Winter Dawn Strawberry Breeding for Winter Yield and Disease Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry varieties in west central Florida face challenges in producing high fruit yields during the winter and are susceptible to Colletotrichum crown rot and other diseases, limiting their commercial viability and propagation options.
Innovation Solution
The development of the 'Winter Dawn' strawberry variety, which is resistant to Colletotrichum crown rot and produces high yields during the winter, with medium to large fruit and moderate resistance to Botrytis and anthracnose fruit rot, allowing for successful asexual propagation and improved market window alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing strawberry varieties are grown in west central Florida during winter, then fruit production occurs, but yields are low and disease susceptibility is high
Solution Approach 1:
The patent applies parameter changes by selecting and breeding strawberry plants with specific genetic traits that alter their physiological response to winter conditions and disease pressure. The 'Winter Dawn' variety exhibits changed parameters including cold tolerance, disease resistance genes, and fruit production timing that differ from conventional varieties, enabling high yields during Florida's winter season when traditional varieties fail.
2Productivity
If strawberry varieties are bred for high winter yield, then productivity improves, but adaptability to local conditions may be compromised
Solution Approach 1:
The patent employs self-service by allowing the strawberry plants to naturally select and express traits suited to Florida's winter climate through controlled breeding. The plants themselves demonstrate adaptability by producing fruit during the specific November-February window when market demand exists, without requiring external intervention to modify their physiological behavior. The variety serves its own adaptation needs through selective breeding for local conditions.
3Stability of the object's composition
If strawberry plants are propagated asexually, then genetic consistency is maintained, but disease susceptibility may increase
Solution Approach 1:
The patent applies preliminary action by conducting disease resistance screening and selection during the breeding process before mass propagation occurs. The 'Winter Dawn' variety was selectively bred for Colletotrichum crown rot resistance, and only plants demonstrating this resistance were propagated asexually. This preliminary selection ensures that the genetic uniformity achieved through asexual propagation carries the desired disease resistance trait, preventing the amplification of susceptibility.

AI summary
A new and distinct variety of strawberry (Fragaria×ananassa), which originated from seed produced by a hand-pollinated cross between FL 93-103 and FL 95-316. The new strawberry, named ‘Winter Dawn’, is distinguished by high November through February production of fruit that are medium to large in size and moderately resistant to Botrytis and anthracnose fruit rot diseases when grown in Dover, Fla. or other areas that have a subtropical climate similar to that of Dover.
