Verbena KLEVP14490 Red Flower White Eye Mildew Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Verbena variety that exhibits distinct characteristics such as red flower color with small white eyes, large flower size, and good resistance to powdery mildew, which are not adequately met by existing Verbena varieties.
Innovation Solution
The development of the Verbena variety 'KLEVP14490', resulting from a cross-pollination between proprietary varieties 'V975' and 'V980', which demonstrates these desired traits and reproduces true to type in successive generations through vegetative propagation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing Verbena varieties are used, then cultivation is straightforward, but they do not exhibit the desired combination of red flower color with small white eyes, large flower size, and good resistance to powdery mildew
Solution Approach 1:
The patent applies parameter changes by selecting and stabilizing specific phenotypic parameters (flower color red with small white eyes, large flower size, powdery mildew resistance) through controlled cross-pollination and vegetative propagation. The new variety 'KLEVP14490' is developed by changing the genetic parameters of Verbena plants to achieve the desired combination of traits that were not present in existing varieties.
2Adaptability or versatility
If new Verbena varieties are developed through cross-pollination, then desired traits can be achieved, but the development process is time-consuming and complex
Solution Approach 1:
The patent applies segmentation by dividing the development process into distinct stages: cross-pollination between specific parental varieties (V975 and V980), selection of individual plants with desired traits (designated 'KLEVP14490'), and vegetative propagation to reproduce true to type. This segmented approach allows systematic achievement of desired traits while managing the complexity through organized process stages.
Solution Approach 2:
The patent applies copying through vegetative propagation, where the selected plant 'KLEVP14490' is reproduced asexually to create identical copies that maintain the desired traits (red flowers with small white eyes, large size, powdery mildew resistance). This copying mechanism simplifies the propagation of achieved traits without requiring repeated cross-pollination processes.
3Stability of the object's composition
If vegetative propagation is used to reproduce true to type, then genetic consistency is maintained, but the initial development through cross-pollination remains complex
Solution Approach 1:
The patent applies preliminary action by completing the cross-pollination process and selecting the desired plant (KLEVP14490) before implementing vegetative propagation. The complex cross-pollination between varieties V975 and V980 is performed in advance to create the genetically stable parent plant, which is then used for straightforward vegetative propagation to maintain genetic consistency in subsequent generations.
