Nyssa Plant The James Cultivar Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct cultivar of Nyssa sylvatica that exhibits unique characteristics such as vigorous growth, dense foliage, and specific leaf and petiole colors, which are not met by existing cultivars like 'Wildfire', 'Tupelo Power', and 'Forum', and are stable across varying environmental conditions.
Innovation Solution
The new cultivar 'The James' is a naturally occurring branch mutation of Nyssa sylvatica 'Wildfire' with a broadly ovate tree form, upswept branching habit, glossy dark green leaves that turn orangish red in autumn, and red-colored leaf petioles, propagated through chip budding, demonstrating enhanced vigor and density compared to other cultivars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If existing cultivars like 'Wildfire' are used, then they provide green foliage, but they lack the specific combination of vigorous growth, dense foliage, and red petioles that 'The James' exhibits
Solution Approach 1:
The patent identifies and selects for specific phenotypic parameters including red petiole color, dark green leaf color, and vigorous growth habit. By selecting for these specific parameter combinations through asexual reproduction, the cultivar achieves stable expression of dense foliage and distinctive coloring that differentiates it from parent and other cultivars.
2Stability of the object's composition
If asexual reproduction is used to maintain stability, then genotype remains constant, but environmental variations may still affect phenotype expression
Solution Approach 1:
The patent performs preliminary selection of the mutant branch exhibiting desired traits before propagation. By selecting the specific mutation that displays red petioles, dark green leaves, and vigorous growth, and then propagating through chip budding, the cultivar establishes stable genetic expression of these traits that will be reliably reproduced across generations despite environmental variations.
3Shape
If broader branching habit is selected, then tree form becomes more ornamental, but growth vigor may be reduced
Solution Approach 1:
The patent selects for a specific local quality - the broadly ovate tree form with upswept branching - that occurs in conjunction with vigorous growth in the mutant branch. This local structural characteristic is inherited together with the growth vigor through asexual propagation, creating a cultivar that simultaneously achieves ornamental form and vigorous productivity that distinguishes it from other cultivars.

AI summary
A new and distinct cultivar of Nyssa tree named ‘The James’, characterized by its broadly ovate tree form with upswept branching habit; vigorous growth habit; freely branching habit with numerous lateral branches providing a full and densely foliated appearance; large glossy dark green-colored leaves that become orangish red in color during the autumn; and red-colored leaf petioles.
