Abstract

A new and distinct cultivar of Red Bayberry, botanically known as Myrica rubra, and hereinafter referred to by the name ‘N1MR07’ is described. N1MR07 produces fruit having improved sweetness, a good sugar:acid ratio, a palatable low resin taste along with uniform fruit size and colour. N1MR07 has the following traits: mean fruit diameter is 22.3 mm; mean fruit weight is 7.15 g; fruit colour is red; mean fruit flesh total soluble solids (an indicator of sweetness) is 12.4° Brix; mean fruit flesh titratable acidity is 1.08%; and fruit harvest season in the southern hemisphere is mid-late November.

Description

Botanical denomination: Myrica rubra.
Variety designation: ‘N1MR07’.
BACKGROUND TO THE INVENTION
The present invention relates to a new and distinct cultivar of Red Bayberry, botanically known as Myrica rubra, and hereinafter referred to by the name ‘N1MR07’.
‘N1MR07’ is the product of a selection program started by the inventor in 2002 in a cultivated area of Knoxfield, Victoria, Australia. The primary focus of the selection program is to produce new cultivars of Red Bayberry with fruit having improved sweetness, a good sugar:acid ratio, a palatable low resin taste along with uniform fruit size and colour.
‘N1MR07’ was selected in 2008 from a mature planting of twelve cutting-propagated genotypes which the inventor had originally grown from out-crossed seed collected from China. The inventor is unable to identify either the male or the female parent. A later planting comprising 141 seedlings from a second batch of seed were evaluated for fruit quality in 2010. The combination of traits displayed by ‘N1MR07’ was not found in any of the 141 seedlings. Hence, ‘N1MR07’ is considered to be a unique cultivar.
SUMMARY OF THE INVENTION
The cultivar ‘N1MR07’ was asexually reproduced by clonal propagation, using cuttings or by grafting onto rootstock in Gatton, Queensland, Australia. The original clonal propagation to produce the variety was conducted via vegetative tip cuttings.
The cultivar ‘N1MR07’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, without however any change in genotype.
The following traits have been observed and represent the characteristics of the new Myrica rubra cultivar ‘N1MR07’. These traits in combination distinguish ‘N1MR07’ from all other varieties of Myrica rubra known to the inventor.
    • 1. Mean fruit diameter is 22.3 mm.
    • 2. Mean fruit weight is 7.15 g.
    • 3. Fruit colour is red.
    • 4. Mean fruit flesh total soluble solids (an indicator of sweetness) is 12.4° Brix.
    • 5. Mean fruit flesh titratable acidity is 1.08%.
    • 6. Fruit harvest season in the southern hemisphere is mid-late November.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a digital image showing representative fruit of ‘N1MR06’, ‘N1MR07’, and ‘N1MR09’ displaying the variation in fruit size, shape and colour; harvested November 2011 in Nambour, Queensland, Australia.
FIG. 2 is a digital image showing the whole plant of ‘N1MR07’ in Nambour, Queensland, Australia.
 DETAILED BOTANICAL DESCRIPTION
The following description describes the Myrica rubra cultivar ‘N1MR07’ at 7 years. The vegetative propagule was observed in a test plot maintained with standard management practices for commercial bayberry production in Nambour, Queensland, Australia. Certain characteristics of this variety, such as growth and colour, may change with changing environmental conditions (e.g., light, temperature, moisture, nutrient availability, or other factors). Colour descriptions and other terminology are used in accordance with their ordinary dictionary descriptions, unless the context clearly indicates otherwise. Colour designations are based on the CIE L.C.h colour model and were measured using a Konica Minolta CR-400 Chroma Meter.
