Shrub Rose Spromel Continuous Blooming and Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shrub rose varieties often lack attractive, multi-colored blossoms and continuous blooming capabilities, with many displaying unattractive growth habits and limited ornamental value, particularly in Western landscapes.
Innovation Solution
A new shrub rose variety, 'Spromel', is developed through artificial pollination, combining desirable traits from parent varieties to produce abundant, semi-double blossoms with orange to apricot and red coloration, upright and bushy growth, vigorous vegetation, and attractive dark green foliage, suitable for ornamental purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional shrub rose varieties are used, then they may have simple growth habits, but they lack attractive multi-colored blossoms and continuous blooming capabilities
Solution Approach 1:
The patent combines multiple desirable traits from different parent varieties through controlled cross-pollination. The female parent 'MORtoday'×[‘Geisha’×(‘KINbo’בMacivy’)]בSPRoimpress’ contributes vigorous growth and blooming characteristics, while the male parent 'Sprolych' contributes compact habit and multi-colored blossom traits. This merging of parental characteristics produces offspring with both attractive multi-colored continuous blossoms and an desirable upright bushy growth habit.
2Strength
If shrub roses are bred for vigorous growth, then they form strong vegetation, but they may display unattractive growth habits
Solution Approach 1:
The patent achieves local quality optimization by selecting specific parental lines with complementary traits. The female parent provides vigorous vegetative growth strength, while the male parent 'Sprolych' contributes the desirable upright and bushy growth habit. The resulting hybrid exhibits both strong vegetation and attractive compact form, with each parent contributing specific local qualities that complement each other in the offspring.
3Shape
If shrub roses are bred for compact growth habit, then they display neat form, but they lack vigorous vegetation and continuous blooming
Solution Approach 1:
The patent merges the compact growth habit from the male parent 'Sprolych' with the vigorous blooming capability from the female parent lineage. The female parent's complex ancestry including 'MORtoday', 'Geisha', 'KINbo', 'Macivy', and 'SPRoimpress' contributes strong vegetative growth and continuous blooming traits, while the male parent provides the desired compact upright form. The hybrid offspring successfully combines these seemingly contradictory traits.
4Ease of manufacture
If conventional rose varieties are used, then they may have simple coloration, but they lack attractive multi-colored blossoms with continuous blooming
Solution Approach 1:
The patent combines parental varieties with different blossom color characteristics to produce offspring with attractive multi-colored flowers. The female parent contributes yellow to orange-apricot coloration, while the male parent 'Sprolych' contributes orange to red hues. The resulting hybrid exhibits complex multi-colored blossoms with yellow-orange-apricot bases and red centers, achieving color variety through controlled parental selection and cross-breeding.
