Genetic variability in pecan genotypes in Brazil

Pecan is a perennial plant, deciduous and monoecious fruit tree (having pistillate and staminate flowers on the same plant). Based on the resulting genetic distance matrix, the cluster analysis was performed by the Unweighted Pair Group Method with Arithmetic Mean (UPGMA), with the help of the NTSYS...

Description
Summary:Pecan is a perennial plant, deciduous and monoecious fruit tree (having pistillate and staminate flowers on the same plant). Based on the resulting genetic distance matrix, the cluster analysis was performed by the Unweighted Pair Group Method with Arithmetic Mean (UPGMA), with the help of the NTSYS-pc Numerical Taxonomy and Multivariate Analysis System, version 2.02 (Rohlf, 1998). Due to their low DNA quality, six genotypes - 'Caddo', 'Chickasaw', 'Mohawk', Success 02, 'Importada' and Selection МЮ1 - also had to be removed from the analysis. Based on the cluster analysis, with a cophenetic correlation coefficient was 73.10% with the genetic similarity matrix, four large groups were identified (Figure 2).
