Genus and species plant named: Hylocereus undatus.
Variety denomination: ‘DF2’.
The plant resulted from selection among a population of seedlings derived from a controlled cross carried out in 2013 between ‘RF’ (seed parent) (not patented) and ‘LD5’ (pollen parent) (not patented) in Tien Giang, Viet Nam. ‘DF2’ was identified in 2016 as having potential as a new variety due to its attractive fruit, good eating quality and canker tolerance. ‘DF2’ was first asexually propagated by cuttings in 2017, in Tien Giang, Viet Nam. The resulting plants were planted in clonal trials and underwent further evaluation. The plants were subsequently found to be true to type demonstrating that the characteristics of the new variety are stable and transmitted without change through succeeding propagations.
‘DF2’ is characterised by its attractive medium sized fruit with medium red to purple flesh and excellent flavour; dark pink to red skin color and tolerance to canker (Neoscytalidium dimidiatum).
Asexual reproduction of this new variety by cuttings and in vitro shows that the aforementioned characteristics are true to form and are established and transmitted through succeeding propagation.
The accompanying photographs show typical specimens of the tree, foliage and fruit of the new variety as depicted in colors as nearly true as is reasonably possible to make the same in a color illustration of this character.
The following is a description of the new variety with color terminology in accordance with The Royal Horticultural Society Colour Charts (R.H.S.C.C.) 2015 edition.
The specimens described were grown in Tien Giang, Viet Nam. The observations were made in the 2018-2020 season on 1-2 year-old plants.
