White Strawberry Cultivar BBB PO 01 Breeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry cultivars with white fruit lack desirable traits such as firmness, juiciness, aroma, and flavor, and often exhibit mealy texture and inconsistent fruit shape.
Innovation Solution
The development of the new strawberry cultivar 'BBB PO 01', which results from open pollination between Fragaria cultivars like 'Annablanca' and 'Louis Gathier', exhibits unique characteristics including white berries with red achenes, improved firmness, juiciness, aromatic fragrance, and better flavor, achieved through asexual reproduction by stolon cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If white-fruited strawberry cultivars are developed, then fruit color is improved, but firmness and juiciness deteriorate
Solution Approach 1:
The patent applies parameter changes by selecting and breeding plants with specific genetic combinations that alter the biochemical parameters of fruit development. Through controlled pollination and selection over multiple generations, the cultivar 'BBB PO 01' was developed with modified parameters including firmness (1.5-2.0 kgf), juiciness (85-95% water content), and fruit color (white with red achenes), resolving the contradiction between achieving white fruit color while maintaining desirable firmness and juiciness characteristics
2Shape
If white-fruited strawberry cultivars are developed, then fruit color is improved, but aroma and flavor deteriorate
Solution Approach 1:
The breeding program systematically changed aromatic and flavor parameters through selective reproduction. The resulting cultivar exhibits perfume-like fragrance and superior flavor with balanced sweetness and acidity, achieving both white fruit color and reliable sensory quality through multi-generational selection and controlled pollination
3Productivity
If existing white-fruited cultivars are propagated, then propagation is achieved, but fruit shape consistency deteriorates
Solution Approach 1:
The patent applies preliminary action through extensive pre-breeding work and selection before final cultivar establishment. Multiple generations of controlled pollination, seedling evaluation, and phenotypic selection were conducted to pre-establish genetic stability for consistent fruit shape (conical to heart-shaped, 2.5-3.5 cm length, 2.0-3.0 cm width) before asexual propagation, ensuring both propagability and shape uniformity
