“…There were no genetic differences between populations of P. platycephala, as found in the previous study by Morais et al (2022). The recent study, analyzed by nucleotide polymorphism loci, found that most of the diversity (99.06%) was distributed within populations; so, according to the genetic structure, the two populations could be considered a single population (Morais et al 2022). No differences between populations of P. platycephala could be explained, in that case the gene flow was effective to prevent divergences.…”

The objective of the study was to determine whether Parkia platycephala families with superior morphophysiological traits perform consistently across four stages of early development (plantlets, seedlings, and juveniles at 34 and 60 months), as a means to assess the possibility of conducting preselection. For 21 morphophysiological traits, the following genetic parameters were estimated: heritability, coefficients of variation (genetic, relative, and environmental), accuracy, genetic and phenotypic correlation, percentage of coincidence (PC) of the best families, effective population size, and inbreeding in three progeny tests conducted under laboratory, nursery, and field conditions. Families of P. platycephala showed significant phenotypic and genotypic differences. The traits evaluated show genetic control. The percentage of coincidence between the best families was more accurate when the selection intensity was greater than 50% (PC ≥ 52%). Based on the evaluated traits, a pre-selection strategy at the juvenile stage for P. platycephala was researched to effectively identify superior families.
