Salvia splendens cultivar SGRSA05-1 upright habit and fertility
Solution Overview
Problem
Existing Salvia splendens varieties lack large, upright plant habits and diverse flower colors, with some being sterile and having limited environmental adaptability.
Innovation Solution
The development of the Salvia cultivar 'SGRSA05-1' through self-pollination and asexual reproduction, resulting in a vigorous, upright plant with a long flowering period, unique salmon-orange flowers, and higher calyx retention, which is stable across varying environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional Salvia splendens varieties are used, then they are easier to cultivate, but they lack large upright plant habits and diverse flower colors
Solution Approach 1:
The patent applies parameter changes by selectively breeding plants with specific genetic parameters to achieve desired physical characteristics. The breeding program targeted plants with genes for upright growth habit, larger size, and diverse flower colors (salmon, orange, red combinations), transforming the typical trailing, smaller, single-color Salvia splendens into a new cultivar with fundamentally different physical parameters.
2Adaptability or versatility
If some Salvia splendens varieties are used, then they have limited environmental adaptability, but they may have uniform appearance
Solution Approach 1:
The patent employs self-service through self-pollination of the selected parent plant to produce seeds that naturally inherit and stabilize the desired traits. This self-fertilization method allows the plant to reproduce itself while maintaining the unique combination of upright habit, large size, and diverse flower colors, creating a stable cultivar that true-breeds these characteristics across generations.
3Reliability
If sterile Salvia splendens varieties are used, then they have uniform flower characteristics, but they lack fertility and seed production
Solution Approach 1:
The patent uses feedback by observing and selecting plants that exhibit both desirable aesthetic traits (upright habit, large size, diverse colors) and reproductive capability. The breeder monitored the parent plant and its offspring for flower color stability, growth habit consistency, and successful seed set, using this feedback to confirm the cultivar meets both aesthetic and fertility requirements before formal registration.

AI summary
A new and distinct Salvia cultivar named ‘SGRSA05-1’ is disclosed, characterized by vigorous plants with a large, upright form and long flowering period. Flowers have salmon corollas with darker salmon-orange calyces. Calyces are persistent and retain their salmon-orange color. The new variety is a Salvia splendens, normally produced as an outdoor garden or container plant.
