Golden Parsi Apple Tree Blush Retention and Russet Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a novel apple tree variety that exhibits distinguishability, homogeneity, and stability, as existing varieties like 'Golden Clone B' lack specific characteristics such as blush retention, russet patterns, and propagation consistency.
Innovation Solution
A naturally occurring tree mutation of 'Golden Clone B' has been identified and propagated as 'Golden Parsi', which retains a blush color, has low russet, and maintains its distinctive traits through asexual production, ensuring 100% variety originality and true-to-type reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a naturally occurring tree mutation is selected and propagated, then distinguishability and stability of the variety is improved, but the complexity of variety identification and propagation verification increases
Solution Approach 1:
The patent applies self-service by using the naturally occurring mutation itself as the basis for variety identification and propagation. The unique characteristics of the 'Golden Parsi' mutation (blush color, low russet, crown shape) serve as inherent markers that automatically distinguish this variety from others without requiring external verification systems or complex identification mechanisms.
Solution Approach 2:
The patent utilizes color changes as a key distinguishing feature. The 'Golden Parsi' variety exhibits a specific blush color pattern and low russet characteristics that visually differentiate it from the parental 'Golden Clone B' variety. These color variations serve as natural identifiers that simplify variety recognition and verification in commercial plantings.
2Manufacturing precision
If asexual propagation is used to maintain variety originality, then homogeneity and uniformity of the variety is improved, but the time and resources required for propagation increase
Solution Approach 1:
The patent applies copying through asexual propagation methods that create exact genetic replicas of the 'Golden Parsi' variety. By using vegetative propagation techniques, the unique mutation characteristics are precisely copied from the original mutant tree to successive generations, ensuring 100% variety originality and true-to-type reproduction without the variability introduced by sexual reproduction.
Solution Approach 2:
The patent utilizes parameter changes in the propagation process to optimize both consistency and efficiency. By controlling specific propagation parameters (such as budding techniques, rooting conditions, and selection criteria), the patent achieves high propagation consistency while minimizing the time and resources required compared to traditional propagation methods.
3Reliability
If the blush characteristic is enhanced and retained, then the distinguishability of the variety is improved, but the susceptibility to environmental factors affecting color retention increases
Solution Approach 1:
The patent applies inversion by selecting for low russet characteristics rather than high russet. The 'Golden Parsi' variety exhibits minimal russeting, which creates a clean background that allows the blush color to stand out more prominently and remain stable. This inverted approach (minimizing one pigment while maximizing another) enhances distinguishability while reducing environmental sensitivity.
Solution Approach 2:
The patent utilizes composite characteristics in the fruit skin composition. The 'Golden Parsi' variety combines specific pigment compositions (blush anthocyanins with minimal russet tannins) that create a stable, distinguishable color pattern. This composite pigment structure is more resistant to environmental degradation than single-pigment varieties, maintaining color consistency through storage and varying conditions.

AI summary
The present invention relates to a variety of an apple tree obtained by branch mutation and by selection of the variety ‘Golden Clone B’. The present invention variety ‘Golden Parsi’ exhibits an appropriate distinguishability, homogeneity, uniformity, and stability. The vigor of the tree is medium. The tree type is ramified. The habit of the apple tree is spreading. The pubescence on an upper half of a shoot is weak or similar to the pubescence in ‘Golden Delicious’. The thickness as measured by the diameter at the center is medium or similar to the thickness in ‘Jonagold’ for a one year old shoot. The number of lenticels is many for a one year old shoot. The predominant color of a flower is dark pink in a balloon stage. An overcolor appears early in season with a brown-red color. The overcolor disappears almost totally, and toward harvest increases and gets red. The overcolor remains red even after months of storage.
