Summer Princess Peach Tree Hybridization for Shipping Durability
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, vigor, self-fertility, and specific fruit characteristics like yellow flesh and bitter kernel, while being adaptable to California's climate and suitable for long-distance shipping.
Innovation Solution
The 'Summer Princess' peach tree variety is developed through hybridization, characterized by its large size, vigorous growth, self-fertility, and specific fruit traits like yellow flesh and bitter kernel, requiring 600 chilling hours, and exhibiting heat and drought tolerance, making it suitable for commercial orchards and shipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hybridization is used to combine desirable traits from different parent varieties, then the fruit quality and tree characteristics are improved, but the breeding process time and complexity increase
Solution Approach 1:
The patent performs preliminary selection of parent varieties with desired traits (August Pearl nectarine for red skin and clingstone特性, yellow flesh peach for flesh color) before hybridization. This preliminary preparation ensures that the hybridization process directly produces offspring with the target characteristics, reducing the time needed for subsequent selection and breeding iterations.
2Productivity
If the tree is made larger and more vigorous for higher productivity, then the fruit yield increases, but the tree requires more resources and space
Solution Approach 1:
The patent achieves high productivity by optimizing specific biological parameters of the tree including chilling hour requirements (600 hours), blooming timing (mid to late season), and self-fruitfulness. These parameter optimizations allow the tree to maintain vigorous growth and high yield while being adapted to California's specific climatic conditions, effectively utilizing available resources.
3Volume of stationary object
If the fruit is made larger for better market quality, then the commercial value increases, but the shipping durability may be reduced
Solution Approach 1:
The patent creates a composite of desirable traits by hybridizing August Pearl nectarine (providing red skin color and clingstone特性) with yellow flesh peach (providing flesh color and flavor). The resulting fruit combines large size (3-4 inches diameter) with firm texture and thick skin, creating a composite structure that maintains both market quality and shipping durability through the synergistic combination of parent variety characteristics.
4Reliability
If the tree is adapted to local climate conditions for hardiness, then the survival rate improves, but the adaptability to different regions decreases
Solution Approach 1:
The patent develops a peach variety with universal adaptability by optimizing for moderate chilling requirements (600 hours) and mid to late season blooming, which allows the tree to thrive in California's climate while maintaining potential adaptability to other regions with similar temperate conditions. The self-fruitful characteristic further enhances universality by ensuring reliable production without requiring specific pollinator varieties.

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 mid to late season and requires about 600 chilling hours. The fruit matures under the ecological conditions described in late August, with first picking on Aug. 25, 2013. The fruit is uniform, very large in size, acidic with traditional peach flavor, nearly globose in shape, clingstone in type, firm in texture, yellow in flesh color, virtually full red in skin color, and has a bitter tasting kernel.
