Abstract

SILVA, Clemilton Alves da et al. Genetic divergence among accesses of "cajazinho" (Spondias mombin L.) in the North of Espírito Santo State, Brazil. Rev. Ceres [online]. 2014, vol.61, n.3, pp.362-369. ISSN 0034-737X.  http://dx.doi.org/10.1590/S0034-737X2014000300010.

The study of genetic diversity is a fundamental tool in plant breeding programs, providing important information on characterization, conservation and utilization of the genetic resources available. The aim of this study was to assess the genetic diversity of 35 cajazinho genotypes (Spondias mombin L.), based on physical and chemical characteristics of fruits. The study evaluated 35 cajazinho genotypes (S. mombin L.) in the north of Espírito Santo. The experiment was arranged in a complete randomized design wit 35 treatments and five repetitions to investigate genetic variability among the genotypes of S. mombin. Data were subjected to analysis of variance. Genetic diversity was foung among the S. mombin L. progenies, being the most divergent the progenie C 3. Both the Tocher optimization and UPGMA were partially concordant with the formation of heterotic groups of S. mombin L. progenies; the characteristics that most contributed to the genetic divergence were total titrable acidity (33.33%), fruit weight (28.68%) and the polar diameter (9.80%).

Keywords : physical and chemical characteristics; multivariate analysis; UPGMA; Tocher.
