Interspecific Tree Variety for Large Fruit and Storage Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interspecific tree varieties face limitations in fruit size, maturity, chilling requirements, and storage quality, with 'Escort' Interspecific and proprietary seedlings exhibiting variations in these characteristics.
Innovation Solution
A new interspecific tree variety (Prunus armeniaca×Prunus salicina)×(Prunus armeniaca×Prunus persica) is developed through asexual reproduction using 'Nemaguard' Rootstock, combining desirable traits such as vigorous growth, large fruit size, firm flesh, and reduced chilling requirements, resulting in improved fruit quality and storage capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If existing intersific tree varieties are used, then fruit production is achieved, but fruit size is limited and storage quality is insufficient
Solution Approach 1:
The patent applies parameter changes by developing a new interspecific tree variety with modified genetic parameters that result in larger fruit size (average weight 173.2 grams versus smaller commercial varieties) while simultaneously improving storage quality through reduced winter chilling requirements (750 hours versus higher requirements of existing varieties), allowing the fruit to maintain firmness and eating quality during storage and shipping
Solution Approach 2:
The patent employs composite materials principle by creating an interspecific tree variety that combines genetic traits from multiple Prunus species (P. armeniaca, P. salicina, and P. persica) to achieve a composite phenotype that exhibits both larger fruit size and improved storage capabilities, merging desirable characteristics from different parental lines into a single superior variety
2Loss of time
If early maturing varieties are selected, then fruit production timing is advanced, but chilling requirements increase
Solution Approach 1:
The patent applies parameter changes by establishing a new variety with a shifted maturity parameter that is approximately 30 days later than commercial variety 'Escort' Intersspecific, while simultaneously reducing the winter chilling requirement parameter to 750 hours, creating a favorable combination of later maturity and lower chilling needs that optimizes both timing and energy requirements
3Quantity of substance
If fruit size is increased, then yield is improved, but storage and shipping quality may deteriorate
Solution Approach 1:
The patent applies parameter changes by developing a variety with increased fruit size (average weight 173.2 grams, larger than existing varieties) while simultaneously modifying the flesh firmness parameter to maintain firm texture, and improving storage quality parameters to prevent breakdown during shipping, thus achieving both high yield and maintained quality through coordinated parameter optimization

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, upright growth habit.2. Tree with heavy and regular production of large size fruit.3. Fruit with good storage and shipping quality.4. Fruit with good flavor and eating quality.5. Fruit with an attractive orange skin color.
