Gomphrena hybrida GOM070101 Breeding for Mounding Habit and Vigor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Gomphrena plant cultivars with improved mounding habit, larger long-lasting inflorescences, and distinct flower colors, as existing cultivars may lack vigor, branching, and consistent inflorescence size under varying environmental conditions.
Innovation Solution
The development of Gomphrena hybrida 'GOM070101' through controlled cross-pollination between an unidentified Gomphrena macrocephala and Gomphrena hybrida, resulting in a plant with a mounding habit, vigorous growth, freely branching, large pubescent leaves, and long-lasting red-purple inflorescences.

Engineering Contradiction Analysis
1Shape
If existing Gomphrena cultivars are used, then they may have upright growth habit, but they lack mounding habit and vigorous growth
Solution Approach 1:
The patent applies parameter changes by selectively breeding for specific growth parameters - creating a cultivar with mounding habit (change in plant shape parameter) and vigorous growth (change in growth rate parameter). The cross between Gomphrena macrocephala and Gomphrena hybrida combines desirable parameters from both parents to achieve the target plant habit and vigor.
2Volume of stationary object
If existing Gomphrena cultivars are used, then they may have inflorescences, but they lack large long-lasting inflorescences with consistent size
Solution Approach 1:
The patent changes the inflorescence parameters by breeding for larger size and improved longevity. The cultivar 'GOM070101' produces inflorescences that are both larger and longer-lasting than parent selections, with consistent size across plants grown under varying environmental conditions.
Solution Approach 2:
Rather than selecting for maximum inflorescence size alone, the patent inverts the selection criterion to focus on inflorescence longevity and consistency. The breeders selected plants that maintained inflorescence quality and size over extended periods, resulting in a cultivar where inflorescences last significantly longer while maintaining consistent dimensions.
3Ease of manufacture
If existing Gomphrena cultivars are used, then they may flower, but they lack distinct flower colors
Solution Approach 1:
The patent changes the flower color parameter by breeding for distinct red-purple pigmentation. The cultivar produces flowers with a specific color range (red-purple) that is distinct from parent selections and other cultivars like 'Balboa' (purple), providing clear color differentiation for ornamental purposes.
