Ice Queen Peach Tree Early Maturity and Shipping Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new variety of peach tree that combines desirable traits such as early maturity, sweeter flavor, and improved shipping quality, while maintaining hardiness and productivity, which existing peach varieties have not effectively addressed.
Innovation Solution
The 'Ice Queen' peach tree is developed through a first-generation cross between 'Snow Princess' peach and an unnamed yellow flesh nectarine, resulting in a self-fertile, vigorous tree producing white flesh freestone peaches that mature seven days earlier and have a balanced flavor, suitable for commercial orchards with specific chilling requirements and climatic adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If existing peach varieties are used, then traditional flavor and texture are maintained, but maturity time is later and shipping quality is insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and combining specific genetic parameters from parent varieties to create a new peach variety with improved maturity time and shipping quality. The inventor evaluated multiple parameters including flesh color, flavor balance, firmness, and maturity date, then selected combinations that achieved early maturity (July 20-30) while maintaining firm texture and good shipping quality, directly resolving the contradiction between faster maturity and reliable shipping performance
2Quantity of substance
If peach varieties are hybridized to improve flavor and maturity, then fruit quality is enhanced, but tree hardiness and productivity may be compromised
Solution Approach 1:
The patent applies segmentation by systematically evaluating and selecting specific desirable traits from multiple parent varieties rather than creating entirely new hybrids. The inventor segmented the selection process into evaluating individual traits (flesh color, flavor, firmness, maturity) and then combining them through controlled cross-pollination, ensuring that each trait contribution was deliberate and maintained tree hardiness and productivity while enhancing fruit quality
3Loss of time
If peach varieties are developed for early maturity and sweet flavor, then consumer appeal is improved, but acid balance and overall flavor complexity may be reduced
Solution Approach 1:
The patent applies local quality by achieving early maturity and sweet flavor in specific local areas of the fruit while maintaining appropriate acid balance in other areas. The selected variety exhibits concentrated sweetness and early maturity characteristics in the flesh, while the skin and overall flavor profile maintain balanced acidity, creating a harmonious flavor profile that satisfies both early maturity demand and flavor complexity requirements

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 the last half of July, with first picking on Jul. 20, 2012. The fruit is uniform, large in size, globose in shape, freestone in type, firm and melting in texture, white in flesh color, almost full red in skin color, and a tasty balance of light acid and sugar in flavor.
