Abstract As climate variability continues to impact agricultural systems, identifying genetic factors that contribute environmental adaptation will be essential for optimizing breeding strategies the development of resilient varieties. Through human cultivation and naturalization, Cannabis sativa has dispersed globally, adapting a range conditions across various climates latitudes. We combined raw data from multiple public sources conduct an Environmental Genomic Selection (EGS) analysis on 149 samples, assess how different populations relate their conditions. Exploring Estimated Adaptive Values (GEAVs) bioclimatic variables can facilitate selection parental material adapted specific condition. further explore potential mechanisms local by characterizing individual marker effects which underlie these GEAV scores. To interpretation, we used previously described groupings (Basal, Hemp-type, Drug-type feral, Drug-type). Distinct patterns emerged population groups with drug-type (Type I) group showing consistently narrow ranges, whereas feral showed broader distribution, often having high GEAVs precipitation variables. A key variable difference was seen in monthly average values, revealing seasonal response samples. marker-effect differences between indicated this samples are sourced geographic regions have monsoons, they may traits conferring flood tolerance (water logging) could introgressed into other backgrounds. The basal also exhibited broad ranges several traits, indicating valuable resource introgression enhance resilience. These findings underscore importance incorporating diverse germplasm programs improve resilience changing EGS provides fast method enable climate-conscious while gaining mechanistic information. Ultimately, hope such strategy support climate-resilient varieties tailored both current future challenges.
