Saffron (Crocus sativus L.) is one of the most expensive spices in the world. Saffron, prized for its vibrant color, aroma, and taste, is essential in the food industry and traditional medicine. Its culinary uses, therapeutic benefits, and potential antioxidant, anti-inflammatory, and anticancer properties highlight its significant importance. Its genetic diversity has significant implications for cultivation and quality. In this study, genetic diversity among 76 saffron accessions, collected from 13 localities of Taliouin region of Morocco, were evaluated using sequence-related amplified polymorphism (SRAP) markers. A total of 63 polymorphic fragments were produced with an average of total number and polymorphic bands per primer were of 10.5 and 10.16, respectively. Most of the variations among the localities, revealed by the Analysis of Molecular Variance, originated from the within accessions differentiation (81%; p < 0.010). Cluster Analysis, Principal Coordinate Analysis (PCoA), and population structure confirmed the main groups and corroborated genetic homogeneity across accessions. In fact, close relationships were revealed between accessions from different locations, showing that there was no relationship between genetic divergence and geographical locality. This investigation represents a pivotal advance towards fostering sustainable development and bolstering the economic empowerment of the saffron farming communities in Morocco.

Climate change exacerbates water scarcity in semi-arid and arid regions, particularly across the Mediterranean Basin, posing severe challenges to food security and freshwater availability. Non-conventional water resources, such as desalinated seawater, are increasingly considered for supplementing irrigation; however, their exclusive use can induce osmotic stress, nutrient imbalances, and soil alkalinity, thereby limiting crop performance. This study evaluated the agronomic, and physiological impacts of blending freshwater (FW) and desalinated seawater (DSW) for two zucchini (Cucurbita pepo L.) cultivars, Radia and Kayssar, under greenhouse conditions. Five irrigation regimes were tested: T1 (FW^100%), T2 (FW^75%-DSW^25%), T3 (FW^50%-DSW^50%), T4 (FW^25%-DSW^75%), and T5 (DSW^100%). Moderate blending, particularly T2 and T3, optimized vegetative growth, biomass accumulation, and reproductive performance, maximum yields were obtained under T3, reaching 6.65 kg/plant for Radia and 5.49 kg/plant for Kayssar, while fruit quality, including caliber and soluble solids content (°Brix), was also highest under this regime. These findings support the suggestion that implementing such combined/blended irrigation regimes can enhance vegetative growth, yield, and fruit quality in the face of increasing water scarcity and energy constraints.
