Solution Overview

Problem

Existing peach tree varieties lack a combination of desirable traits such as early maturity, larger fruit size, improved flavor, and enhanced storage and shipping qualities, which are essential for commercial success.

Innovation Solution

The development of a new peach tree variety, 'Summer Glory', resulting from a cross between proprietary seedling selection '358LN360' and 'Sweet Henry' Peach, exhibiting vigorous growth, regular fruiting, and characteristics like firm flesh, good flavor, and improved storage and shipping abilities, achieved through asexual reproduction using 'Nemaguard' Rootstock.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing peach tree varieties are used, then commercial cultivation is possible, but they lack a combination of desirable traits including early maturity, larger fruit size, improved flavor, and enhanced storage and shipping qualities

Engineering Contradiction:

Improvecombination of desirable traitsVSAvoidcommercial success

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent combines multiple desirable traits from different parent varieties into a single new variety 'Summer Glory'. The seed parent '358LN360' contributed early maturity and large fruit size, while the pollen parent 'Sweet Henry' Peach contributed firm flesh and good flavor. This merging of traits from multiple sources resolves the contradiction by creating a variety that simultaneously exhibits all desired characteristics for commercial success

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If asexual reproduction is used to propagate the variety, then true-to-type reproduction is achieved, but the process requires specialized rootstock grafting

Engineering Contradiction:

Improvetrue to type reproductionVSAvoidasexual propagation process

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent uses 'Nemaguard' rootstock as an intermediary in the asexual propagation process. The scion wood from the selected tree is grafted onto this standardized rootstock, which facilitates reliable propagation while maintaining true-to-type reproduction of the desired traits. This intermediary rootstock system resolves the contradiction by making the propagation process more standardized and reliable

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A new and distinct variety of peach tree (Prunus persica). 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 large size fruit.3. Clingstone fruit with firm, yellow flesh.4. Fruit with very good flavor and eating quality.5. Fruit having an attractive dark red skin color.
