Crimson Carson Interspecific Tree Early Maturity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interspecific plum and plumcot varieties face challenges in early maturity, chilling requirements, and fruit quality, with limited options for varieties that combine desirable traits like vigorous growth, regular bearing, and good shipping and storage qualities.
Innovation Solution
A new interspecific tree variety, 'Crimson Carson', derived from a combination of Prunus salicina and Prunus armeniaca, exhibiting vigorous growth, regular bearing, and improved fruit characteristics such as red skin, firm flesh, and earlier maturity, achieved through asexual reproduction using 'Nemaguard' Rootstock, which addresses the limitations of existing varieties by offering approximately 7 days earlier maturity and reduced chilling requirements compared to 'Flavor Royale'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If existing intersific plum and plumcot varieties are cultivated, then they provide fruit production, but they have late maturity and high chilling requirements
Solution Approach 1:
The patent applies parameter changes by developing a new interspecific variety 'Crimson Carson' that fundamentally alters the chilling requirement parameter from 700-800 hours (parent stock) to approximately 600 hours, while simultaneously changing the maturity time parameter to achieve 7 days earlier maturity compared to 'Flavor Royale'. This variety represents a genetic parameter change that resolves the contradiction between early maturity and reduced chilling requirements.
2Productivity
If existing intersific varieties are cultivated, then they produce fruit, but the fruit lacks firm flesh and good shipping/storage quality
Solution Approach 1:
The patent applies local quality by developing fruit with specifically improved local characteristics - firm flesh texture and red skin color - while maintaining overall fruit production. The 'Crimson Carson' variety exhibits localized quality improvements in the fruit flesh (firmness for shipping/storage) and skin (attractive red color), distinguishing it from parent varieties that lacked these specific local qualities.
3Productivity
If existing intersific varieties are cultivated, then they provide fruit production, but they show irregular bearing patterns
Solution Approach 1:
The patent applies self-service by developing a variety that inherently provides regular annual bearing without requiring complex management interventions. The 'Crimson Carson' variety exhibits self-regulating bearing patterns that eliminate the need for sophisticated thinning programs or alternate bearing management, allowing the tree to naturally produce consistent crops year after year with standard cultural practices.

AI summary
A new and distinct variety of interspecific tree. The following features of the tree and its fruit are characterized with the tree budded on ‘Nemaguard’ Rootstock (non-patented), grown on Handford sandy loam soil with Storie Index rating 95, in USDA Hardiness Zone 9, near Modesto, Calif., with standard commercial fruit growing practices, such as pruning, thinning, spraying, irrigation and fertilization. Its novelty consist of the following combination of desirable features:1. Tree with vigorous, upright growth.2. Heavy and regular production of medium size fruit.3. Fruit with attractive red skin color.4. Fruit with very good flavor and eating quality.
