Glacier Queen Peach Tree Breeding for Firm Freestone Fruit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of peach tree that combines desirable traits such as large size, firm texture, freestone type, and sub-acidic flavor, while differing from existing varieties in flesh color, leaf gland shape, and ripening time, to improve fruit quality and shipping efficiency.
Innovation Solution
The 'Glacier Queen' peach tree is developed through a first-generation cross between 'Snow Princess' and '3P1236', resulting in peaches that are white in flesh color, sub-acidic, and larger in size, with globose leaf glands, and requiring 450 chilling hours, which distinguishes it from other varieties like 'Snow Princess', 'Pearl Princess V', and 'Snow Duchess'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the peach variety is made larger in size, then the fruit quality and shipping efficiency are improved, but the ripening time is delayed
Solution Approach 1:
The patent changes the parameter of fruit size by crossing 'Snow Princess' with an unnamed yellow flesh freestone peach (3P1236), resulting in Glacier Queen peaches that are uniformly large and globose in shape. This parameter change achieves improved fruit quality and shipping efficiency while accepting the trade-off of delayed ripening time, which is actually beneficial for extended harvest windows.
2Strength
If the peach variety is made firm in texture, then the shipping durability is improved, but the flavor becomes less acidic
Solution Approach 1:
The patent achieves firm texture by selecting and propagating the Glacier Queen variety, which inherits firmness from its parents. The flavor characteristic is intentionally modified to be sub-acidic rather than highly acidic, representing a desirable parameter change for market preferences while maintaining shipping durability through firm tissue structure.
3Illumination intensity
If the peach variety is made white in flesh color, then the visual appeal and market value are improved, but the variety differs from traditional yellow flesh types
Solution Approach 1:
The patent produces Glacier Queen peaches with uniform white flesh color through controlled crossbreeding, achieving improved visual appeal and market value. This parameter change creates a distinct variety that differs from traditional yellow flesh peaches, expanding market diversity while maintaining high quality standards.
4Productivity
If the peach variety is made freestone in type, then the processing efficiency is improved, but the kernel becomes bitter tasting
Solution Approach 1:
The patent maintains the freestone characteristic inherited from both parents, which enables efficient processing by allowing easy removal of the pit. The bitter kernel flavor is an acceptable trade-off, as the freestone type provides significant processing advantages and the kernel bitterness does not affect the quality of the flesh portion, which is the primary commercial product.

AI summary
The present invention relates to a new and distinct variety of peach tree, Prunus persica, broadly characterized by a large size, vigorous, hardy, self-fertile, productive and regular bearing tree. The variety blooms during the early to mid season and requires about 450 chilling hours. The fruit matures under the ecological conditions described in late August, with first picking on Aug. 24, 2011. The fruit is uniform, very large in size, sub-acidic in flavor, globose in shape, freestone in type, firm and melting in texture, white in flesh color, mostly red in skin color, and good in flavor.
