Self-Fertile Cherry Tree Resolving Deep Suture Defects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cherry tree varieties like 'Chelan' and 'Brooks' require cross-pollination, leading to irregular cropping and 'deep suture' issues, resulting in lower fruit quality and price, whereas 'SMS-16-CA 2014-16' is self-fertile, produces fewer 'deep suture' fruits, and has superior organoleptic qualities and larger fruit size.
Innovation Solution
The 'SMS-16-CA 2014-16' cherry tree variety is an early ripening, self-fertile selection with improved fruit size, regular cropping, and reduced 'deep suture' issues, making it more productive and commercially viable compared to 'Chelan' and 'Brooks'.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cross-pollination is required (as in 'Chelan' and 'Brooks' varieties), then genetic diversity is maintained, but cropping regularity deteriorates and deep suture issues increase
Solution Approach 1:
The cherry tree variety 'SMS-16-CA 2014-16' is self-fertile, meaning it can pollinate itself and produce fruit without requiring cross-pollination from other trees. This self-service capability eliminates the need for complex pollination management, ensures regular annual cropping, and prevents deep suture defects that occur with cross-pollination-dependent varieties.
2Productivity
If larger fruit size is produced, then market value increases, but deep suture defects increase leading to lower grading
Solution Approach 1:
The patent converts the potential harm of large fruit size (which typically develops deep suture defects) into a benefit by using self-fertile pollination. This produces large-fruited varieties (25-36mm diameter) with smooth suture lines, transforming what would normally be a quality defect into a marketable advantage.
3Productivity
If self-fertility is implemented, then cropping regularity improves, but genetic diversity may be reduced
Solution Approach 1:
The patent changes the genetic parameter of pollination requirement from cross-pollination dependent to self-fertile. This parameter change ensures regular annual cropping cycles while maintaining sufficient genetic diversity through the open pollination breeding method used to develop the variety.

AI summary
A new and distinct variety of cherry tree, which is denominated varietally as ‘SMS-16-CA 2014-16’ is described, and which produces fruit having a very large size, an early ripening time, is highly productive, and which further has symmetrically shaped fruit when grown under the ecological conditions prevailing in the states of California and Washington, and wherein the mature fruit displays little or no indentation along the suture line.
