Chrysanthemum Cultivar PPP GIRO 09 Consistent August Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Chrysanthemum cultivar that exhibits consistent and distinct characteristics such as large, purple-pink inflorescences, a free branching habit, and specific flowering responses to environmental conditions, which are not met by existing varieties.
Innovation Solution
The cultivar 'PPP GIRO 09' is developed through a cross between 'Cleagar VZP1' and 'GEDI ONE JAM', exhibiting unique traits like consistent flowering in the second week of August, short-day response, and specific horticultural characteristics that differentiate it from other varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cross between 'Cleagar VZP1' and 'GEDI ONE JAM' is performed to create a new cultivar, then unique characteristics such as consistent flowering timing and inflorescence traits are achieved, but the complexity of breeding and selection processes increases
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent varieties with desirable traits ('Cleagar VZP1' for flowering consistency and 'GEDI ONE JAM' for inflorescence characteristics) before crossing. This preliminary selection of parents with complementary traits reduces the complexity of subsequent selection processes while ensuring reliable inheritance of key characteristics like consistent August flowering and inflorescence quality.
2Reliability
If the cultivar is selected for consistent natural season flowering in the second week of August, then flowering timing reliability is improved, but the adaptability to different environmental conditions may be reduced
Solution Approach 1:
The patent applies parameter changes by optimizing the photoperiod sensitivity of the cultivar to achieve consistent flowering response to short days (blooming after 49 days). This specific parameter optimization allows the plant to reliably flower in mid-August under natural season conditions while maintaining the ability to adapt to varying environmental conditions through controlled photoperiod exposure, thus resolving the contradiction between timing consistency and environmental adaptability.
3Quantity of substance
If the cultivar exhibits free branching habit with multiple lateral branches, then the ornamental value and flower production are improved, but the plant height and overall size increase
Solution Approach 1:
The patent applies local quality by developing a cultivar with free branching habit that produces multiple lateral branches (approximately 24 leaves per lateral branch) with inflorescences distributed throughout the plant structure. This creates localized flower production zones throughout the plant rather than concentrating growth in a single tall structure, thereby increasing the number of inflorescences while maintaining a compact overall plant height of approximately 17 cm.
