Spiraea SMNSNFD Compact Habit Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Spiraea varieties with compact and full growth habits, along with improved flower and leaf colors, which existing cultivars do not adequately address.
Innovation Solution
The development of the Spiraea cultivar 'SMNSNFD' through a breeding program aimed at producing compact, vigorous, and strongly flowering plants with stable unique characteristics, achieved through asexual reproduction by softwood cuttings, resulting in a distinct cultivar with enhanced flowering and compact habit compared to its parent and commercial counterparts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If existing Spiraea cultivars are used, then they provide basic flowering and growth, but they lack compact habit and strong flowering characteristics
Solution Approach 1:
The breeding program systematically varied genetic parameters through controlled cross-pollination between selected parent plants, creating offspring with optimized combinations of compact growth habit and strong flowering. The new cultivar 'SMNSNFD' exhibits significantly reduced plant height and spread compared to parents, while simultaneously displaying increased flower production and intensity.
2Adaptability or versatility
If open pollination breeding is used, then genetic diversity is increased, but the pollen parent cannot be identified or controlled
Solution Approach 1:
The breeding program implemented systematic observation and recording of flowering patterns, fruit development, and seed set characteristics to infer pollen parent identity. By monitoring the timing and pattern of fruit set on the seed parent 'Flachenfuller' and correlating with nearby potential pollen donors, the inventor gathered feedback information to identify the unknown pollen parent contribution to cultivar 'SMNSNFD'.
