The coancestry coefficientxyθxy) was significant up to 38 m in PJ the population and 71 m in AM. Individual palm outcrossing rates were predominantly high (tm tm = 0.985) and the paternity correlation (rp(m) rp(m) = 0.02) was significantly low, indicating a high probability of the occurrence of half-sibs. Compared to other palm species, the studied populations show high levels of genetic diversity. Our results confirm that A. aculeata is primarily allogamous, with no significant paternity correlation, and seeds should be harvested from at least 40 trees to ensure high levels of genetic diversity in seed collection programs.
