The African oil palm ( Elaeis guineensis Jacq) is a crop that widely distributed in tropical regions around the world; however, this subject to limitations such as rapid trunk growth and susceptibility bud rot red ring diseases particularly South America. To overcome these limitations, national breeding conservation programs have been established, there need identify parental palms from natural populations of American E . oleifera H.B.K. Cortes) with desirable yield morphological traits (i.e., production bunch number) high genetic diversity. However, Peru data related important limited. In study, we characterized estimated diversity using 12 neutral microsatellite markers (simple sequence repeats, SSRs) across 72 individuals belonging germplasm collection located region Ucayali, Peru. Our results showed explained approximately 40.39% variability within Peruvian germplasm. Furthermore, Yield Production was highly correlated two traits: Bunch Number (0.67) Average weight per (0.78). Based on traits, clustering analysis performed three phenotypic groups were identified (1, 2 3) which 1 3 scores associated primarily traits. Microsatellite revealed 143 alleles, 11.92 ± 4.72 alleles locus (A) an expected heterozygosity (He) 0.69 0.045. A structural k = 3), not groups. Interestingly, multiple allele background multilocus phylogenetic relationship analyses. This first report regarding shows preliminary data, highlight importance information set up future steps strategies improve material Overall, novel findings could contribute development local industry
