-Growing yellow passion fruit is a profitable activity, with a high demand for labor, and it is practiced especially by family-based farmers. However, the production cost is rather high and a significant part of this cost is associated with the expenses related to fertilization and phytosanitary treatments necessary for obtaining satisfactory yields and high commercial quality fruit. Therefore, the objective of this study was to evaluate the effect of using organic compound in fertilization of plants and alternative products in phytosanitary treatments (Bordeaux mixture, Neem oil and lime sulfur mixture) on the yield and quality of fruits. Yellow passion fruits were submitted to three types of fertilization (mineral, organic and organic-mineral) and two types of phytosanitary treatment ('conventional' and 'alternative'). This experiment evaluated fruit yield (kg/plant) and fruit quality by using the following evaluations: seedless pulp yield, soluble solids content (SS), titratable acidity (TA), SS/TA ratio and vitamin C content. The different types of fertilization did not interfere in fruit yield, however, plants under conventional phytosanitary treatment displayed higher yields. The SS content and TA of the fruits were influenced only by fertilization, where plants that received mineral and organic-mineral fertilization produced fruit with higher contents of SS and TA. Pulp yield, SS/TA ratio and vitamin C content were not influenced by any of the evaluated factors. Regarding cultivation of passion fruit, it is possible to substitute some mineral fertilizers for organic fertilizers with no negative effects on the fruit yield or quality. However, the substitution of pesticides for alternative products compromises fruit yield.Keywords: alternative products, mineral fertilization, organic-mineral fertilization, Passiflora edulis Sims f. flavicarpa Deg.

“…), and, more recently, the purple passion fruit (of the same predominant species, P. edulis). Nonetheless, these other types of passion fruits together account for less than 5% of the home market, thus indicating their regional importance and limited commercialization (Meletti et al, 2005).…”

-Passiflora edulis, the passion fruit native from Brazil, has several common names (such as sour passion fruit, yellow passion fruit, black passion fruit, and purple passion fruit), and presents a wide variability with the different rind colors of its fruits, which are very easy to notice. However, in 1932, Otto Degener suggested that the yellow passion fruit had its origin in Australia through breeding, calling it P. edulis forma flavicarpa, and that it could be distinguished by the color of the fruit, the deeper shade of purple of the corona, and the presence of glands on the sepals. These distinctions do not support themselves, for the glands are common to the species (although they may be absent), and the corona has a wide range of colors, regardless of the color of the fruit. A more critical ingredient is the fact that the external coloration of the fruit is a character of complex inheritance and is not dominant, thus displaying a number of intermediate colors, making it difficult to identify the extreme colors. For the correct scientific naming of agricultural plants, the International Code of Botanical Nomenclature must be used in conjunction with the International Code of Nomenclature for Cultivated Plants, with the selections with significant agronomic characteristics recognized and named cultivars. In accordance with the international convention promoted by the UPOV, of which Brazil is a signatory, several colors (light yellow, yellow, orange yellow, pink red, red, red purple, green purple, purple, and dark purple) can be recognized in order to adequately characterize passion fruit cultivars within the species P. edulis. At taxonomic level, Passiflora edulis Sims must be used for any plant and color of sour passion fruits, in combination with a cultivar name for the selected materials.

PASSIFLORA edulis SIMS: A MANEIRA TAXONÔMICA CORRETA DE REFERIR-SE AO MARACUJÁ-AMARELO (E AOS DE OUTRAS CORES)RESUMO -Passiflora edulis, o maracujá é nativo do Brasil, apresenta vários nomes populares (tais como maracujá-azedo, maracujá-amarelo, maracujá-preto e maracujá-roxo) e grande variabilidade, sendo que diferentes cores da casca do fruto são facilmente observadas. Entretanto, em 1932, Otto Degener sugeriu que o maracujá-amarelo tenha originado através de melhoramento genético, na Austrália, denominando-o como P. edulis forma flavicarpa, e poderia ser reconhecido pela cor do fruto, pela porção colorida da corona, maior e de um arroxeado mais escuro, e pela presença de glândulas nas sépalas. Essa distinção não se sustenta, pois essas glândulas são comuns na espécie (embora possam estar ausentes), e a corona tem grande variação de cores, independentemente da cor do fruto. Ainda mais crítico é o fato de que a coloração externa do fruto é um caráter de herança complexa e não tem dominância, existindo, por isso, várias cores intermediárias e dificuldades para reconhecer quais as cores extremas. Para a correta denominaç...

“…The inherent variability of Passiflora is not restricted to its morphological characteristics [26,27] and the physical and chemical compositions of the fruit and flowers [28,29,30,31] but includes traits important for its survival in natural environments and/or cultivation conditions, such as the resistance of wild species to biotic (fungi, bacteria, nematodes, and viruses) and abiotic stresses (variations in the edaphoclimatic characteristics of macro- and microregions in which Passiflora species naturally occur or are cultivated) [32,33,34]. Such variability may be useful for breeding programs with different end results.…”

Despite the ecological and economic importance of passion fruit (Passiflora spp.), molecular markers have only recently been utilized in genetic studies of this genus. In addition, both basic genetic researches related to population studies and pre-breeding programs of passion fruit remain scarce for most Passiflora species. Considering the number of Passiflora species and the increasing use of these species as a resource for ornamental, medicinal, and food purposes, the aims of this review are the following: (i) to present the current condition of the passion fruit crop; (ii) to quantify the applications and effects of using molecular markers in studies of Passiflora; (iii) to present the contributions of genetic engineering for passion fruit culture; and (iv) to discuss the progress and perspectives of this research. Thus, the present review aims to summarize and discuss the relationship between historical and current progress on the culture, breeding, and molecular genetics of passion fruit.
