Geranium Noorthava Cultivar Large Flower and Extended Bloom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new cultivar of Geranium wallichianum that exhibits larger flowers with distinctive veining and a longer blooming season, as existing cultivars like 'Jolly Bee', 'Buxton's Variety', and 'Pink Penny' have smaller flowers and different coloration.
Innovation Solution
The cultivar 'Noorthava' is developed, characterized by large light blue-violet flowers with dark purple veins, a strong growth habit, and an extended blooming season of about 8 weeks, achieved through asexual propagation by division and tissue culture, which stabilizes its unique traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If existing cultivars of Geranium wallichianum are used, then they have typical flower size for the species, but the flowers are smaller and lack distinctive veining
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a seedling with modified floral parameters (larger size, more conspicuous veining) from open pollination of Geranium wallichianum. The asexual propagation methods preserve these changed parameters across generations, creating a stable cultivar that consistently exhibits the improved flower characteristics.
2Duration of action of moving object
If existing cultivars are used, then they have a standard blooming season, but the blooming period is shorter
Solution Approach 1:
The patent changes the temporal parameter of the plant by selecting a seedling with an extended blooming period. Asexual propagation by division and tissue culture ensures this extended duration parameter is reliably reproduced in successive generations, achieving both longer blooming and trait stability.
Solution Approach 2:
The patent performs preliminary selection of the seedling in 2008 based on its extended blooming performance, then establishes it as a stable cultivar through asexual propagation before commercial release. This preliminary identification and stabilization ensures the long blooming season is reliably captured in the cultivar.
3Strength
If existing cultivars are used, then they have moderate growth habit, but the growth is less vigorous and foliage is less healthy
Solution Approach 1:
The patent changes the growth parameters by selecting a seedling with stronger growth habit and healthier foliage. Multiple asexual propagation methods are employed to ensure these strength parameters are consistently reproduced, creating a robust cultivar.
Solution Approach 2:
The patent uses tissue culture as an intermediary propagation method to efficiently multiply the selected plant while maintaining its superior growth characteristics. This intermediary technique allows for large-scale production of plants with consistent strong growth habits.
