Resumen:
The existence of six varieties of Acacia cavenAcacia caven
has been established on the basis of differences in fruit
morphology. Taking into account the controversial evidence
provided by morphology, molecular markers might
be a useful tool for evaluation of genetic differentiation
among varieties of A. caven. Given this fact, we conducted
a parallel analysis of genetic and phenotypic diversity
among and within six varieties of A. caven with the
objective of determining whether the varieties described on
morphological grounds represent genetically differentiated
entities. Distinction of the six varieties was examined using
morphological and random amplified polymorphic DNA
(RAPD) markers. RAPD data were analyzed with basic
descriptive genetic statistics, by hierarchical genetic analysis,
and by discriminant analysis. Morphological data
were studied by means of univariate, multivariate, and
discriminant analysis. The results from analysis of variance
components for morphological data are in concordance
with those from molecular markers, because most of the
variance is found within populations. The results, obtained
here from molecular markers, support the taxonomic differentiation
of the six varieties studied.A. caven. Given this fact, we conducted
