Apple Tree PE Cultivar Early Maturity and Fruit Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new apple tree variety that exhibits early maturity, distinctive pink-red fruit color, and specific leaf and wood characteristics, which are not adequately met by existing varieties like 'Cripps Pink', 'Ruby Pink', and 'Lady in Red'.
Innovation Solution
A new apple tree cultivar 'PE' is developed, characterized by its early full pink-red color, reddish-brown wood, high leaf and young fruit anthocyanin levels, and serrate leaf blade incisions, distinguished from its parent 'Cripps Pink' and other similar varieties through asexual reproduction by bud grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If early maturity is achieved in apple variety, then harvest time is improved, but fruit color development and anthocyanin levels may be compromised
Solution Approach 1:
The patent applies parameter changes by selecting and propagating mutant trees with altered genetic parameters that enable early maturity while maintaining enhanced fruit color development and anthocyanin levels, thus resolving the contradiction between harvest time and color development
2Illumination intensity
If very large levels of leaf anthocyanin and high levels of young fruit anthocyanin are achieved, then fruit color intensity is improved, but genetic stability across generations may be compromised
Solution Approach 1:
The patent applies self-service by using asexual reproduction through bud grafting, where the selected mutant tree propagates itself to produce genetically identical offspring that maintain the desired anthocyanin levels and fruit color intensity, ensuring both high color intensity and genetic stability
Solution Approach 2:
The patent applies copying by creating exact genetic copies of the mutant tree through asexual reproduction, preserving the specific genetic traits for high anthocyanin production and intense fruit color across multiple generations without genetic variation
3Shape
If distinctive characteristics such as reddish-brown wood color and serrate leaf blade incisions are achieved, then variety differentiation is improved, but adaptability to different growing conditions may be compromised
Solution Approach 1:
The patent applies local quality by selecting for specific localized traits (serrate leaf blade incisions, reddish-brown wood color) that provide variety differentiation while the overall genetic background maintains adaptability to different growing conditions through the established 'Cripps Pink' base

AI summary
A new and distinct apple tree (Malus domestica) named ‘PE’. ‘PE’ is a spontaneous limb mutation of ‘Cripps Pink’ and is distinguished by its very early full pink-red color over the entire fruit surface, even in shaded areas of the limb. ‘PE’ is also distinguished from its parent by its early maturity, reddish-brown wood color on the sunny side, very large level of leaf anthocyanin, high levels of young fruit anthocyanin, and high intensity of Pink-Red overcolor. The pattern of overcolor is solid blush. Leaf blade incisions are serrate type 1, there are fewer lenticels on one-year-old wood, and leaf blade length and width are also smaller than for the parent.
