Divergência genética entre cultivares de gérbera utilizando marcadores RAPD

Abstract: No processo de produção comercial de mudas de gérbera, a cor da flor é uma das principais características morfológicas de interesse agronômico, sendo uma característica importante em programas de melhoramento genético. A utilização de marcadores moleculares pode servir para direcionar cruzamentos, confirmar novos híbridos ou genótipos mutantes e identificar novos genótipos para fins comerciais. Nesse contexto, o objetivo deste trabalho foi analisar a divergência genética entre seis cultivares de Gerbera jameso… Show more

“…With the binary matrix, we calculated the percentage of polymorphisms obtained per primer and the genetic diversity of the locus or PIC (polymorphism information content), which is an estimate used for the evaluation of the discriminatory power of a locus. To calculate the PIC of each primer, we used the equation proposed by Rezende et al (2009). The genetic dissimilarity estimate between each pair of individuals was calculated by the Jaccard coefficient, using the arithmetic complement.…”

“…The banding profiles showed a total of 42 polymorphic and 7 monomorphic bands from twelve accessions of gerbera. The results show that RAPD is a fast, relatively inexpensive and useful technique for genetic divergence characterization between different cultivars of G. jamesonii (Rezende et al 2009). …”

“…where the information of the primer pij is the frequency of the allele p of the locus i, in the j primer (Rezende et al, 2009). PIC represents the existence of variability, which will be higher with higher values of PIC.…”
