Meipicdevoj Rose Breeding for Disease Tolerance and Blooming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a Groundcover rose plant with a low mounding growth habit, abundant and continuous summer blooming, attractive white double blossoms, dense dark green foliage, and tolerance to Marsonia, which differs from existing varieties in growth habit and blossom coloration.
Innovation Solution
The new Rosa hybrida Groundcover rose plant, named 'Meipicdevoj', was created through artificial pollination combining the 'Ausblush', 'The Fairy', and 'Korbin' varieties, exhibiting a spreading growth habit, white double blossoms, dense foliage, and good disease tolerance, suitable for landscape ornamentation, and stable through asexual propagation methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rose varieties are used, then they may have established growth habits and fragrance, but they lack the desired combination of low mounding growth habit, continuous summer blooming, white double blossoms, dense foliage, and Marsonia tolerance
Solution Approach 1:
The patent combines three different rose varieties ('Ausblush', 'The Fairy', and 'Korbin') through controlled pollination to create a new variety that merges their desirable traits: low mounding growth habit from one parent, continuous blooming capability from another, and disease tolerance from the third, achieving a combination not present in any single parent variety
Solution Approach 2:
The invention selects specific parental varieties that each contribute particular local qualities or traits to the offspring, with each parent providing specific characteristics (growth habit, blooming pattern, disease resistance) that are then combined in the new variety
2Manufacturing precision
If selective breeding is performed to achieve desired characteristics, then the new variety exhibits unique traits, but the process requires multiple generations of study and selection
Solution Approach 1:
The patent performs preliminary selective breeding and characterizes parental varieties before the actual cross-breeding, pre-identifying which varieties possess the desired traits (low growth habit, continuous blooming, disease tolerance) to minimize the time required for subsequent selection and stabilization of the new variety
3Ease of manufacture
If artificial pollination is used to create the new variety, then specific parental traits can be combined, but the process requires controlled study and selection of multiple seedlings
Solution Approach 1:
The patent employs natural biological processes (pollination, seed development, plant growth) to achieve the breeding objectives, allowing the plants themselves to perform the complex genetic recombination and selection processes rather than requiring artificial intervention at each stage

AI summary
A new and distinct Groundcover rose plant is provided which commonly forms clusters on a tardive basis attractive white double blossoms with excellent reblooming during the summer. The growth habit is low and mounding. The plant exhibits strong vegetation and attractive very dense dark green foliage with a semi-glossy aspect. The tolerance to disease is good particularly with respect to Marsonia. The attractive dark green foliage contrasts nicely with the white blossom coloration. The new variety is well suited for growing as attractive ornamentation in the landscape.
