Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tomato breeding techniques face challenges in developing uniform, high-yielding, disease-resistant, and environmentally adapted varieties that meet diverse consumer demands for fruit quality and processing needs, with existing methods often resulting in unpredictable performance due to genetic non-uniformity in hybrid plants.
Innovation Solution
The development of the tomato variety NUN 09085 TOF, which is characterized by specific morphological and physiological traits, including flower number, inflorescence type, dedicel length, fruit locules, and size, and is propagated through seed production and vegetative methods to maintain genetic stability and uniformity, while also offering resistance to certain diseases and pests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cross-pollination is used to create hybrid plants, then genetic diversity and adaptability are improved, but genetic uniformity and performance predictability deteriorate
Solution Approach 1:
The breeding program segments the genetic material into distinct homozygous inbred lines that are maintained separately. These inbred lines serve as stable building blocks that can be consistently crossed to produce uniform hybrid offspring, resolving the contradiction between genetic diversity and performance predictability.
Solution Approach 2:
The patent changes the genetic parameter state by creating homozygous inbred lines through multiple generations of self-pollination. This parameter change (from heterozygous to homozygous state) ensures that the parental lines are genetically uniform, which in turn produces predictable and uniform hybrid F1 generations with consistent performance.
2Reliability
If self-pollination is used to create homozygous inbred plants, then genetic uniformity is improved, but genetic diversity and adaptability deteriorate
Solution Approach 1:
The breeding program segments the overall breeding goal into two phases: first creating genetically uniform homozygous inbred lines through self-pollination, then crossing these segmented lines to generate genetic diversity in the hybrid F1 generation. This segmentation resolves the contradiction between uniformity and diversity.
Solution Approach 2:
The patent applies preliminary action by first developing homozygous inbred lines through extended self-pollination before the crossing stage. This preliminary creation of uniform parental lines ensures that subsequent hybrid crosses produce predictable, uniform offspring with desired traits, resolving the contradiction between uniformity and adaptability.
3Adaptability or versatility
If multiple breeding methods are used to combine desirable traits, then trait diversity is improved, but breeding complexity and time required deteriorate
Solution Approach 1:
The breeding program segments the complex task of combining multiple traits into manageable phases: developing individual homozygous inbred lines with specific traits, then systematically crossing these lines. This segmentation reduces breeding program complexity while maintaining trait diversity.
Solution Approach 2:
The patent uses parameter changes by transitioning from heterogeneous breeding populations to homozygous inbred lines, then to uniform F1 hybrids. This parameter transformation simplifies the breeding process by creating distinct, stable genetic states that are easier to manage and predict, reducing overall program complexity.
