Kniphofia Plant Breeding for Compact Height and Early Flowering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of Kniphofia uvaria that exhibits distinct characteristics such as short plant height and early flowering, which are not adequately met by existing varieties.
Innovation Solution
The development of the Kniphofia uvaria variety 'KLEKN22193', resulting from a hand pollination between proprietary varieties 'x14.1.1' and 'x14.1.2', which is vegetatively propagated and reproduces true to type, featuring a compact growth habit and premature flowering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional Kniphofia varieties are used, then they exhibit typical growth patterns, but they have tall plant height and later flowering
Solution Approach 1:
The patent applies parameter changes by selectively breeding and propagating plants with modified growth parameters. The variety 'KLEKN22193' exhibits altered parameters including reduced plant height (40 cm vs typical taller varieties) and accelerated flowering time (18 weeks vs later flowering in conventional varieties). This is achieved through controlled hand pollination between selected parent plants and subsequent vegetative propagation to fix these parameter changes.
Solution Approach 2:
The patent employs preliminary action through selective breeding before commercial propagation. Parent plants with desired traits (shorter height, earlier flowering) are identified and crossed in controlled conditions. The resulting offspring are evaluated and selected, then propagated vegetatively to ensure true-to-type reproduction. This preliminary selection and crossing phase establishes the improved characteristics before large-scale production.
2Shape
If new variety 'KLEKN22193' is developed with short plant height, then it achieves compact growth habit, but it requires controlled breeding program
Solution Approach 1:
The patent uses copying through vegetative propagation (stem cuttings) to replicate the desired plant form and characteristics. Once the ideal plant morphology is achieved through breeding, identical copies are produced asexually. This ensures the compact V-shaped habit and other morphological traits are precisely reproduced in subsequent generations without genetic variation, maintaining true-to-type reproduction.
Solution Approach 2:
The breeding program is segmented into distinct phases: parent plant selection, controlled hand pollination, seed germination, seedling evaluation, and vegetative propagation. This segmentation allows systematic management of the breeding process, with each stage optimized for specific objectives. The segmentation reduces overall complexity by breaking down the complex breeding program into manageable, sequential steps.
