Plumcandy X Interspecific Plum Tree Hybridization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of plum tree that produces fruit that is sweeter, with a unique coconut flavor, and has improved shipping and storage qualities, while being compatible with existing rootstocks and requiring cross-pollination for fruit production.
Innovation Solution
The development of the 'Plumcandy X' variety, which is an interspecific plum tree resulting from cross-pollination between a red plum tree and apricot and interspecific hybrid trees, producing fruit that is firm, medium-sized, red-skinned, white-fleshed, and semi-clingstone, with a hint of coconut flavor, and is compatible with 'Nemaguard' rootstock for asexually reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cross-pollination is used to develop new variety, then fruit flavor and sweetness are improved, but pollination requirements become more complex
Solution Approach 1:
The patent uses bee hives as intermediary agents to facilitate cross-pollination between different plum and apricot trees. The bees naturally transfer pollen between trees during their foraging activities, eliminating the need for manual pollination management while achieving the desired genetic hybridization and improved fruit characteristics.
2Reliability
If fruit size is reduced for shipping, then shipping and storage qualities are improved, but yield per tree decreases
Solution Approach 1:
The patent achieves the optimal balance between fruit size and shipping quality by changing the genetic parameters through controlled cross-pollination. The resulting 'Plumcandy X' variety produces fruits that are smaller than traditional plums (improving shipping and storage) while maintaining adequate yield through enhanced fruit set and uniform ripening characteristics inherited from the hybrid parentage.
3Stability of the object's composition
If self-unfruitful trait is introduced, then cross-pollination ensures genetic diversity, but additional pollinator trees are required
Solution Approach 1:
The patent creates a universal pollination system where the self-unfruitful 'Plumcandy X' variety can be planted alongside multiple different pollinator types (apricot and plum varieties). This multi-functionality allows the same cultivar to work with various pollinators, ensuring genetic diversity while providing flexibility in orchard design and planting arrangements.

AI summary
The present invention relates to an interspecific tree and more particularly to a new and distinct variety broadly characterized by a large size, medium vigorous, hardy, and very productive tree. Being self-unfruitful, the present variety requires cross pollination from an apricot, interspecific, or plum that blooms during the mid season. The fruit matures under the ecological conditions described during early September, with first picking on Sep. 8, 2011. The fruit is uniformly medium in size, full red in skin color, semi-clingstone in type, globose in shape, yellowish white in flesh color, firm in texture, and mildly sweet with a hint of coconut in flavor.
