Sedum Touchdown Jade Cultivar Breeding for Compact Habit and Large Inflorescences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Sedum telephium cultivars lack desirable traits such as compact growth habit, larger inflorescences, and distinct flower colors, which are essential for aesthetic and nursery growth advantages.
Innovation Solution
The development of 'Touchdown Jade', a new Sedum telephium cultivar with light pink flowers, blue-green leaves, rose-red veins, strong rose pink stems, and a multiple crown, dense, low mounding habit, achieved through asexual propagation and exhibiting excellent vigor, addresses these shortcomings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Sedum telephium cultivars are used, then basic growth is maintained, but compact growth habit and larger inflorescences are not achieved
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific morphological parameters including compact growth habit, multiple crowns, and enlarged inflorescence size. The cultivar 'Touchdown Jade' exhibits these altered parameters compared to conventional Sedum telephium, achieving both compact shape and larger inflorescences through controlled breeding programs that modify growth parameters.
2Ease of manufacture
If conventional Sedum cultivars are used, then basic flower production is maintained, but distinct flower colors and aesthetic appeal are not achieved
Solution Approach 1:
The patent directly applies color changes by developing a cultivar with distinctive light pink flowers and blue-green foliage with rose-red veins. The color transformation is achieved through selective breeding that modifies pigment production, creating a reliable and consistent color scheme across the cultivar that enhances aesthetic appeal while maintaining reliability through true-to-form propagation.
3Productivity
If conventional propagation methods are used, then basic plant reproduction is achieved, but consistent transmission of unique characteristics is not guaranteed
Solution Approach 1:
The patent applies copying through asexual propagation methods including division and tissue culture that create exact genetic copies of the parent plant. This ensures that the unique characteristics of 'Touchdown Jade'—its compact habit, multiple crowns, light pink flowers, and blue-green foliage—are consistently transmitted to progeny without genetic variation, maintaining both productivity and compositional stability.
