Interspecific Tree ‘Trinidad’ Resolving Fruit Size and Chilling Requirements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interspecific tree varieties face challenges in fruit size, chilling requirements, and maturity dates, with limited options for trees that combine desirable traits like large fruit size, low chilling requirements, and early maturity.
Innovation Solution
A new interspecific tree variety (Prunus armeniaca × Prunus salicina) is developed through asexual reproduction using a proprietary non-patented interspecific seedling '15MA725' and 'Leah Cot' Interspecific, exhibiting larger fruit size, reduced chilling requirements, and earlier maturity compared to existing varieties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If existing interspecific tree varieties are used, then fruit production is maintained, but fruit size is limited and chilling requirements are high
Solution Approach 1:
The patent applies parameter changes by selectively breeding and combining specific genetic parameters from different parent varieties to achieve a new variety with larger fruit size and reduced chilling requirements. The new variety 'Trinidad' combines parameters from parents to produce fruit that is larger than existing varieties while requiring fewer chilling hours, directly resolving the contradiction between fruit size and chilling requirement.
2Productivity
If existing interspecific tree varieties are used, then fruit production is maintained, but maturity date is delayed
Solution Approach 1:
The patent utilizes parameter changes in the breeding program to select and combine genetic parameters that accelerate fruit maturation. The new variety 'Trinidad' matures approximately 24 days earlier than its pollen parent and 10 days earlier than the commercial variety 'Betty-Cot', while maintaining productive fruit bearing, thus resolving the contradiction between fruit production and maturity timing.
3Stability of the object's composition
If asexual reproduction is used, then variety characteristics are preserved, but genetic diversity is reduced
Solution Approach 1:
The patent applies segmentation by using asexual reproduction methods (budding and grafting) to create multiple copies of the selected variety characteristics while maintaining the genetic integrity of the parent plant. This allows the preservation of desirable traits through clonal propagation while the breeding program itself maintains genetic diversity through controlled crosses between different parent varieties.

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 a vigorous, semi-spreading growth habit.2. Tree being a regular and productive bearer of medium to large size fruit.3. Fruit with good flavor and eating quality.4. Fruit with an orange skin color and attractive red blush.5. Fruit with good storage and shipping quality.
