Chamelaucium LUNA Cultivar Breeding for Unique Bloom Times
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Chamelaucium varieties with specific ornamental characteristics such as unique bloom times, flower petal attitudes, and sizes that differentiate them from existing varieties for commercial applications.
Innovation Solution
The development of the Chamelaucium cultivar 'LUNA' through planned breeding, which exhibits distinct traits like a mid-December to March blooming season, semi-erect flower petals, small flower size, and white flowers, achieved through asexual reproduction by terminal vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional Chamelaucium varieties are used, then they have established bloom times and flower characteristics, but they lack unique ornamental characteristics that differentiate them for commercial applications
Solution Approach 1:
The patent applies parameter changes by modifying key botanical characteristics including bloom time (December-March), flower petal attitude (semi-erect), and flower size (small) to create a distinct cultivar. These parameter modifications were achieved through controlled breeding between parent varieties '95.1' and 'Atar L', resulting in a new cultivar with differentiated ornamental features while maintaining species stability.
2Adaptability or versatility
If new breeding is conducted to create unique varieties, then distinctive ornamental traits are achieved, but the breeding process and generation selection require significant time
Solution Approach 1:
The patent implements preliminary action through a structured breeding program that pre-selected parent varieties with complementary traits. The cross between '95.1' and 'Atar L' was deliberately designed to achieve specific ornamental characteristics, allowing the breeder to predict and select for desired traits in the offspring, thereby reducing the time required for random selection and acceleration of variety development.
3Stability of the object's composition
If asexual reproduction is used to maintain cultivar characteristics, then genetic stability is achieved, but the propagation process requires controlled environmental conditions
Solution Approach 1:
The patent applies copying through asexual reproduction by terminal vegetative cuttings, which creates genetically identical copies of the parent plant. This method ensures that the unique ornamental characteristics of cultivar 'LUNA' are precisely replicated across generations without genetic variation, maintaining stability while using a relatively simple propagation technique compared to sexual reproduction.

AI summary
A new and distinct Chamelaucium cultivar named ‘LUNA’ is disclosed, characterized by small white flowers with uniquely semi-erect petals. Flower production begins in mid-December and continues until March. The new variety is a Chamelaucium, normally producing cut flower stems, or as a garden or container plant.
