IFG Cher-ten Sweet Cherry Tree Low Chill Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sweet cherry tree varieties face challenges in low chill regions due to high chilling requirements, and existing varieties like 'Brooks' and 'IFG Cher-three' have issues with fruit quality, storage, and pollen compatibility, limiting their adaptability and market potential.
Innovation Solution
The development of 'IFG Cher-ten', a sweet cherry tree with medium-low chilling requirements, producing large, dark red, firm fruits with excellent storage and shipping characteristics, and specific pollen incompatibility, allowing for better adaptability and reduced undesirable fruit forms in warm regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing sweet cherry varieties like 'Brooks' are grown in warm regions, then they can produce fruit, but they have high chilling requirements that cannot be met in low chill regions
Solution Approach 1:
The patent applies parameter changes by developing a cherry variety with modified chilling requirements. 'IFG Cher-ten' was bred to require only 400-500 chilling hours, representing a significant reduction from the 800-1000 hours required by traditional varieties like 'Brooks'. This parameter change enables the variety to thrive in low-chill regions where previous varieties failed.
2Productivity
If existing varieties are grown in high summer temperature regions, then they can produce fruit, but they produce many doubled and spurred fruits which are undesirable
Solution Approach 1:
The patent converts the harmful effect of high summer temperatures that cause doubled and spurred fruits into a benefit by selecting and breeding plants that are resistant to this temperature-induced deformity. 'IFG Cher-ten' was specifically selected for its ability to produce normal fruit forms even in high-temperature environments, transforming the previously harmful thermal condition into a manageable parameter.
3Duration of action of stationary object
If existing varieties are used, then they can be grown, but they have poor stem attachment and storage characteristics
Solution Approach 1:
The patent applies self-service by developing a variety where the stem and fruit structure inherently provide their own support and protection during storage. 'IFG Cher-ten' features strong stem attachment and stems that remain green and functional during storage, eliminating the need for external support structures and reducing mechanical damage during handling and storage operations.
4Speed
If varieties with early ripening are selected, then they can be harvested earlier, but they often have reduced firmness and storage quality
Solution Approach 1:
The patent applies parameter changes by simultaneously optimizing multiple fruit quality parameters. 'IFG Cher-ten' was bred to achieve early ripening (one of the earliest varieties) while maintaining exceptional firmness and storage quality. The variety combines parameters of early maturation with enhanced structural integrity, breaking the traditional trade-off between ripening speed and fruit firmness.

AI summary
This invention is a new and distinct sweet cherry variety denominated ‘IFG Cher-ten’. The new sweet cherry tree is characterized by producing large size, dark red fruits having reniform shape. Fruits ripen early, are firm with medium acidity and have a good cherry flavor. Fruit stems are long, medium thick, have strong attachment and stay green during storage and shipping. ‘IFG Cher-ten’ is self-incompatible having S1S3 pollen alleles. The tree has a medium-low chilling requirement of about 400 to 500 hours. It produces very few doubled and spurred fruits in high summer temperature regions.
