Abstract
Assessment of genetic diversity is an essential component in germplasm characterization and utilization. In this study, we determined genetic diversity of 10 coconut ( Cocos nucifera L.) accessions from six locations in Hainan province, China by using microsatellite markers. From the used 26 simple sequence repeat (SSR) markers, we detected a total of 188 alleles with an average of 7.23 alleles per locus and an average polymorphism information content of 0.575. Expected heterozygosity ( He ) of Haikou green Tall (HK-GT) was significantly higher than that of other Tall types, while the lowest heterozygosity was observed in Sanjiang green Tall (SJ-GT). At the genetic differentiation index ( F ST ) of 0.078, they showed a low level of population differentiation. In addition to diversity parameters, Bayesian assignment tests and cluster analysis were used to determine population structure. Our study provided a better understanding of individual identities, genealogical relationships and geographical origin of coconut germplasm, and it could contribute to more efficient conservation and utilization of this germplasm.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
