Plared 0822 Strawberry Variety Early Ripening and Fruit Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current strawberry varieties lack a combination of desirable traits such as inflorescence above foliage, large conical medium to red-colored fruit, firm flesh, and very early flowering and ripening times, which are not adequately addressed by existing cultivars.
Innovation Solution
The development of the strawberry variety 'Plared 0822' through crossing '00-174R' and '09-030', involving thermotherapy and asexual propagation, results in a fully remontant strawberry with unique characteristics like inflorescence above foliage, medium to large conical fruit, and very early flowering and ripening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional strawberry varieties are used, then they have established growth patterns, but they lack the combination of desirable traits including inflorescence above foliage, large conical fruit, firm flesh, and very early flowering and ripening
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters of strawberry plants through controlled crossing between specific parent varieties. This results in a new variety with altered growth parameters including inflorescence position (above foliage), fruit characteristics (large, conical, firm), and phenological parameters (very early flowering and ripening). The parameter changes are achieved through selective breeding that combines desirable traits from different parent lines.
2Reliability
If thermotherapy and asexual propagation are used to establish head clones, then the variety traits are fixed and retained true to type, but the propagation process requires multiple steps including heat treatment, meristem cutting, and vitro culture
Solution Approach 1:
The patent applies preliminary action by performing thermotherapy (heat treatment at 36-37°C for 3-4 weeks) on mother plants before asexual propagation. This preliminary step eliminates viruses and ensures health of the propagating material. The process then proceeds to meristem cutting and in vitro culture, which are subsequent steps that maintain trait fidelity. The preliminary action of thermotherapy ensures reliable propagation while managing the complexity through a standardized multi-step protocol.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The new variety 'Plared 0822' exhibits improved fruit production, yield, and specific traits like upright growth habit, overlapping petals, and upwards sepal attitude, distinguishing it from parent and closest varieties, with enhanced commercial quality and storage qualities.
Implementation Method 1
mother plants that had developed several stolons were subjected to a heat treatment, or Thermotherapy, at 36° C. −37° C. for 3 to 4 weeks
