Sucherry3 Cherry Hybrid Early Ripening Large Fruit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new and distinct variety of cherry that combines early ripening, large fruit size, dark red flesh, sweet flavor, and firm texture, while also being adaptable to specific chilling requirements and differing from existing cherry varieties in terms of ripening time and fruit characteristics.
Innovation Solution
The development of the cherry variety 'Sucherry3' through hybridization, characterized by early ripening, large fruit size, dark red flesh, sweet flavor, and firm texture, with a chilling requirement of 650 chill units, distinguished from other cherry varieties by its unique ripening times, fruit weight, and Brix:Acid ratio, achieved through asexual propagation by dormant grafting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If early ripening is achieved through hybridization, then harvest time is advanced, but fruit size and quality may be compromised
Solution Approach 1:
The patent combines early ripening traits from the seed parent 'Cherry Seedling 1' with large fruit size and quality traits from the pollen parent 'CherryBulk12' (including 'Burlat', 'Sucherryone', and other varieties) through controlled hybridization. The resulting 'Sucherry3' variety integrates these complementary characteristics, achieving both early harvest (about 5 days earlier than seed parent) and large fruit size (8.0g average weight).
Solution Approach 2:
The patent utilizes controlled pollination and hybridization to change the genetic parameters of the cherry variety, resulting in a new variety with distinct characteristics. The 'Sucherry3' variety has been characterized by specific parameter changes including earlier bloom (2 days earlier than seed parent), earlier harvest (about 5 days earlier), higher Brix (19% vs 17%), and different chilling requirement (650 vs 800 chill units).
2Weight of moving object
If fruit size is increased through selection, then yield per tree improves, but ripening time may be delayed
Solution Approach 1:
The patent merges the large fruit size trait (8.0g average weight) with early ripening trait through the hybridization of selected parents. The pollen parent 'CherryBulk12' contributed genes for large fruit size while the seed parent 'Cherry Seedling 1' contributed early ripening genes, resulting in a variety that achieves both characteristics simultaneously rather than sequentially.
3Reliability
If sweet flavor and firm texture are achieved, then eating quality improves, but chilling requirement may increase
Solution Approach 1:
The patent achieves a reduction in chilling requirement from 800 chill units (seed parent and many pollen parents) to 650 chill units for 'Sucherry3'. This parameter change was achieved through hybridization while maintaining high eating quality characterized by sweet flavor (19% Brix), firm texture, and dark red flesh color. The variety maintains reliability for commercial production with lower chilling requirements.
4Stability of the object's composition
If asexual propagation is used to maintain variety characteristics, then variety fidelity is improved, but propagation complexity increases
Solution Approach 1:
The patent uses asexual propagation methods including dormant grafting and tissue culture to create copies of the 'Sucherry3' variety that faithfully reproduce its distinctive characteristics. These copying methods ensure that the cloned plants maintain the same early ripening time, large fruit size, sweet flavor, and firm texture as the parent variety, while the tissue culture method provides a more efficient and less complex propagation approach compared to traditional grafting.
