-The objective of this work was to validate the morphoagronomic descriptors used in the protection processes of plant cultivars in Brazil, by characterizing six cultivars of ornamental passion fruit. The BRS Rubiflora, BRS Rosea Púrpura, BRS Céu do Cerrado, BRS Roseflora, BRS Estrela do Cerrado, and BRS Pérola do Cerrado cultivars, 33 morphoagronomic descriptors, and two molecular markers were used. The categorical morphoagronomic descriptors were analyzed by frequency distribution and multivariate analyses. The quantitative morphoagronomic descriptors were subjected to the analysis of variance and to the comparison of the means of each cultivar. The random amplified polymorphic DNA (RAPD) and the inter-simple sequence repeats (ISSR) markers were used for molecular analysis. A high-validation rate was observed for the morphoagronomic descriptors used in the protection of plant cultivars. The analyses of variance showed significant differences between the quantitative descriptors, and the molecular markers confirmed the genetic differences among the cultivars. There was a high correlation between the calculated distances based on the categorical morphoagronomic descriptors and molecular markers. The morphoagronomic descriptors and molecular markers are useful and complementary for the characterization and differentiation of cultivars.Index terms: Passiflora, molecular markers, multivariate analysis, plant cultivar protection. Caracterização morfoagronômica e molecular de cultivares de maracujazeiro ornamentalResumo -O objetivo deste trabalho foi validar os descritores morfoagronômicos utilizados nos processos de proteção de cultivares no Brasil, por meio da caracterização de seis cultivares de maracujazeiro ornamental. As cultivares BRS Rubiflora, BRS Rosea Púrpura, BRS Céu do Cerrado, BRS Roseflora, BRS Estrela do Cerrado e BRS Pérola do Cerrado, 33 descritores morfoagronômicos e dois marcadores moleculares foram utilizados. Os descritores morfoagronômicos categóricos foram analisados por meio da distribuição de frequência e análises multivariadas. Os descritores morfoagronômicos quantitativos foram submetidos à análises de variância e à comparação entre médias das cultivares. Os marcadores "random amplified polymorphic DNA" (RAPD) e "inter-simple sequence repeats" (ISSR) foram usados para análise molecular. Observou-se alta taxa de validação dos descritores morfoagronômicos utilizados na proteção de cultivares. As análises de variância mostraram diferenças significativas entre os descritores quantitativos das cultivares, e os marcadores moleculares confirmaram as diferenças genéticas entre elas. Houve alta correlação entre as distâncias calculadas com base nos descritores morfoagronômicos categóricos e nos marcadores moleculares. Os descritores morfoagronômicos e os marcadores moleculares são úteis e complementares para a caracterização e a diferenciação das cultivares.Termos para indexação: Passiflora, marcadores moleculares, análise multivariada, proteção de cultivares.

“…Knowledge of genetic diversity is fundamental for the conservation and maintenance of genetic resources in breeding programs (Costa et al, 2012) and helps understanding kinship between genotypes and identifying the best parents to obtain higher genetic gains in segregating populations (Viana et al, 2003;Ganga et al, 2004).…”

“…The altitudinal gradient may influence the distribution of genetic variation in and between plant populations and genetic diversity may change according to the altitude. Genetic diversity in the genus Passiflora has been studied by DNA molecular markers (Costa et al, 2012;Cerqueira Silva et al, 2014a;Cerqueira Silva et al, 2014b;Lougon et al, 2014). Between the markers, microsatellites are preferred because they are codominant and multi-allelic (Vieira et al, 2016).…”

Genetic diversity in passion fruit plants at different altitudes

et al. 2019

Passion fruit belongs to the Passifloraceae family and to the genus Passiflora, which is economically relevant. This genus is originated from Brazil, which has the greatest genetic diversity. The altitudinal gradient may influence the distribution of genetic variation in and between plant populations and genetic diversity may change according to the altitude. The objective of this study was to evaluate the genetic diversity in passion fruit in different altitudes of Espírito Santo, using microsatellite markers (SSR) and inter simple sequence repeat (ISSR). Five matrixes plants of each species of Passiflora edulis Sims f. flavicarpa Degener, P. edulis Sims and P. alata Curtis were studied at three altitudes (low, medium and high) in the state of Espírito Santo. For each sample, 13 microsatellite markers developed for Passiflora edulis and 14 ISSR primers were amplified according to the greatest number of polymorphic fragments and amplification quality. Low values of alleles were found (1-3), and low heterozygosity was expected and slight PIC values were found, while for the ISSR analysis a large number of bands per primer were detected and high polymorphism. The P. alata Curtis species was the most divergent to P. edulis Sims f. flavicarpa Deg. and P. edulis Sims. The SSR and ISSR markers enabled us to indicate differences among the species, but they did not always show variation between and within similar species. The populations of low altitude are different from the others, independent of the species and the marker used. The habitat has a highly important influence on genetic diversity.
