Abstract
Objective: The present investigation determined the key genetic reserve areas that host populations of wild cotton relatives in Mexico, through the use of Geographic Information Systems and modeling.
Design/methodology/approach: A database was used with 2,594 records of collections of the genus Gossypium, the data come from the year 1933 to the year 2024; A map was created to visualize the geographical distribution of the species and another for genetic diversity where the Shannon Diversity Index was ap-plied.
Results: 80% of the records of wild cotton relatives are concentrated in G. hirsutum, G. aridum and G. davidsonii, with 58.8, 14.3 and 6.7% respectively, con-firming that Mexico is the center of diversity for G. hirsutum. Five key areas with very high genetic diversity were identified in the states of Oaxaca and Michoacán.
Findings/conclusions: In the states of Guerrero, Baja California Sur and Sonora, areas with a high concentration of some of the Gossypium species were identified, so they could be considered key areas for the conservation of the genetic di-versity of Gossypium.
