“…[15], the ovarian diameter averages of some passion fruit species vary between 13 mm and 52 mm, while the height varies between 13 mm and 90 mm. One of the characteristics that most contributes to the genetic variability of passion fruit species is the ovary height, which is 25% important [16]. According to [17] the most efficient pollinating agents of passion fruit are the mamangavas (Xylocopa spp.…”

Yellow passion fruit is a native tropical fruit tree whose cultivation has evolved very rapidly in Brazil; therefore, studies on the ecology of reproduction are needed. The study of pollen viability is an important tool to observe the male potential of the species. The objective of this study was to estimate pollen viability, pollen/ovule ratio and floral biology of Passiflora edulis Sims in organic cultivation located in Bananeiras, PB, and Brazilian. The study was developed in a completely randomized design, using ten flower buds in the pre-anthesis. The analyses performed in the biology laboratory

“…The sugar content and acidity of the fruits may vary due to the environmental factors and cultivation practices, such as the quality of sunlight, temperature, and factors closely linked to altitudinal variations. Acidity highly affects the quality of the beverage produced from the pulp (Oliveira et al, 2017).…”

Simultaneous analysis studies of several agronomic traits in cultivated plants make it possible to identify phenotypic and genotypic differences due to environmental variations, such as altitude. Therefore, the objective was to evaluate, through multivariate analysis of agronomic, physicochemical and physiological characters, passion fruit hybrids cultivated in different environments. The hybrids used were Gigante Amarelo, Rubi do Cerrado and Sol do Cerrado, cultivated in the southern region of Espírito Santo in four municipalities/environments: Marataízes (41 m), Jerônimo Monteiro (104 m), Alegre (711 m), and Ibitirama (1016 m). The agronomic characters of the plants, the physical-chemical characteristics of the fruits and the physical, biochemical and physiological qualities of the seeds were analyzed. The Singh method was used to determine the most important differentiating characters between hybrids growing in different environments. Based on these characters, a dissimilarity matrix was generated and a principal coordinate analysis was performed. It was observed that the pulp yield was influenced by altitude. The three hybrids showed greater performance in terms of agronomic characters at altitude (41 m) than at altitude (104 m). The Sol do Cerrado hybrid showed high performance in the physical-chemical characteristics of the fruits at altitude (104 m).

“…For instance, the genus Passiflora L. (Passifloraceae) included more than 500 species of passion fruit, which makes it apt for use in breeding programs, considering that the available genetic variability allows for the selection and genetic recombination with these species REFLORA, 2018). Passion fruit variability can be evidenced by morphological, agronomic, ecological, and molecular characteristics, and fruit characteristics are the variabilities that contributed the most to genetic variability (OLIVEIRA et al, 2017).…”

Over several past centuries, specific plant populations have been carefully selected to filter strains with higher agronomic performance. Genetic variability is most essential for successful selection. The Passiflora genus offers great inter- and intra-specific variability. This study aimed to evaluate the physical characteristics of the genotypes of the elite passion fruit (Passiflora alata) for selection purpose. We considered the physical traits of fruit mass, longitudinal and equatorial diameters, peel thickness and color, and pulp mass and volume without and with seeds and pulp yield. The sources of variation for the analysis of variance included the fruits of 8 elite genotypes, with 3 replications, whose means were compared by Tukey’s test at 1% probability. We also performed multivariate analysis and correlation between these characteristics. Statistical differences were noted between elite genotypes for most of the tested traits. The elite 7 genotype presented with the highest seedless pulp yield in relation to the fruit and the largest fruit mass. Cluster analysis and graphic dispersion revealed a tendency for clustering of the elite genotypes based on their fruit shape. The tested population showed genetic variability, which allowed new selection cycles toward gaining pulp yield and fruit mass.
