Bella Rose Interspecific Tree Early Maturity and Compact Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plum and apricot tree varieties lack desirable fruit and tree characteristics such as early maturity, attractive skin color, and balanced flavor, as well as efficient asexual reproduction methods for consistent propagation.
Innovation Solution
The development of an interspecific tree variety, 'Bella Rose', resulting from crosses between Prunus salicina, Prunus armeniaca, and Prunus persica, which exhibits earlier maturity, attractive red skin, and good flavor, achieved through asexual reproduction using 'Nemaguard' Rootstock, ensuring consistent fruit and tree characteristics across propagations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional plum and apricot varieties are used, then tree stability and fruit production are maintained, but fruit maturity is delayed and tree size becomes excessive
Solution Approach 1:
The patent applies parameter changes by selectively combining genetic parameters from different species (Prunus salicina, Prunus armeniaca, Prunus persica) to create an interspecific hybrid that matures 30 days earlier than traditional varieties while maintaining manageable tree size through controlled breeding parameters
Solution Approach 2:
The breeding program segments the development process into controlled crosses between specific parent varieties (288LF475 and 57EF372), allowing independent optimization of maturity time and tree size parameters through systematic evaluation of offspring generations
2Reliability
If asexual reproduction methods are used, then consistent propagation is achieved, but reproduction efficiency is reduced
Solution Approach 1:
The patent employs asexual reproduction through budding and grafting to create genetic copies of the selected parent trees, ensuring that the desirable characteristics (early maturity, red skin, good flavor) are consistently transmitted to offspring while maintaining the same genetic makeup across propagations
3Manufacturing precision
If fruit flavor and quality are prioritized, then eating quality improves, but fruit size and production efficiency are reduced
Solution Approach 1:
The patent applies local quality by selecting and propagating specific regions of the fruit (such as the red skin portions and flavor-concentrated areas) while maintaining overall fruit size and production efficiency through controlled pollination and cultivation practices that optimize both quality and quantity

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. Heavy and regular production of medium size fruit.2. Fruit with good flavor and eating quality.3. Fruit with an attractive red skin color.4. The tree being approximately ½ the height and width of standard commercial fruit trees.5. Fruit with good storage and shelf life.
