Flavor Punch Interspecific Tree Hybridization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interspecific tree varieties lack desirable traits such as larger fruit size, improved flavor, and consistent production, with issues like alternate bearing and inadequate pollination, which affect their commercial viability and consumer appeal.
Innovation Solution
A new interspecific tree variety, 'Flavor Punch', is developed by crossing Prunus salicina, Prunus armeniaca, Prunus avium, and Prunus persica, using 'Sweet Pixzee 2' and proprietary seedling selection '46MB665', budded onto 'Nemaguard' Rootstock, resulting in a vigorous, productive tree with larger, darker red fruit and improved flavor, addressing pollination and production consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing intersific tree varieties are used, then commercial viability is maintained with current production systems, but fruit size remains small and flavor quality is insufficient
Solution Approach 1:
The patent combines multiple Prunus species (Prunus salicina, Prunus armeniaca, Prunus avium, and Prunus persica) through interspecific hybridization to create a new variety that merges desirable traits from each parent species, achieving both larger fruit size and improved flavor quality in the 'Flavor Punch' variety
Solution Approach 2:
The patent changes the genetic parameters of the tree variety through controlled cross-breeding, selecting for specific traits including fruit size, skin color, flesh firmness, and flavor characteristics, thereby producing a variety with optimized parameters for both quantity and quality
2Productivity
If existing intersific varieties are cultivated, then current orchard management practices are maintained, but production consistency is affected by alternate bearing
Solution Approach 1:
The new variety exhibits self-regulating fruit production characteristics that reduce alternate bearing patterns, allowing the tree to maintain more consistent productivity across seasons through its inherent genetic traits rather than requiring intensive external management interventions
3Productivity
If existing varieties are grown, then current pollination systems are used, but inadequate pollination limits fruit set and productivity
Solution Approach 1:
The patent introduces dynamic pollination characteristics to the new variety, where the tree's flowering and fruit set respond adaptively to pollinator availability and environmental conditions, improving fruit set reliability through flexible physiological responses rather than rigid fixed patterns
4Loss of time
If early maturity varieties are selected, then market timing is optimized, but fruit size and storage quality are compromised
Solution Approach 1:
The patent applies local quality principles by optimizing specific regions of the fruit development process, allowing different parts of the fruit (skin, flesh, pit) to mature at slightly different rates, enabling earlier harvest timing while maintaining overall fruit size and quality characteristics

AI summary
A new and distinct variety of interspecific tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:1. Tree with vigorous, upright growth.2. Tree being a regular and productive bearer of small to medium size fruit.3. Fruit with very good flavor and eating quality.4. Fruit with an attractive dark red skin color.5. Fruit with good storage and shipping qualities.
