Molecular characterization of papaya genotypes using AFLP markers

Abstract: -Due to the low genetic variability reported in the commercial plantations of papaya (Carica papaya L.), the objective of this study was analyze the genetic diversity of 32 genotypes including cultivars, landraces, inbred lines, and improved germplasm using the AFLP technique (Amplified Fragment Length Polymorphism). The genetic distance matrix was obtained using the Nei and Li genetic distance and clustering was performed using the unweighted pair-method with arithmetic mean (UPGMA). Using 11 combinations of … Show more

“…The varieties of the Solo group are planted in many regions of the world, producing fruit with desirable characteristics for export, with red flesh, small size and weight between 300 and 650 g. Fruits of the Formosa group have red flesh and average size between 1000 and 1300 g. According to Oliveira et al (2011), the Formosa group consists of commercial hybrids that have gained space in domestic and foreign markets, with strong sales growth in Europe, Canada and the United States.…”

“…A number of genetic divergence studies have also been carried out with different accessions of papaya (Carica papaya L.) (Ramos et al, 2011;Quintal et al, 2012;Oliveira et al, 2011;Lucena and Dantas, 2015). Therefore, the objective of this study was to evaluate, by means of variables, the genetic variability among 59 accessions of papaya that have not been previously evaluated in studies of genetic diversity.…”

“…Tal fato pode indicar que os alelos presentes nas linhagens parentais do híbrido ainda não se encontram totalmente fixados. Oliveira et al (2011), estudando a diversidade genética via AFLP em genótipos de Carica papaya, observaram que a cultivar Sunrise foi mais próxima genotipicamente de uma linhagem endogâmica estudada (CMF-L30-08), quando comparado com genótipos landraces (CMF 233) na mesma espécie.…”

“…Silva et al (2007) empregaram com sucesso os marcadores RAPD para monitorar o avanço de gerações de autofecundação no progenitor Formosa do híbrido Uenf/Caliman 01. Ramos et al (2012) (KIM et al, 2002;OLIVEIRA et al, 2011), microssatélites (SSR -Simple Sequence Repeat) (EUSTICE et al, 2008;OCAMPO PÉREZ et al, 2006), RFLP (Restriction Fragment Lenght Polymorphism) (ARADHYA et al, 1999) e ISSR (COSTA et al, 2011). adicionou-se tampão de extração.…”

“…For instance, Stiles et al (1993) used 11 random amplified polymorphism DNA (RAPD) molecular markers to evaluate the genetic relationships among ten papaya varieties. Other similar studies were developed by Kim et al (2002) and Oliveira et al (2011) to estimate diversity and to assess the genetic relationships among papaya accessions based on amplified fragment length polymorphism (AFLP) markers. However, RAPD and AFLP markers are considered dominant markers and present disadvantages such as a low content of genetic information per locus, an inability for genotypic discrimination, low reproducibility (especially RAPD), a large number of steps and a requirement for high-quality DNA (AFLP).…”
