“…From the total number of markers, 82% were polymorphic in RAPD, and 91.2% were polymorphic in ISSR, showing the highgenetic variability among the six cultivars. A high polymorphism indicating the high-genetic variability of the Passiflora genus by RAPD markers has already been reported by Bellon et al (2009Bellon et al ( , 2014, Viana et al (2010), Castro et al (2011), andCerqueira-Silva et al (2012). This fact have been verified also by Santos et al (2011b), Costa et al (2012), and Sousa et al (2015) by using ISSR markers.…”

-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.

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.

“…The high coefficients of variation in the plots and in the experiment reported in table 2 probably arise from the natural variation that typically occurs in field experiments and from the large genetic variability of the passion fruit cultivar, which derives from seven genotypes from different Brazilian regions. Castro et al (2011) also observed large variability among passion fruit vines grown in the Federal District (centre west region of Brazil).…”

Organic polyculture of passion fruit, pineapple, corn and cassava: the influence of green manure and distance between espaliers

et al. 2014

The organic fruit crop should incorporate the principles of sustainable agriculture, with a guarantee of productivity coupled with ecological diversity, using techniques of policultive with regional species. The aim of the study was to evaluate the effect of the green manure crops [Canavalia ensiformis (jack beans), Crotalaria spectabilis (sunn hemp), Pueraria phaseoloides (tropical kudzu), Arachis pintoi (peanut forage) and spontaneous plants] and distance between espaliers on the yields of Passiflora edulis f. flavicarpa (passion fruit), Ananas comosus (pineapple), Zea mays (maize), Manihot esculenta (cassava) and biomass in organic polyculture in the state of Acre, Brazil. The randomized block design experiment comprised plots encompassing the space between the rows of passion fruits (espaliers located 3 m or 4 m apart), and subplots that contained the green manure crops. Green biomass yield by jack beans, sunn hemp and tropical kudzu was greater than that provided by peanut forage and spontaneous plants. The polyculture of passion fruit, pineapple, maize and cassava presented a high overall yield (44462 kg ha-1). The land-use efficiency of the polyculture system was between 2.45 (with sunn hemp) and 2.77 (with tropical kudzu) times greater than that achieved by individual monocultures. The yields of passion fruit (with tropical kudzu as cover crop) and pineapple (with spontaneous plants as green manure) were enhanced by some 72 and 34%, respectively, when cultivated in plots comprising 3 m-spaced espaliers in comparison with plots containing 4 m-spaced espaliers.
