Summer Cot Interspecific Tree Breeding for Consistent Fruit Production
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apricot and interspecific tree varieties face challenges in consistent fruit production, flavor, and maturity timing, with many exhibiting alternate bearing and inadequate storage and shipping qualities.
Innovation Solution
Development of a new interspecific tree variety, 'Summer Cot', resulting from a cross between '192LD95' and '381LH520', which is asexually reproduced and exhibits vigorous growth, regular fruit production, improved flavor, and extended maturity, offering larger fruit with better storage and shipping qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing apricot and interspecific tree varieties are used, then fruit production is achieved, but fruit production is inconsistent and alternate bearing occurs
Solution Approach 1:
The patent applies parameter changes by creating a new interspecific variety through controlled cross-breeding between specific parent varieties ('Patterson' apricot and '381LH520' plumcot). This genetic parameter change results in offspring with modified fruiting patterns that eliminate alternate bearing and ensure consistent annual production, directly resolving the reliability-productivity contradiction.
2Quantity of substance
If existing apricot and intersspecific tree varieties are used, then fruit is produced, but flavor is inadequate
Solution Approach 1:
The patent utilizes parameter changes through genetic breeding to transform the flavor profile of the fruit. The cross between 'Patterson' apricot (known for good flavor) and '381LH520' plumcot produces offspring with enhanced sugar content, improved acid-sugar balance, and superior overall flavor characteristics, thereby resolving the contradiction between flavor quality and eating quality.
3Duration of action of stationary object
If existing apricot and intersspecific tree varieties are used, then fruit is produced, but storage and shipping qualities are inadequate
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific fruit characteristics that enhance post-harvest performance. The new variety exhibits firmer flesh texture, better skin integrity, and improved overall structural qualities that extend storage duration and enhance shipping durability, directly resolving the contradiction between storage quality and shipping quality.
4Loss of time
If existing apricot and intersspecific tree varieties are used, then fruit is produced, but maturity timing is not extended
Solution Approach 1:
The patent utilizes parameter changes through genetic breeding to shift the maturity timeline. The cross between the parent varieties produces offspring with delayed ripening characteristics, extending the harvest season by approximately 10-15 days compared to traditional varieties, thereby resolving the contradiction between maturity timing extension and maintained fruit production.

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. Regular and productive bearer of large size fruit.2. Fruit with good flavor and eating quality.3. Fruit maturing in the late maturity season.4. Fruit with good storage and shipping quality.5. Vigorous, semi-spreading tree growth.
