutral detergent fiber content was negatively correlated with it. The SMY—a key parameter reflecting the crop biomass quality for biogas production—was slightly higher for S. bicolor than for the sorghum hybrids. However, the results of this study confirmed that if the final purpose is biomethanation, the ensilability of different sorghum types imposes no restriction. Furthermore, different sorghum types offer a wide harvest window, which can be useful for cropping schemes, ensiling, and methane production.

“…Although with morphological characters, the measurement of genetic diversity is much easier, however, these traits are highly affected by the environment (Tuinstra et al ., 1996; Van Beuningen and Busch, 1997; Abdi et al ., 2002). Previous researches have reported diversity assessment in sorghum using Random Amplified Polymorphism DNA (Agrama and Tuinstra, 2003; Kanbar et al ., 2019), Restricted Fragment Length Polymorphism (Deu et al ., 1994; Smith et al ., 2000), Simple Sequence Repeat (Smith et al ., 2000; Agrama and Tuinstra, 2003; Casa et al ., 2005; Deu et al ., 2006; Wang et al ., 2006) and Single Nucleotide Polymorphism (Murray et al ., 2009; Hu et al ., 2019)…”

Therefore additional research needs to be done on Nigerians sorghum genetic diversity for conservation and sustainable utilization.…”

Sorghum (Sorghum bicolor (L.) Moench) is an important resource to the national economy and it is essential to assess the genetic diversity in existing sorghum germplasm for better conservation, utilization and crop improvement. The aim of this study was to evaluate the level of genetic diversity within and among sorghum germplasms collected from diverse institutes in Nigeria and Mali using Single Nucleotide Polymorphic markers. Genetic diversity among the germplasm was low with an average polymorphism information content value of 0.24. Analysis of Molecular Variation revealed 6% variation among germplasm and 94% within germplasms. Dendrogram revealed three groups of clustering which indicate variations within the germplasms. Private alleles identified in the sorghum accessions from National Center for Genetic Resources and Biotechnology, Ibadan, Nigeria and International Crop Research Institute for the Semi-Arid Tropics, Kano, Nigeria shows their prospect for sorghum improvement and discovery of new agronomic traits. The presence of private alleles and genetic variation within the germplasms indicates that the accessions are valuable resources for future breeding programs.

“…It is mandatory, therefore, to comprehend how plants respond to P i starvation during the vegetative growth stage, and to design strategies to breed varieties with better P i uptake and use efficiency. For the current study, we took advantage of the morpho-physiological and molecular differences between a sweet (Della) and a grain (Razinieh) variety of sorghum [26][27][28][29], in order to understand how different sorghum types respond to P i starvation. We analysed morpho-physiological parameters, expression of key genes, and chemical speciation of phosphorous.…”

“…Although showing a reduction in leaf growth, the sweet variety Della retains anthocyanin accumulation, even at higher levels than Razinieh. This has to be seen on the background of the higher level of sugar in the shoot of Della [29] compared to Razinieh [26][27][28]. Since sugars accumulate under P i starvation [36], it is straightforward to assume that glycosylation of the phenolic moiety and import to the vacuole are crucial for this pigment response.…”

Phosphorus (P) is an essential macronutrient, playing a role in developmental and metabolic processes in plants. To understand the local and systemic responses of sorghum to inorganic phosphorus (Pi) starvation and the potential of straw and ash for reutilisation in agriculture, we compared two grain (Razinieh) and sweet (Della) sorghum varieties with respect to their morpho-physiological and molecular responses. We found that Pi starvation increased the elongation of primary roots, the formation of lateral roots, and the accumulation of anthocyanin. In Razinieh, lateral roots were promoted to a higher extent, correlated with a higher expression of SbPht1 phosphate transporters. Infrared spectra of straw from mature plants raised to maturity showed two prominent bands at 1371 and 2337 cm−1, which could be assigned to P-H(H2) stretching vibration in phosphine acid and phosphinothious acid, and their derivates, whose abundance correlated with phosphate uptake of the source plant and genotype (with a higher intensity in Razinieh). The ash generated from these straws stimulated the shoot elongation and root development of the rice seedlings, especially for the material derived from Razinieh raised under Pi starvation. In conclusion, sorghum growing on marginal lands has potential as a bio-economy alternative for mineral phosphorus recycling.
