“…The highest concentration in the 3 products evaluated was iron, and it was detected in the highest concentration in the bean pod (100.30591 ppm), followed by high concentrations of manganese, with the squash seed having the highest content of 31.83205 ppm. The concentrations reported by some authors are different from those of this research, but in the studies they report that there was significant difference in the content of essential trace elements between the species evaluated; this indicates the morphological variability present between variants of each species and the potential they have as sources of essential trace elements (Darrudi et al, 2018). Zinc concentrations in this study were 35.43 ppm, similar…”

Objective: To determine the proximal and mineral composition analysis of of castilla squash seeds (C. moschata), green pea (P. sativum) and pinto saltillo green bean (P. vulgaris). Design/methodology/approach: The contents of macronutrients (carbohydrates, fats, crude fiber, protein, and ash) and micronutrients (minerals) of the evaluated species were determined using the AOAC standard procedures, and the quantification of minerals was performed by mass spectrometry with inductively coupled plasma. A variance analysis and means comparison were performed with Tukey’s test (α = 0.05). Results: The squash seeds with shells contain 291,500 ppm of protein, 417,000 ppm of fat, 66,700 ppm of carbohydrates, 134,000 ppm of crude fiber, 972,319.678 ppm of phosphorus, 3,380.09158 ppm of potassium and 3,183.2744 ppm of magnesium. The whole pea pod has 230,600 ppm of protein, 17,200 ppm of fat, 456,000 ppm of carbohydrates, 220,800 ppm of crude fiber, 5,438.18,991 ppm of phosphorus, 7,349.23753 ppm of potassium and 1,719.56882 ppm of magnesium. The whole green bean pods had a content of protein (185100 ppm), fat (2540 ppm), carbohydrates (377500 ppm), fiber (208000 ppm), phosphorus (6068.44661 ppm), potassium (15626.9991 ppm) and magnesium (17222.16567 ppm)). Study limitations/implications: Studies on the chemical characteristics of other agroindustrial residues should be carried out. Findings/conclusions: The foods analyzed have adequate characteristics to satisfy the demands with respect to some macronutrients and micronutrients. They can optimize the availability of nutrients in the generation of natural or synthetic foods that can change the future.

“…From these results, the predicted selection gains were significant and up to 29.39 g for MSF and 0.26 t•ha -1 for PS (Table 1). Consistent with our results, remarkable variability in characteristics related to seed production, such as MSF and PS, in the C. moschata germplasm has been reported previously (Lima Neto, 2013;Darrudi et al, 2018;Oliveira et al, 2020).…”

Cucurbita moschata D. seed oil contains approximately 75% unsaturated fatty acids, with high levels of monounsaturated fatty acids and antioxidant compounds such as vitamin E and carotenoid, constituting a promising food in nutritional terms. Associated to this, the Brazilian germplasm of C. moschata exhibits remarkable variability, representing an important source for the genetic breeding of this vegetable and other cucurbits. In this context, the present study evaluated the productivity and profile of the seed oil of 91 C. moschata accessions from different regions of Brazil and maintained in the Vegetable Germplasm Bank of the Federal University of Viçosa (BGH-UFV). A field experiment was conducted between January and July 2016. The tested C. moschata accessions showed high genetic variability in terms of characteristics related to seed oil productivity (SOP), such as the mass of seeds per fruit and productivity of seeds, providing predicted selection gains of 29.39 g and 0.26 t ha -1 , respectively. Based on the phenotypic and genotypic correlations, greater SOP can be achieved while maintaining high oleic acid content and low linoleic acid content, providing oil of better nutritional and chemical quality. In variability analysis, the accessions were clustered into five groups, which presented different averages for SOP and fatty acid content of seed oil; approach that will guide the use of appropriate germplasm in programs aimed at genetic breeding for SOP and seed oil profile. Per se analysis identified BGH-4610, BGH-5485A, BGH-6590, BGH-5556A, BGH-5472A, and BGH-5544A as the most promising accessions in terms of SOP, with average (m+g) of approximately 0.20 t ha -1 . The most promising accessions for higher oleic acid content of seed oil were BGH-5456A, BGH-3333A, BGH-5361A, BGH-5472A, BGH-5544A, BGH-5453A, and BGH-1749, with average (m+g) of approximately 30%, and almost all of these accessions were also the most promising in terms of lower linoleic acid content of seed oil, with average (m+g) of approximately 45%. Overall, part of the C. moschata accessions evaluated in the present study can serve as a promising resource in genetic breeding programs for SOP and fatty acid profile, aiming at the production of oil with better nutritional and physicochemical quality.

“…As with other species, the usefulness of C. moschata germplasm conserved in banks depends on the level and quality of information associated with it [30,31,32,33,49]. The samples of C. moschata maintained by BGH-UFV constitute one of the largest collections of this species in Brazil [34].…”

Winter squash fruits (Cucurbita moschata D.) are among the best sources of vitamin A precursors and constitute sources of bioactive components such as phenolic compounds and flavonoids. Approximately 70% of C. moschata seed oil is made up of unsaturated fatty acids, with high levels of monounsaturated fatty acids and components such as vitamin E and carotenoids, which represent a promising nutritional aspect in the production of this vegetable. C. moschata germplasm expresses high genetic variability, especially in Brazil. We assessed 91 C. moschata accessions, from different regions of Brazil, and maintained at the Federal University of Viçosa (UFV) Vegetable Germplasm Bank, to identify early-flowering accessions with high levels of carotenoids in the fruit pulp and high yields of seed and seed oil. Results showed that the accessions have high variability in the number and mass of seeds per fruit, number of accumulated degree-days for flowering, total carotenoid content, and fruit productivity, which allowed selection for considerable gains in these characteristics. Analysis of the correlation between these characteristics provided information that will assist in selection to improve this crop. Cluster analysis resulted in the formation of 16 groups, confirming the variability of the accessions. Per se analysis identified accessions BGH-6749, BGH-5639, and BGH-219 as those with the earliest flowering. Accessions BGH-5455A and BGH-5598A had the highest carotenoid content, with averages greater than 170.00 μg g-1 of fresh mass. With a productivity of 0.13 t ha-1 , accessions BGH-5485A, BGH-4610A, and BGH-5472A were the most promising for seed oil production. These last two accessions corresponded to those with higher seed productivity, averaging 0.58 and 0.54 t ha-1 , respectively. This study confirms the high potential of this germplasm for use in breeding for promotion of earlier flowering and increase in total content of fruit pulp carotenoids and in seed and seed oil productivity.
