Abstract
‘GRAtgx’ is a new and distinct floribunda type Rosa hybrid cultivar which is characterized by the combination of an upright to semi-weeping growth habit, good resistance to Diplocarpon rosae and Podosphaera pannosa, nearly continuous flowering, distinct cerise flowers with yellow stripes and flecks and a cream yellow reverse, a moderate rose fragrance, and the stability of these characteristics from generation to generation. The new cultivar is generally suited to landscape applications.
Description
Latin name of genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Rosa hybrid.
Variety denomination: The inventive variety of Rosa hybrid disclosed herein has been given the variety denomination ‘GRAtgx’.
Parentage: ‘GRAtgx’ is a seedling selection which resulted from the controlled cross-pollination of an unnamed Rosa hybrid female breeding line (not patented) and an unnamed Rosa hybrid male breeding line (not patented). Both parents, developed by the same inventor and never commercially released, exhibited traits deemed commercially significant and desirable.
After many years of trialing, the female parent was confirmed to possess a combination of desirable traits such as high resistance to rose black spot disease, complete resistance to powdery mildew, and cerise pink flowers with yellow stripes and flecks and a yellow petal reverse, borne on a bushy plant growing to 1.2 m tall and wide. The male parent was selected for use in breeding after trialing confirmed the presence of a modern flower color. During the spring of 2014, the female parent was emasculated and was manually pollinated with pollen from the male parent. In autumn of 2015, seed was collected from hips produced by the female parent and a number of seedlings were grown to a mature size, including the claimed plant. These progeny were further evaluated for desirable traits such as black spot disease resistance and original flower color, and in January of 2016 the claimed plant was first observed. In January of 2017, after further evaluation for desirable traits, the claimed plant was deemed to be garden-worthy and suited to widespread cultivation. It was given the denomination, ‘GRAtgx’.
Asexual Reproduction: Asexual propagation of ‘GRAtgx’, by way of softwood stem cuttings, was first performed in May of 2016 at the inventor's nursery in Highfields, Australia. Through more than twelve subsequent generations, the unique features of this cultivar have proven to be stable and true to type.
The following characteristics have been repeatedly observed and represent the distinguishing characteristics of the new Rosa cultivar ‘GRAtgx’. These traits, in combination, distinguish ‘GRAtgx’ as a new and distinct cultivar.
-
- 1. Rosa ‘GRAtgx’ exhibits an upright to semi-weeping growth habit; and
- 2. Rosa ‘GRAtgx’ exhibits high resistance to the plant pathogen, Diplocarpon rosae, commonly referred to as rose black spot disease; and
- 3. Rosa ‘GRAtgx’ exhibits nearly continuous flowering; and
- 4. Rosa ‘GRAtgx’ exhibits a double flower type; and
- 5. Rosa ‘GRAtgx’ exhibits cerise pink flowers with yellow stripes and flecks and a yellow petal reverse; and
- 6. Rosa ‘GRAtgx’ exhibits flowers with a moderate to strong rose fragrance.
The FIGURE illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical flower of ‘GRAtgx’.
The following observations and measurements, made in February of 2018, describe averages of two own-root specimens of one year old ‘GRAtgx’ plants. The plants were grown outdoors in a garden bed of a red krasnozem soil in full sunlight, at the inventor's nursery in Highfields, Australia. No shade or supplemental light was provided. Temperatures ranged from approximately 17 to 35 degrees Celsius during the day and 7 to 18 degrees Celsius at night. Standard practices for irrigation, fertilizer and pest control were applied at appropriate times during the growing season. The plants were pruned three times during the growing season using accepted techniques for rose pruning.
Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘GRAtgx’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2007 Fifth Edition except where common terms of color are used.
A botanical description of ‘GRAtgx’ and comparisons with the parents and the most similar commercial cultivar of Rosa hybrid are provided below.
