Passion fruit plant ‘Grand Passion’

A new and distinct cultivar of Passion Fruit plant named ‘Grand Passion’ is disclosed, characterized by its light satiny purple flower color, deep yellow fruit pulp color, and the balance between the acidity and brix presence in its pulp. The new variety is a Passiflora, normally used for outdoor ornamental purposes.

Description

Latin name of the genus and species: Passiflora edulis x edulis flavicarpa.

Variety denomination: ‘Grand Passion’.

BACKGROUND OF THE INVENTION

Co-breeders Ángel Gabriel Álvarez Ramírez and Manuel Acosta Gascón have been developing a breeding program for new Passiflora varieties since 2016, carrying out crossings and/or pollinations of different varieties of the same species. It was in 2017, when they observed that in one of the vines of one of the crossings between an unnamed, unpatented variety of Passiflora edulis (female parent) and an unnamed, unpatented Passiflora edulis flavicarpa (male parent) the fruit had different characteristics not only to those of its parents but also to the other varieties of Passiflora edulis varieties, especially its size, color, flavour and scent. First asexual reproduction was conducted in San Bartolome de la Tone, Huelva, Spain in 2017. This vine was selected and grafted onto Passiflora edulis flavicarpa, undergoing evaluation for two seasons in 2018 and 2019, showing the same characteristics as the mother vine. These vines were obliterated by the “Filomena” storm in January 2021, except for one specimen which was planted and re-grafted that same year in 50 new specimens. During the 2020, 2021 and 2022 seasons, it was observed that the fruit from the selection maintained the distinctive characteristics of the selected parent.

SUMMARY OF THE INVENTION

The cultivar ‘Grand Passion’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Grand Passion’. These characteristics in combination distinguish ‘Grand Passion’ as a new and distinct Passiflora cultivar:

    • 1. Produces larger fruit than the seed parent, and smaller fruit than the pollen parent.
    • 2. Light purple fruit skin color.
    • 3. Medium green leaf color.
    • 4. Deep yellow pulp color.

PARENT COMPARISONS

Plants of the new cultivar ‘Grand Passion’ are comparable to the seed parent, variety Passiflora edulis. The two Passiflora varieties are similar in most horticultural characteristics; however, the new variety ‘Grand Passion’ differs in the following:

    • 1. Fruit of the new variety is larger than fruit of the seed parent.
    • 2. Fruit color of the new variety is a lighter purple than fruit color of the seed parent.

Plants of the new cultivar ‘Grand Passion’ are comparable to the pollen parent Passiflora edulis flavicarpa. The two Passiflora varieties are similar in most horticultural characteristics; however, the new variety ‘Grand Passion’ differs in the following:

    • 1. Fruit of the new variety is smaller than fruit of the pollen parent.
    • 2. Fruit color of the new variety is light purple, while fruit color of the pollen parent is yellow.

COMMERCIAL COMPARISONS

Plants of the new cultivar ‘Grand Passion’ are comparable to the commercial variety Passiflora ‘PANDORA’, unpatented. The two Passiflora varieties are similar in most horticultural characteristics; however, the new variety ‘Grand Passion’ differs in the following:

    • 1. Leaf color of the new variety is green, while the leaf color of this comparator is reddish-orange.
    • 2. Flowers of the new variety are smaller than flowers of this comparator.
    • 3. Seeds of this comparator are wider than seeds of the new variety.
    • 4. Fruit skin color of the new variety is light purple, while fruit skin color of this comparator is reddish-purple.
    • 5. First harvest of the new variety is earlier than the first harvest of this comparator.
    • 6. The new variety is self-fertile, while this comparator is self-sterile.

Plants of the new cultivar ‘Grand Passion’ are comparable to the commercial variety Passiflora ‘SILESIA’, unpatented. The two Passiflora varieties are similar in most horticultural characteristics; however, the new variety ‘Grand Passion’ differs in the following:

    • 1. Leaf blade of this comparator is longer and broader than the leaf blade of the new variety.
    • 2. Leaf blade of this comparator has a deeper sinus and a weaker degree of blistering than the leaf blade of the new variety.
    • 3. Petiole of the new variety is shorter than the petiole of this comparator.
    • 4. Bract length of the new variety is longer than the bract length of this comparator.
    • 4. Sepals of the new variety are longer and narrower than sepals of this comparator.
    • 5. Petals of the new variety are longer than petals of this comparator.
    • 6. Flowers of the new variety have a more deeply-colored spotted ring in the throat than flowers of this comparator.
    • 7. Fruit lenticels of the new variety are less conspicuous than fruit lenticels of this comparator.
    • 8. Seeds of the new variety are larger than seeds of this comparator.
    • 9. Fruit pulp color of the new variety is orange-yellow, while fruit color of this comparator is orange.

 DETAILED BOTANICAL DESCRIPTION

For the following description of the new variety of Passiflora, the data has been observed and obtained under the climatic and environmental conditions existing in the evaluation fields located northern hemisphere in San Bartolomé de la Tone, Huelva, Spain, at approximately 128 meters above sea level, with a relative humidity of 30% in summer and 65% to 75% in winter. Minor variations in maturity dates and production may be due to agronomic management such as irrigation, fertilization, pruning and climate change. All main identification of colors is according to The ROYAL HORTICULTURAL SOCIETY (R.H.S.) Colour Chart 2015 edition.
