NJF17 Peach Tree Flat Fruit Shape and Flavor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current peach tree varieties lack a unique combination of flat fruit shape, sweet and spicy flavor, and non-melting flesh texture, which are desirable characteristics for consumers.
Innovation Solution
The development of the 'NJF17' peach tree variety, resulting from crossing 'A43-143-782081' and 'D33-1-86227', exhibits flat fruit shape, bright green-yellow to yellow ground color, sweet and spicy flavor, non-melting flesh, and firm texture, which are maintained through asexual reproduction on the 'Lovell' rootstock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional peach varieties are used, then they have round fruit shape and mild flavor, but they lack flat fruit shape and sweet spicy flavor combination
Solution Approach 1:
The patent applies parameter changes by crossing two different peach varieties ('A43-143-782081' and 'D33-1-86227') to create a new variety with modified genetic parameters. This results in NJF17 having both flat fruit shape (from one parent) and sweet spicy flavor (from the other parent), simultaneously improving both shape and flavor profile parameters that were previously separate in conventional varieties.
2Ease of operation
If peach varieties with desirable flavor are selected, then they have sweet spicy flavor, but they lack nonmelting flesh texture and firm texture
Solution Approach 1:
Through controlled crossing of parent varieties, the patent changes the genetic parameters controlling flesh texture and flavor. The NJF17 variety inherits genes for nonmelting flesh texture and sweet spicy flavor simultaneously, resolving the contradiction between flavor quality and flesh strength by modifying the underlying genetic parameters.
3Duration of action of stationary object
If peach varieties with good keeping quality are developed, then they have firm texture, but they lack flat fruit shape
Solution Approach 1:
The patent merges desirable traits from two different parent varieties into a single NJF17 variety. It combines the flat fruit shape from one parent with the firm nonmelting flesh texture and good keeping quality from the other parent, simultaneously achieving both shape modification and improved keeping quality that were previously contradictory in conventional varieties.

AI summary
A new and distinct peach variety of Prunus persica named ‘NJF17’ is described. This variety is distinguished from other peach varieties by its unique combination of non-showy, light pink flowers, flat fruit that ripen in early mid-season, bright green-yellow to yellow fruit that are devoid of over color, clingstone fruit with a juicy, nonmelting texture and sweet, spicy flavor, and firm fruit that retain their firmness well.
