Sangria Red-2 Interspecific Prunus Tree Trait Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interspecific and apricot tree varieties lack a cultivar with a combination of desirable traits such as vigorous growth, regular fruit production, attractive reddish-purple skin color, firm red flesh, and good handling and shipping ability, which are not adequately met by existing varieties like 'Bella Jewel', '76MA153', and 'Flavorosa'.
Innovation Solution
The development of a new interspecific tree variety, 'Sangria Red-2', resulting from a cross between 'Bella Jewel' and '76MA153', exhibiting vigorous growth, regular fruit production, and medium-sized clingstone fruit with reddish-purple skin, firm red flesh, and improved maturity dates, budded onto 'Nemaguard' Rootstock for accelerated fruit production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing interspecific and apricot tree varieties are used, then cultivation is straightforward, but they lack the combination of desirable traits including vigorous growth, regular fruit production, attractive reddish-purple skin color, firm red flesh, and good handling and shipping ability
Solution Approach 1:
The patent combines multiple desirable traits from different parent varieties into a single new variety 'Sangria Red-2'. The cross between 'Bella Jewel' Interspecific and intersspecific seedling selection '76MA153' merges vigorous growth habit, regular fruit production, attractive reddish-purple skin color, firm red flesh, and good handling/shipping ability into one unified cultivar that consistently expresses all these traits together.
2Reliability
If asexual reproduction is performed to propagate the variety, then true-to-type reproduction is achieved, but time is required for propagation and orchard establishment
Solution Approach 1:
The patent performs preliminary asexual reproduction through budding in 2014 to establish cloned trees before commercial deployment. This preliminary propagation creates a foundation orchard of true-to-type trees that can be evaluated and then used for further commercial propagation, reducing the overall time required for variety establishment and ensuring trait fidelity from the start.
3Reliability
If fruit maturity is delayed to improve quality characteristics, then eating quality and handling ability are enhanced, but the harvesting window is pushed later in the season
Solution Approach 1:
The patent achieves improved fruit quality by changing the maturity parameter - the fruit matures approximately 21 days later than 'Bella Jewel' Intersspecific, 48 days later than pollen parent '76MA153', and 4 days later than commercial variety 'Flavorosa' Intersspecific. This delayed maturity allows the fruit to develop firm red flesh, attractive reddish-purple skin color, and good eating quality with excellent handling and shipping ability, demonstrating that later maturity can be advantageous for quality development.

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 having a vigorous, upright growth habit.2. Tree being a regular and productive bearer of medium size, red flesh fruit.3. Fruit with a high degree of attractive reddish-purple skin color.4. Fruit with good flavor and eating quality.5. Fruit with good storage and shipping ability.
