“…Similar results were found by Fonseca et al (2017), in his work to validate the morphoagronomic descriptors used in the protection processes of plant cultivars in Brazil, characterizing six ornamental passion fruit cultivars, in which they identified maximum leaf width (approximately 34%) and petal length (26,17%) as the descriptors that contributed the most to the differentiation of the analyzed cultivars. Lawinscky et al (2014), in the work of morphological characterization and genetic diversity in Passiflora alata Curtis and P. cincinnata Mast, for the 16 morphological descriptors measured, the corona diameter with 43.46%, the petal width with 9.81% and pedicel length with 7.49% were the main contributors to the divergence between the two species.…”

The present study consists of the in situ characterization and selection of minimal morphoagronomic descriptors in Passiflora cincinnata genotypes. Forty-one quantitative morphoagronomic descriptors were used, divided in “Plant and Leaf”, “Floral” and “Fruit”. Principal component analysis were used to eliminate descriptors that were less important in the study of multivariate dissimilarity among genotypes. The formation of groups was carried out using Ward’s hierarchical grouping method. The importance of the characters was estimated through the participation of the components by Singh’s method (1981) in order to verify the similarity between lower participation variables in the components. For the set of descriptors “Plant and Leaf” the characteristics that presented the greatest relative contributions were: maximum leaf width 76.1% and leaf blade length 17.2%. For the set of descriptors “Floral” the characteristics that presented the greatest relative contributions were: pedicel length 42.1%, corona tip diameter 32.6% and petal length 11.8%. For the set of descriptors “Fruit” the characteristic that presented the greatest relative contribution was: number of seeds per fruit 89.2%. From the results obtained, we can infer that from the 41 descriptors, only 15 were relevant for the evaluation of the genetic diversity among the individuals of the population. These descriptors were: titratable acidity, bract length, leaf blade length, petal length, sepal length, pedicel length, corona filament ring length, corona tip diameter, fruit longitudinal diameter, sepal width, maximum leaf width, number of fruits, number of seeds per fruit, bark weight and fruit mass.

“…In 2016, Embrapa released two new hybrid cultivars for landscaping of large areas. Hybrid 'BRS Céu do Cerrado', with bluish flowers, derived from the cross between the species P. incarnata and P. edulis; and 'BRS Rosea Púrpura', with pinkish flowers, originating from the triple cross P. incarnata × P. quadrifaria × P. setacea (Fonseca et al, 2017). Other Brazilian institutions also produced hybrids for ornamental purposes; e.g.…”

The ornamental flower sector has growing over the past years worldwide with potential for further expansion. Among the ornamental plants, Passiflora species have been gaining ground in the market, mainly in European and North American countries. However, the market aiming the use of these species in ornamentation is still poorly explored. The inclusion of passion flower in the list of ornamental plants is related to the peculiar characteristics of the flower as it is complex structure, capacity of flowering all year long and also by the abundance and exuberance of the leaves, which in many species adds an ornamental value. Among the biotechnological tools for the production of ornamental plants, tissue culture has been outstanding in the cloning of elite genotypes, with high phytosanitary quality and large scale production. In addition, it offers possibilities of producing new varieties with characteristics peculiar to the market of ornamental plants. The diversity of wild Passiflora opens perspectives to the conservation, market and production of ornamental Passiflora cultivars.

As a result, RAPD markers have extensively contributed to the selection of parents and development of crossing plans in genetic breeding programs, as well as to the selection of improved plant materials (Bellon, Faleiro, Junqueira, & Fuhrmann, 2014;Fonseca, Faleiro, Junqueira, Barth, & Feldberg, 2017). Therefore, the objective of this study was to evaluate the genetic diversity of 24 genotypes of yellow passion fruit using RAPD molecular markers.…”

Molecular genetic variability studies are essential to complement the agronomic characterization of yellow passion fruit genotypes (Passiflora edulis Sims). Therefore, this study aimed at evaluating the genetic diversity of 24 genotypes of yellow passion fruit obtained from a research program developed by the University of Brasilia and Embrapa Cerrados, using RAPD molecular markers. RAPD markers were obtained from eight decamer primers and converted into a matrix of binary data, from which genetic dissimilarities among genotypes were estimated, and clustering analysis was performed. A total of 54 RAPD markers were obtained, with 6.8 bands per primer on average. From this total, 46 (85.2%) RAPD markers were polymorphic. The OPD10 primer presented the highest number of polymorphic bands. The high percentage of polymorphic markers evidenced the existence of genetic variability among genotypes. Nei’s genetic distance between genotypes ranged from 0.043 to 0.451. Clustering resulted in the formation of at least five groups of similarity.
