Hierarchical genetic clusters for phenotypic analysis Agronomy
Matta, Luiza Barbosa da; Tomé, Lívia Gracielle Oliveira; Salgado, Caio Césio; Cruz, Cosme Damião; Silva, Letícia de Faria.
Methods to obtain phenotypic information were evaluated to help breeders choosing the best methodology for analysis of genetic diversity in backcross populations. Phenotypes were simulated for 13 characteristics generated in 10 populations with 100 individuals each. Genotypic information was generated from 100 loci of which 20 were taken at random to determine the characteristics expressing two alleles. Dissimilarity measures were calculated, and genetic diversity was analyzed through hierarchical clustering and graphic projection of the distances. A backcross was performed from the two most divergent populations. A set of characteristics with variable heritability was taken into account. The environmental effect was simulated assuming . For hierarchical...
