Petunia DPECLABRAY Cultivar Breeding for Mounded Habit and Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for new Petunia hybrida varieties with distinct ornamental characteristics such as growth habit, flower color, size, and abundance, which existing varieties fail to provide effectively.
Innovation Solution
The development of the Petunia hybrida cultivar 'DPECLABRAY' with a mounded growth habit, medium vigor, light blue large flowers, and abundant flowering, achieved through controlled breeding and stable asexual reproduction.

Engineering Contradiction Analysis
1Length of stationary object
If a Petunia variety is bred for large flower size, then flower size is improved, but plant vigor and branching may deteriorate
Solution Approach 1:
The breeding program systematically adjusted genetic parameters to achieve a balance between flower size and branching. The cultivar 'DPECLABRAY' was selected from a controlled cross between Petunia 'cv. 13-7456' and Petunia 'cv. 13-7686', where parental traits were combined and optimized through selective breeding to produce plants with both large flowers and good branching characteristics.
2Productivity
If a Petunia variety is bred for abundant flowering, then flowering abundance is improved, but flower size may deteriorate
Solution Approach 1:
The breeding program optimized the genetic parameters to simultaneously achieve abundant flowering and large flower size. The cultivar 'DPECLABRAY' exhibits both traits through controlled cross-breeding and selection, where the genetic makeup was adjusted to balance reproductive output with individual flower development.
3Shape
If a Petunia variety is bred for mounded growth habit, then plant shape is improved, but plant height may deteriorate
Solution Approach 1:
The breeding program focused on creating localized density variations in the plant structure. The cultivar 'DPECLABRAY' was selected for its mounded growth habit where branching and foliage density are concentrated in the lower and middle portions of the plant, creating a compact, rounded form rather than uniform vertical growth.
