The objective of this study was to evaluate the genetic variability of natural rubber latex traits
among 44 elite genotypes of the rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Müell. Arg.].
Multivariate analysis and machine learning techniques were used, targeting the selection of parents
that demonstrate superior characters. We analyzed traits related to technological or physicochemical
properties of natural rubber latex, such as Wallace plasticity (P0), the plasticity retention index [PRI
(%)], Mooney viscosity (VR), ash percentage (Ash), acetone extract percentage (AE), and nitrogen
percentage (N), to study genetic diversity. Multivariate [unweighted pair group method with
arithmetic means (UPGMA) and Tocher)] and machine learning techniques [K-means and Kohonen’s
self-organizing maps (SOMs)] were employed. The genotypes showed high genetic variability for
some of the evaluated traits. The traits PRI, Ash, and PO contributed the most to genetic diversity. The
genotypes were classifed into six clusters by the UPGMA method, and the results were consistent
with the Tocher, K-means and SOM results. PRI can be used to improve the industrial potential of
clones. The clones IAC 418 and PB 326 were the most divergent, followed by IAC 404 and IAC 56. These
genotypes and others from the IAC 500 and 400 series could be used to start a breeding program.
These combinations ofer greater heterotic potential than the others, which can be used to improve
components of rubber latex quality. Thus, it is important to consider the quality of rubber latex in the
early stage of breeding programs MenosThe objective of this study was to evaluate the genetic variability of natural rubber latex traits
