Ranunculus Cultivar ABULANJI Breeding for Orange Flower Traits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new Ranunculus cultivar that exhibits distinct and stable characteristics such as vibrant orange flower color, larger flower size, and transformed androecium to petals, which are not consistently achieved in existing varieties under varying environmental conditions.
Innovation Solution
The cultivar 'ABULANJI' is developed through a planned breeding program, combining the seed parent Ranunculus 'A6-07/1' and pollen parent Ranunculus A11-07.1', resulting in a unique phenotype with deeper orange flower color, larger flower size, and transformed androecium to petals, which is stable across multiple generations and environmental conditions.

Engineering Contradiction Analysis
1Quantity of substance
If existing Ranunculus varieties are used, then basic flowering characteristics are maintained, but flower color vibrancy, flower size, and petal transformation are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic parameters that produce deeper orange flower color (near Greyed-Yellow N163C), larger flower size (8-10 cm diameter), and transformed androecium to petals. These parameter changes are stabilized through controlled crossing between specific parent plants and subsequent selection of offspring that consistently express these traits across generations and environmental conditions.
2Shape
If conventional breeding methods are used, then basic variety traits are preserved, but unique characteristics like transformed androecium to petals and denser foliage are not achieved
Solution Approach 1:
The breeding program is segmented into distinct phases: (1) initial crossing of selected parent plants, (2) evaluation of F1 hybrids for desired traits, (3) selection of superior individuals, and (4) propagation through tissue culture. This segmentation allows systematic achievement of complex traits like denser foliage arrangement and transformed androecium without overwhelming complexity at each step.
Solution Approach 2:
Tissue culture serves as an intermediary method to propagate selected plants with desired characteristics (deeper orange color, larger size, transformed androecium, denser foliage) uniformly. This intermediary propagation technique ensures that the complex traits developed through breeding are consistently reproduced without requiring repeated complex crossing operations.

AI summary
A new and distinct Ranunculus cultivar named ‘ABULANJI’ is disclosed, characterized by a vibrant orange flower color. Plants produce an above average quantity of flowers of high quality throughout the flowering season. Flower size produced remains large throughout the flowering season. The new variety is a Ranunculus, normally produced as a cut flower and potentially useful as an ornamental plant.
