DrisStrawFortyOne Strawberry Yield and Trait Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a new strawberry variety that retains distinctive characteristics through asexual propagation and offers improved yield, plant habit, and fruit characteristics compared to existing varieties.
Innovation Solution
The development of the strawberry variety 'DrisStrawFortyOne' (Fragaria×ananassa), which is the result of a cross between proprietary parents '131N177' and '142N322', exhibiting dense plant growth, dark red fruit, and mid-season harvest maturity, and has been successfully propagated via tissue culture and vegetative cuttings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a new strawberry variety is developed through cross-breeding, then fruit characteristics and yield are improved, but maintaining distinctive characteristics through propagation becomes challenging
Solution Approach 1:
The patent applies preliminary action by selecting and propagating the strawberry variety through controlled asexual propagation methods (tissue culture and vegetative cuttings) from the beginning of the breeding program. This ensures that the distinctive characteristics are preserved from the moment of selection through successive propagations, rather than attempting to restore characteristics after they are lost.
Solution Approach 2:
The patent employs copying through asexual propagation via tissue culture and vegetative cuttings to create genetically identical copies of the selected plant. This ensures that the distinctive characteristics of the new variety are exactly replicated in subsequent generations without the genetic variation that would occur in sexual reproduction.
2Productivity
If plant density is increased to improve yield, then productivity increases, but plant health and vigor may deteriorate
Solution Approach 1:
The patent applies local quality by creating a dense plant habit where the foliage is densely packed, but the individual plants maintain adequate spacing and resources. The new variety exhibits a compact, dense growth pattern that maximizes yield per unit area while preventing the deterioration of individual plant health through optimized resource distribution within the plant structure.
3Volume of moving object
If fruit size is increased, then marketability improves, but plant vigor and disease resistance may decrease
Solution Approach 1:
The patent applies parameter changes by modifying the genetic parameters of the strawberry variety through controlled cross-breeding to achieve larger fruit size while simultaneously improving disease resistance. The new variety 'DrisStrawFortyOne' exhibits both larger fruits and moderate resistance to diseases and pests, representing a favorable change in multiple genetic parameters simultaneously.
