Abstract
A new and distinct Quercus rubra tree named ‘QRMTF’ is disclosed, characterized by dark green mature foliage and a significant red flush on new growth, which occurs through the Summer. Trees have been observed to have good heat tolerance in the Southern United states and a rapid growth rate. The new variety is a Quercus tree, typically used for landscapes and gardens.
Description
Latin name of the genus and species: Quercus rubra.
Variety denomination: ‘QRMTF’.
The new cultivar is a product of a planned breeding program. The new variety was discovered growing as a seedling among a group of crossbred Quercus rubra trees at a tree farm in Washington, Ga. The inventor made this discovery in the Summer of 2013. The exact seed and pollen parents cannot be identified.
Asexual reproduction by grafting of the new cultivar ‘QRMTF’ was first performed during February of 2014 at a farm in Washington, Ga. The cleft grafting system developed by the inventor has resulted in progeny that have proven the characteristics of the new variety to be genetically stable. This grafting process involved taking cuttings in February, being grafted, and being placed in calloused chambers for approximately three weeks. They are then moved into 3″×6″ tree band pots and placed in humidity chambers for approximately four weeks. Furthermore, these observations have confirmed that the new variety represents a new and improved variety of Quercus rubra tree as particularly evidenced by the superior heat tolerance. These genetic traits can be consistently reproduced by asexual propagation.
The cultivar ‘QRMTF’ 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 ‘QRMTF’ grown in Washington, Ga. These characteristics in combination distinguish ‘QRMTF’ as a new and distinct Quercus rubra cultivar:
-
- 1. Darker green foliage than typical for species.
- 2. Fast growth rate
- 3. Significant red flush on new growth, continuing through the Summer months.
- 4. Heat tolerance observed in Southern United States.
The exact parent varieties cannot be identified.
Plants of the new cultivar ‘QRMTF’ are similar to plants of Quercus rubra ‘Aurea’ (unpatented), in most horticultural characteristics, however, plants of the new cultivar ‘QRMTF’ differ in the following:
-
- 1. The new variety produces red new foliage; this comparator produces yellow new foliage.
Plants of the new cultivar ‘QRMTF’ are similar to plants of Quercus rubra ‘Splendens’ (unpatented), in most horticultural characteristics, however, plants of the new cultivar ‘QRMTF’ differ in the following:
-
- 1. Fall color of the new variety is a different shade of red than this comparator.
- 2. The new variety produces new foliage with a distinctive red coloration which continues through the Summer months.
The accompanying photograph in FIG. 1 illustrate a fully leafed tree with new growth in a field, during late June. The red flush of new growth can be seen.
All trees illustrated are field grown in Washington, Ga. Trees in FIGS. 1, 2 and 3 are approximately 3 years from planting into the field, 4 years old from grafting. The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
In the following description, color references are made to The Royal Horticultural Society Colour Chart 2007 except where general terms of ordinary dictionary significance are used. The following observations and measurements describe ‘QRMTF’ plants grown outdoors and in a nursery in Washington, Ga. Plants are approximately 2 years old, in a 3 gallon nursery container. Temperatures ranged from 5° C. to 10° C. at night to 18° C. to 27° C. during the day. Measurements and numerical values represent averages of typical plant types.
