Ice Zee Peach Tree Variety Earlier Maturity and Red Skin Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing peach tree varieties lack desirable traits such as consistent fruit production, flavor, and maturity timing, with limited options for growers seeking earlier maturity and attractive fruit color.
Innovation Solution
The development of the 'Ice Zee' peach tree variety, which is asexually reproduced using the 'Nemaguard' Rootstock, offering larger, more vigorous trees with earlier maturity, brighter red skin color, and improved flavor, and is characterized by being a regular bearer with self-fertility and good hardiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing peach tree varieties are used, then established cultivation practices can be maintained, but fruit maturity timing and flavor quality are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and propagating a peach tree variety with specifically altered maturation parameters. The 'Ice Zee' variety matures approximately 6 days earlier than its seed parent and 18 days earlier than 'Snow Bliss' Peach, while maintaining consistent bearing patterns. This temporal parameter shift resolves the contradiction by providing both reliability through regular bearing and time efficiency through earlier maturity.
2Reliability
If existing peach varieties are cultivated, then current market options are maintained, but fruit color attractiveness and flavor quality are limited
Solution Approach 1:
The patent applies local quality by enhancing specific visual attributes of the fruit while maintaining overall tree productivity. The 'Ice Zee' peach exhibits distinctly brighter red skin color and reddish-pink flesh coloration compared to parent varieties, creating localized quality improvement in the fruit appearance without compromising the reliable regular bearing pattern of the tree.
3Adaptability or versatility
If open pollinated seedlings are selected, then genetic diversity is achieved, but consistency of fruit characteristics across propagations is challenged
Solution Approach 1:
The patent applies copying by transitioning from open-pollinated seedling selection to asexual propagation through budding. Once the desirable 'Ice Zee' seedling was identified with superior traits, it was asexually propagated to create genetically identical copies, ensuring that fruit characteristics remain consistent across all propagations while the initial selection phase had utilized genetic diversity.

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. Tree with vigorous, upright growth.2. Regular and productive bearer of large size fruit.3. Fruit having a high degree of attractive red skin color.4. Fruit with very good flavor and eating quality.5. Fruit with firm flesh and good shipping quality.
