AbstractThe aim of this study was to investigate the productive traits and fatty acid profiles of eight sweet varieties of Lupinus albus, Lupinus angustifolius and Lupinus luteus cultivated in a Mediterranean environment (Sicily, southern Italy). This is being done to identify the most suitable species, from an agronomical and nutritional point of view, for supporting animal husbandry in this area. Seed yield, oil quantity and oil quality were considerably different depending on the genotype. L. albus showed the highest yield (2.0–2.4 t/ha), 100 seed weight (27.0 g, on average), oil content (70.4–75.5 g/kg), and n−3/n−6 polyunsaturated fatty acid ratio (0.39–0.51), L. angustifolius showed the highest content of saturated fatty acids (21.03–26.66 g/100 g) and L. luteus showed the highest levels of n−6 polyunsaturated fatty acids (47.56–50.85 g/100 g), unsaturated/saturated (4.93–5.62) and polyunsaturated/saturated (3.33–3.99) fatty acid ratios and the best atherogenic (0.06) and thrombogenic (0.09–0.11) indices. The data obtained suggests L. albus as the most interesting lupin species for aiding the crop-livestock food chain and L. luteus as a promising crop due to its high nutritive traits for the Mediterranean environment.
Highlights•Eight guar genotypes were characterized from an agronomic and genetic point of view.•Pods per plant were negatively associated with seeds per pod and 1000 seed weight.•Elite lines in guar were individuated through agronomic traits and AFLP markers.•Monument and Lewis showed the best traits for the Mediterranean environment.•The AFLP approach allowed us to distinguish the geographic origin of genotypes.
Highlights•Inoculation significantly affected nodule number.•The interaction of inoculation x phosphate fertilizer significantly affected pods per plant.•Bacteria inoculation enhanced seed and galactomannan yield per hectare.•Galactomannan content (%) was not influenced by inoculation and phosphate fertilization.•The present research proves inoculation as a valuable and sustainable practice in guar cultivation.
