ABSTRACT:
BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Leptospermum plant, botanically known as
Leptospermum liversidgei
, and hereinafter referred to by the cultivar name ‘BY11’.
The new Leptospermum is a product of a planned and controlled breeding program conducted by the Inventor in Montrose, Victoria, Australia. The objective of the breeding program is to create new Leptospermums with and compact and upright plant habit and containing high concentrations of citronellal and/or the citronellal analogs, pulegol and isopulegol. These essential oils have effective Mosquito-repellant properties.
The new cultivar originated from a self-pollination by the Inventor of the Inventor's proprietary selection of
Leptospermum liversidgei
identified as ‘BY18’. The cultivar ‘BY11’ was discovered and selected by the Inventor as a plant within the progeny of the stated self-pollination in a controlled environment in Montrose, Victoria, Australia.
Asexual reproduction of the new cultivar by vegetative cuttings taken at Montrose, Victoria, Australia, has shown that the unique features of this new Leptospermum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar ‘BY11’ have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertilizer rate without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BY11’. These characteristics in combination distinguish ‘BY11’ as a new and distinct cultivar:
1. Compact and mostly upright plant habit; terminals occasionally weeping.
2. Closely-spaced small leaves; densely foliated.
3. Numerous light pink flowers.
4. Relatively high concentrations of citronellal and/or its analogs, pulegol and isopulegol.
In side-by-side comparisons conducted by the Inventor in Montrose, Victoria, Australia, the following differences between the new Leptospermum and the parent selection, ‘BY18’, have been observed:
1. Plants of the new Leptospermum are compact and are mostly upright whereas plants of the selection ‘BY18’ have an open, outwardly spreading and weeping plant habit.
2. Plants of the new Leptospermum are more densely-foliated than plants of the selection ‘BY18’.
3. New vegetative growth of plants of the new Leptospermum is green whereas new vegetative growth of the selection ‘BY11’ is reddish.
4. Plants of the new Leptospermum and plants of the selection ‘BY18’ differ in flower color.
5. Plants of the new Leptospermum have a higher concentration of citronellal, pulegol and/or isopulegol than plants of the selection ‘BY18’.
