“…In a review about chemical composition of quinoa with studies prior to the year 2000 [41], it was reported that the fat content in quinoa seeds ranges between 1.8% and 9.5%. When compared to widely consumed cereals internationally, the values of Chimborazo ecotype quinoa are higher than those of wheat [42][43][44] and rice [45][46][47][48]. It is important to highlight that several investigations have reported that the fat in quinoa is mostly composed of unsaturated fatty acids, which are beneficial for health [35,49].…”

Quinoa is known for its high nutritional value and adaptability; however, there is a lack of data about the chemical composition of quinoa produced in Ecuador, especially the Chimborazo ecotype. Our research aims to evaluate the nutritional components of Chimborazo quinoa. This knowledge (chemical composition) can help to improve cultivation and farmers’ understanding. Samples were collected from 49 plots at four altitude ranges (3000–3200; 3201–3300; 3301–3400; 3401–3533) m.a.s.l. Each sample of 2 kg quinoa was cleaned, dried (32 °C/15 h), and stored at −20 °C before analyzing water activity, proximate composition, mineral content, antioxidant activity, and functional compounds. The data were analyzed using ANOVA and mean comparison, Pearson correlation, and principal component analysis. The Chimborazo ecotype shows protein content comparable to or exceeding other global quinoa cultivars. Statistical analysis revealed that altitude had a minimal influence on quinoa’s chemical composition, resulting in overlapping altitude-based clusters. Complex relationships between quinoa variables were identified, which varied with altitude. These findings suggest that cultivation of high-quality quinoa across a range of altitudes is feasible without compromising its intrinsic quality. Moreover, the extensive and diverse results from our study provide a solid foundation for further plant breeding and the development of specialized quinoa varieties.

“…The values of the parameters determined in the analyzed wheat cultivars are presented in Table 1. These parameters are considerably influenced by external factors, including environmental conditions and weather, and they can differ even within the same cultivar [52][53][54][55][56]. In the present study, the average dry basis (DB) moisture content of the wheat grain was determined within a relatively narrow range, from around 12.3% DB (SMH 87) to around 13.1% DB (Askalon and Bamberka), which indicates that the examined grain batches can be stored over prolonged periods of time and used in the production process.…”

A new approach to determining the friabilin content of wheat grain was proposed. Electropherograms were taken, and the intensity of the friabilin bands was compared in the analyzed wheat cultivars and the cv. Chinese Spring. The friabilin content indicator was calculated in the grain of 17 common wheat cultivars, which differed mostly in their crude protein content and hardness index (HI). The basic properties of the kernels were measured in each wheat cultivar, and the correlations between the measured parameters and the friabilin content indicator were determined. In the analyzed wheat cultivars, the friabilin content indicator ranged from around 0.21 to around 0.77. This indicator was significantly correlated with the kernel length, thickness, mass, vitreousness, HI, and rupture force. The strongest correlation was observed between the friabilin content indicator and kernel length. An increase in the mean kernel length from around 5.4 mm to around 8.0 mm decreased the friabilin content indicator by approximately 51%. After the mean kernel length had been calculated in a given wheat cultivar, a certain value of the friabilin content indicator could be ascribed to this cultivar, and the energy consumption during grain grinding or milling could be partly predicted. In the group of analyzed wheat cultivars, the process of grain grinding would be the most energy-intensive in the cvs. Ceres, SMH200, and SMH214 and the least energy-intensive in the cvs. Chinese Spring, Julius, and Askalon.

“…Because the endosperm structure of durum wheat is hard, and the glassiness ratio in the grain is high, semolina yields and semolina shine values are higher than those of bread wheat (Troccoli, 2000). GPC is a complex trait strongly affected by environmental factors (Manai-Djebali et al, 2021). The grain quality of durum wheat is related to GPC because of its direct association with the production of high-quality pasta (Dalla Marta et al, 2011).…”

“…The quality of the end product is highly linked to the grain structure, which is affected by the genotype, environment, and genotype x environment (Schulthess et al, 2013). Various environmental parameters such as soil properties and agricultural practices, have an important influence on the industrial quality parameters of durum wheat grains (Calzarano et al, 2018;Manai-Djebali et al, 2021).…”

Wheat is usually grown as a rainfed crop, and no irrigation is applied in most production fields. This study was undertaken to evaluate to quality characteristics of durum wheat germplasm in three different environments under rainfed and irrigated field conditions during 2019-2020, 2020-2021 and 2021-2022 growing seasons. Supplemental irrigations (SI) were applied during critical vegetative stages (spiking and grain filling) in irrigated treatments while plants only received water from natural rainfall in rainfed treatments. Field experiments were performed in a 12x12 Alpha Lattice design with two replications. Grain protein content (GPC), starch content, wet gluten content and test weight were examined for one hundred and twenty-five durum wheat genotypes which consist of fifty-one local cultivars, twenty-one foreign cultivars, forty-four gene bank landraces (ex situ) and fifteen landraces (in situ). SI resulted in decrease in GPC and wet gluten content but increase in starch content. Ex situ landraces (17.48%) and in situ landraces (16.62%) had higher GPC mean values under both rainfed and irrigated conditions in 2019/2020 and 2020/2021 growing seasons. Correlation coefficient was 0.90 between GPC-wet gluten content while it was -0.82 and -073 between starch content-GPC and starch content-wet gluten content, respectively. The effect of SI was more evident in local and foreign cultivars in all three environments compared to landraces. Our results indicated that ex situ landraces has a great potential in terms of grain quality characteristics. The high genotypic diversity and improved quality characteristics in landraces provided extensive insights for future studies to improve crop quality in areas with limited irrigation opportunities.
