KORpucoblu Climbing Rose Breeding for Disease Resistance and Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rose cultivars lack uniform growth and flowering, abundant attractive foliage, and resistance to diseases, making them unsuitable for landscapes and gardens.
Innovation Solution
The development of a new Rosa hybrida cultivar, 'KORpucoblu', through controlled cross-pollination breeding, which exhibits a climbing growth habit, vigorous growth, excellent disease resistance, abundant flowers, very-double petal count, large flower size, and lavender flower color, achieved through asexual propagation and successful reproduction in controlled environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional rose cultivars are used, then they can be grown in landscapes and gardens, but they lack uniform growth and flowering, abundant attractive foliage, and resistance to diseases
Solution Approach 1:
The patent applies parameter changes by selectively breeding roses to modify genetic parameters that control growth uniformity, flowering consistency, foliage quality, and disease resistance. Through controlled cross-pollination and selection of specific seedlings exhibiting superior traits, the cultivar achieves simultaneous improvement in multiple parameters that were previously inconsistent in conventional roses
2Productivity
If conventional rose cultivars are used, then they can be propagated and grown, but they do not exhibit vigorous growth or continuous flowering
Solution Approach 1:
The patent applies preliminary action by conducting controlled cross-pollination and selective breeding in advance to pre-establish the genetic traits for vigorous growth and continuous flowering in the cultivar before field deployment. The preliminary breeding program identified and selected seedlings with these desired characteristics, which are then propagated to ensure consistent performance

AI summary
‘KORpucoblu’ is a new and distinct variety of Rosa hybrida which is characterized by the combination of a climbing growth habit, vigorous growth, an abundance of large and very-double flowers, lavender flower color, and excellent disease resistance. The new variety propagates successfully by grafting and by stem cuttings and has shown to be uniform and stable in the resulting generations from asexual propagation.
