Petunia Cultivar DRAY307 Mounded Habit Yellow Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Petunia varieties with distinct ornamental characteristics for commercial applications, as existing varieties lack specific traits such as unique flower colors, branching habits, and flowering abundance.
Innovation Solution
The development of the Petunia cultivar 'DRAY307' through controlled breeding, which exhibits a mounded, ball-shaped habit, medium vigor, large yellow flowers, and abundant flowering, differing from its parents and comparators in terms of growth habit, flower size, and color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional Petunia varieties are used, then they have established growth habits and flowering patterns, but they lack unique ornamental characteristics such as distinct flower colors, specific branching habits, and flowering abundance
Solution Approach 1:
The breeding program systematically altered key parameters including flower color (yellow with orange throat), growth habit (mounded, ball-shaped), branching density (very branched), and flower size (large, 6cm diameter) to create a cultivar with distinctive ornamental characteristics that differ from conventional varieties
2Adaptability or versatility
If new breeding combinations are attempted to achieve unique traits, then distinct ornamental characteristics may be obtained, but the stability and true-to-type reproduction of these traits across generations becomes uncertain
Solution Approach 1:
The cultivar underwent rigorous evaluation across multiple generations and environmental conditions to confirm trait stability. The feedback from observing 25+ successive generations and multiple environmental exposures confirmed that the unique characteristics (yellow flowers, mounded habit, abundant flowering) are reliably inherited and stable
Solution Approach 2:
The breeding process involved selecting for specific parameter combinations that proved stable across generations, including the distinctive yellow flower color with orange throat, mounded growth habit, and very branched structure, ensuring reliable true-to-type reproduction
3Shape
If large flower size is selected for ornamental value, then aesthetic appeal increases, but the overall plant vigor and branching abundance may be reduced
Solution Approach 1:
The breeding program successfully changed multiple parameters simultaneously to achieve large flowers (6cm diameter) while maintaining very branched growth and abundant flowering, a combination not typically found in conventional varieties where large flowers often come at the expense of overall plant vigor
