Fire Gem Peach Tree Breeding for Firm Flesh and Red Skin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peach tree varieties lack a combination of firm flesh, attractive dark red skin color, and optimal maturity, as well as consistent productivity and disease resistance, which are desirable traits for commercial orchards.
Innovation Solution
The development of a new peach tree variety, 'Fire Gem', derived from the cross between 'Vista' and '7HB287' peach seedlings, budded onto 'Nemaguard' Rootstock, exhibiting vigorous growth, regular fruiting, and improved fruit characteristics such as firmness, skin color, and maturity, while maintaining hardiness and disease resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing peach tree varieties are cultivated, then they produce fruit, but the flesh is soft and skin color is not attractively dark red
Solution Approach 1:
The patent applies parameter changes by developing a new peach variety with fundamentally different fruit characteristics - specifically firmer flesh and darker red skin color - through selective breeding and genetic selection, thereby changing the inherent parameters of the fruit to meet desired quality standards
Solution Approach 2:
The patent uses asexual reproduction methods including budding and grafting to create exact genetic copies of the selected superior peach tree, ensuring that all replicated trees produce fruit with the same desirable firmness and skin color characteristics, thus achieving consistency
2Duration of action of moving object
If existing peach tree varieties are cultivated, then they produce fruit, but the maturity timing is not optimal
Solution Approach 1:
The patent changes the temporal parameter of fruit maturity by developing a variety that matures at an optimal time through selective breeding, allowing the fruit to reach peak quality at a desired point in the growing season while maintaining regular annual production
3Reliability
If existing peach tree varieties are cultivated, then they grow, but they lack disease resistance and hardiness
Solution Approach 1:
The patent uses budding and grafting techniques to replicate the genetic makeup of a selected peach tree that exhibits disease resistance and hardiness, ensuring that all propagated trees inherit these protective traits and show reduced susceptibility to diseases
Solution Approach 2:
The patent employs rootstock grafting where a disease-resistant rootstock is combined with the desired scion variety, using the rootstock as a protective foundation that provides long-term disease resistance and hardiness to the grafted tree
4Shape
If existing peach tree varieties are cultivated, then they produce fruit, but the skin color is not uniformly dark red
Solution Approach 1:
The patent uses asexual reproduction methods to create genetic copies of a selected peach tree that exhibits uniform dark red skin color, ensuring that all replicated trees produce fruit with consistent and uniform coloration throughout
Solution Approach 2:
The patent changes the color parameter of the fruit skin by selecting and propagating a variety with genetically determined uniform dark red pigmentation, achieving consistent color appearance across all fruits and trees

AI summary
A new and distinct variety of peach 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. Vigorous, upright tree growth.2. Being a regular and productive bearer of large size fruit.3. Fruit with a high degree of attractive dark red skin color.4. Firm, yellow flesh with good flavor and eating quality.5. Fruit being relatively uniform in size throughout the tree.
