Suapri15 Apricot Tree Hybridization and Propagation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of apricot tree that offers improved fruit characteristics such as ripening time, skin texture, sweetness, and aroma, while maintaining consistency through asexual propagation methods like grafting and cuttings.
Innovation Solution
The development of the apricot tree variety 'Suapri15' through hybridization, characterized by medium-sized fruit with smooth skin, dark orange flesh, firm and sweet flavor, and weak stone adherence, which ripens midseason and exhibits higher brix and brix:acid ratios compared to existing varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hybridization is used to develop new apricot variety, then fruit characteristics such as sweetness and aroma are improved, but the complexity of the breeding process increases
Solution Approach 1:
The patent applies preliminary action by performing hybridization between specifically selected parent varieties ('Robada' and an unknown pollen parent) before propagation. The breeding process was conducted in advance with controlled cross-pollination in February 2008, followed by sowing in February 2009 and identification in May 2011, ensuring the desired fruit characteristics were established before asexual propagation began in February 2012.
2Stability of the object's composition
If asexual propagation is used to maintain variety characteristics, then consistency of fruit quality is maintained, but the time required for propagation increases
Solution Approach 1:
The patent applies dynamics by using multiple asexual propagation methods (dormant grafting, cuttings) that can be performed at different times and under different conditions. The variety has been propagated successively through these dynamic methods, allowing flexibility in timing while maintaining genetic consistency of the Suapri15 variety characteristics.
3Productivity
If fruit ripening is accelerated to meet market demands, then productivity is improved, but fruit quality such as sweetness and aroma may deteriorate
Solution Approach 1:
The patent applies parameter changes by achieving a Brix:Acid ratio of 23 through selective hybridization, which is higher than the parent variety 'Robada' (ratio of 19). This parameter optimization allows the fruit to ripen midseason with maintained sweetness (18% Brix) and aroma quality, resolving the contradiction between ripening speed and fruit quality.
4Shape
If skin texture is made smoother for consumer preference, then marketability is improved, but the fruit may become more susceptible to damage during shipping
Solution Approach 1:
The patent applies local quality by achieving smooth skin texture on the fruit surface while maintaining overall fruit firmness. The Suapri15 variety exhibits smooth skin compared to the bumpy skin of parent variety 'Robada', and this localized improvement in skin texture is maintained without compromising the firm flesh that provides shipping durability.

AI summary
A new and distinct variety of apricot tree, Prunus armeniaca ‘Suapri15’, is characterized by having fruit that is medium sized, with dark orange flesh that ripens midseason. The fruit of the new variety ‘Suapri15’ also has firm flesh, a mildly sweet flavor with abundant aroma and a stone that has very weak adherence to the flesh.
