Outlaw Garden Bean Cultivar Pod Trait Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved garden bean varieties that offer desirable traits such as straight, dark green, glossy pods and specific sieve sizes, with potential for genetic modification to introduce traits like herbicide resistance, pest resistance, and enhanced nutritional quality.
Innovation Solution
The development of a novel garden bean cultivar named Outlaw, which features straight, dark green, glossy pods primarily producing 3-sieve and/or 4-sieve pods, along with methods for producing seed, plants, and transgenic plants with added traits through crossing, tissue culture, and genetic engineering techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional garden bean varieties are used, then cultivation is straightforward, but pod characteristics such as straightness, color, glossiness, and sieve size consistency are insufficient
Solution Approach 1:
The patent applies parameter changes by selecting and breeding for specific quantitative traits including pod straightness, pod color intensity, pod glossiness, and sieve size distribution. Through controlled breeding programs, these parameters were optimized to produce pods with 70-85% straight pods, dark green color, high glossiness, and consistent 3-sieve and 4-sieve sizes, resolving the contradiction between trait consistency and breeding complexity
Solution Approach 2:
The patent employs preliminary action through extensive pre-breeding work including parental line selection, controlled pollination, and multiple generations of selection before releasing the final variety. The breeding program conducted preliminary selection for pod characteristics over several generations, establishing a stable genetic base that ensures consistent pod traits in the Outlaw cultivar without requiring complex management during commercial production
2Adaptability or versatility
If conventional breeding methods are used, then variety development is achieved, but introduction of specific traits like herbicide resistance and pest resistance is limited
Solution Approach 1:
The patent applies composite materials principle by combining multiple genetic traits from different parental sources into a single cultivar. The Outlaw variety integrates pod characteristics (straightness, color, glossiness, sieve size) with agronomic traits (herbicide resistance, pest resistance, yield components) through composite breeding, creating a multi-trait variety that combines the beneficial properties of different parental lines into one unified genotype
Solution Approach 2:
The patent uses intermediary techniques including molecular markers and selective breeding intermediates to facilitate the introduction of specific traits. Molecular markers serve as intermediaries to track and select for desired traits during breeding, while controlled cross-breeding creates intermediate generations that allow systematic introduction and stabilization of new traits like herbicide resistance and pest resistance
3Reliability
If garden bean varieties with improved pod characteristics are developed, then market value increases, but genetic uniformity and stability require rigorous breeding programs
Solution Approach 1:
The patent applies periodic action through structured, multi-generational breeding cycles with regular selection and evaluation phases. The breeding program implemented periodic cycles of controlled pollination, seed production, field evaluation, and selection over multiple generations to progressively improve and stabilize pod characteristics. This periodic breeding approach ensured genetic stability while maintaining systematic progress toward the target phenotype
Solution Approach 2:
The patent employs feedback mechanisms through systematic evaluation and selection based on measured pod characteristics. Each breeding generation underwent feedback-driven selection where pods were evaluated for straightness, color, glossiness, and sieve size, and only plants meeting specified thresholds were advanced to the next generation. This feedback loop ensured genetic stability and consistent expression of desired traits in the final cultivar
