Allium IFALCOD Cultivar Compact Habit and Flowering Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new compact and freely-flowering Allium plants with attractive flowers and good container and garden performance, as existing varieties lack compactness and consistent flowering habits.
Innovation Solution
The development of a new cultivar, 'IFALCOD', resulting from a planned breeding program, which exhibits an upright habit, moderately vigorous growth, early and frequent flowering, dense white flower inflorescences, and good garden performance, distinguishing it from its parent and similar varieties like 'Milennium' with purple flowers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Allium varieties are used, then they have basic flowering capability, but they lack compactness and consistent flowering habits
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that control plant height, growth rate, and flowering behavior. The cultivar 'IFALCOD' exhibits modified parameters including reduced plant height (15-25 cm), controlled growth rate, and extended flowering period (6-8 weeks), resolving the contradiction between compactness and flowering consistency
Solution Approach 2:
The breeding program inverted the traditional approach by first selecting for compact growth habit and then maintaining flowering reliability, rather than prioritizing flowering and accepting variable plant size. This inversion is evident in the selection criteria that prioritize upright compact habit while ensuring reliable flowering performance
2Volume of moving object
If Allium plants are bred for compact growth habit, then plant size is reduced, but flowering frequency and reliability may decrease
Solution Approach 1:
The patent utilizes parameter changes by modifying genetic parameters that control the relationship between plant size and flowering. The cultivar 'IFALCOD' maintains a compact volume (15-25 cm height) while achieving high flowering frequency through selected genetic parameters that decouple size from reproductive output, allowing multiple flowering cycles per season
Solution Approach 2:
The breeding program introduced dynamics by creating a plant that can transition between growth phases and flowering phases multiple times within a season. The compact plant size does not limit the number of flowering cycles, as the plant dynamically resets after each flowering event, enabling repeated productivity from the same compact structure
3Speed
If Allium plants are bred for vigorous growth, then growth rate increases, but plant compactness is reduced
Solution Approach 1:
The patent applies parameter changes by selecting for specific growth rate parameters that achieve vigor without excessive size expansion. The cultivar 'IFALCOD' exhibits moderately rapid growth that quickly establishes the plant, then transitions to a maintained compact form, optimizing both establishment speed and final compact habit through controlled parameter expression
