Miniature Rose 'SAValode' Hybridization for Continuous Blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of miniature rose that combines vigor, disease resistance, continuous blooming, and unique flower color, while maintaining fragrance and compact growth habits, which existing varieties have not adequately addressed.
Innovation Solution
A new rose cultivar, 'SAValode', is developed by crossing 'SAVibunda' as the seed parent with an unnamed deep pink seedling of 'SAVasach' as the pollen parent, resulting in a plant with semi-double, golden-yellow blooms, rapid repeat blooming, mild fragrance, few prickles, and dark foliage, characterized by its vigorous growth and abundant bloom production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing miniature rose varieties are used, then they have good vigor and compact growth, but they lack unique flower color and continuous blooming capability
Solution Approach 1:
The patent applies parameter changes by crossing two parent varieties with different genetic parameters to produce offspring with improved traits. The seed parent 'SAVibunda' contributes disease resistance and vigor, while the pollen parent contributes continuous blooming capability, resulting in a new variety that combines these parameters optimally
Solution Approach 2:
The invention uses composite genetics by combining genetic material from two distinct parent varieties. The hybridization process merges the genetic composition of the seed parent (known for disease resistance and vigor) with the pollen parent (known for continuous blooming), creating a composite genetic structure that expresses both sets of desirable traits
2Quantity of substance
If rose varieties with abundant bloom production are selected, then flower quantity increases, but plant size becomes larger than desired for miniature classification
Solution Approach 1:
The patent applies local quality by selecting specific traits from each parent variety while maintaining the miniature plant habit. The new variety exhibits local characteristics of abundant blooming (inherited from the pollen parent) while maintaining the compact size (inherited from the seed parent's miniature classification), creating a localized expression of desirable traits without compromising overall plant dimensions
3Adaptability or versatility
If new varieties are developed through crossing, then unique characteristics are achieved, but breeding time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-selecting parent varieties that already possess the desired traits before crossing. The seed parent 'SAVibunda' was pre-selected for its disease resistance and vigor, while the pollen parent was pre-selected for continuous blooming capability. This preliminary selection reduces the complexity of the breeding program by focusing on combining pre-validated traits rather than screening numerous offspring for rare combinations
