Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved garden bean varieties that are stable, high-yielding, and agronomically sound, with resistance to diseases such as Anthracnose and bean rust, and adapted for heat tolerance and machine harvestability.
Innovation Solution
The development of a new garden bean variety 'PV-857' with specific physiological and morphological characteristics, including resistance to Anthracnose and bean rust, heat tolerance, and an erect plant habit, achieved through breeding techniques such as recurrent selection and backcrossing, which also allows for the production of commodity plant products like protein concentrate and vegetable bean flour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If garden bean varieties are bred for high yield and stability, then productivity and reliability improve, but resistance to diseases and environmental adaptability may be compromised
Solution Approach 1:
The patent applies parameter changes by systematically varying breeding parameters through recurrent selection and backcrossing to achieve optimal combination of yield and disease resistance. The breeding process modifies genetic parameters over multiple generations to simultaneously improve productivity and reliability traits.
Solution Approach 2:
The patent creates a composite genetic structure by combining desirable traits from different parental lines through backcrossing. The resulting variety 'PV-857' integrates high-yield genes with disease resistance genes, creating a composite genetic material that exhibits both high productivity and reliability.
2Adaptability or versatility
If garden bean varieties are bred for heat tolerance and disease resistance, then adaptability and reliability improve, but yield and machine harvestability may be compromised
Solution Approach 1:
The patent uses parameter changes to adjust the thermal tolerance parameters of the garden bean variety through controlled breeding. By selecting for heat tolerance while monitoring yield parameters, the breeding process optimizes the balance between adaptability and productivity.
Solution Approach 2:
The patent applies preliminary action by pre-selecting parental lines with known heat tolerance characteristics before initiating the breeding program. This preliminary selection ensures that the breeding process starts with genetic material that already possesses the desired adaptability traits, making it easier to maintain both heat tolerance and high yield.
3Reliability
If garden bean varieties are bred for disease resistance, then reliability improves, but agronomic performance and yield stability may be compromised
Solution Approach 1:
The patent creates composite genetic material that combines multiple resistance genes with yield stability genes. Through backcrossing with selected parental lines, the variety integrates diverse genetic traits that work together to provide both disease resistance and consistent yield performance across different growing conditions.
Solution Approach 2:
The patent implements feedback mechanisms in the breeding program by continuously evaluating disease resistance and yield stability parameters across multiple generations and environmental conditions. This feedback information guides subsequent selection decisions to optimize both reliability and stability traits.
4Ease of operation
If garden bean varieties are bred for machine harvestability, then ease of operation improves, but plant architecture and yield may be compromised
Solution Approach 1:
The patent applies parameter changes to modify plant architecture parameters such as plant height, pod position, and uniformity of maturity to improve machine harvestability. These architectural parameter changes are achieved through selective breeding while maintaining or improving yield parameters.
