A study conducted by the UNNE Faculty of Agricultural Sciences in Argentina has revealed the genetic diversity of feral avocado specimens in the northeast and northwest regions of the country. The research involved analyzing 38 genotypes from various areas, including Salta, Jujuy, Formosa, Chaco, Corrientes, and Santa Fe. The results showed a distinct group of genotypes related to the Mexican race, which is more tolerant of low temperatures, and another group with the Antillean race and interracial hybrids, found in lower elevation areas. The study suggests that the genetic makeup of these feral avocado specimens is closely linked to the local climatic conditions.

The results show a great diversity in the material analyzed and that some specimens come from crosses of commercial cultivars. In Argentina, feral avocado specimens of great potential value for use in selection programs are known. However, the characteristics of these plants and their fruits are practically unknown, since there are no studies that characterize them scientifically. In this regard, from the UNNE Faculty of Agricultural Sciences, which has been promoting local/regional avocado cultivation as a productive diversification strategy, they carried out a project to molecularly characterize specimens of feral avocados from the northeast and northwest regions. Specifically, 38 genotypes prospected in these regions were analyzed, with samples from Salta, Jujuy, Formosa, Chaco, Corrientes, and Santa Fe. The amplification fragments were compared with those obtained for a group of genotypes of commercial interest, from different countries, kept at the La Mayora Subtropical and ...
