Garden Bean Breeding via Preliminary Parent Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of new garden bean cultivars is a time-consuming process due to the unpredictability of genetic combinations and the difficulty in identifying superior plants, which leads to high research costs and resource inefficiencies.
Innovation Solution
The introduction of six novel garden bean cultivars (HMX4101, HMX4127, HMX4129, HMX5106, HMX5107, and HMX5108) with specific phenotypic and morphological characteristics, along with methods for producing transformed plants with desired traits such as disease resistance and improved yield, using backcrossing and tissue culture techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional breeding methods are used to develop new garden bean cultivars, then genetic diversity and trait combinations can be achieved, but the process becomes time-consuming and resource-intensive
Solution Approach 1:
The patent applies preliminary action by pre-selecting and characterizing parental lines with specific desirable traits before crossing. The parental germplasm is evaluated and selected based on predetermined criteria for disease resistance, yield, and other agronomic qualities, allowing the breeding program to start with optimized parents rather than exploring random combinations.
Solution Approach 2:
The patent implements feedback through systematic evaluation and selection processes at multiple generations. Performance data from field trials, disease resistance assessments, and yield measurements are collected and used to guide subsequent selection decisions, allowing breeders to iteratively improve cultivars based on measured outcomes rather than random selection.
2Reliability
If extensive field testing and evaluation are conducted to identify superior plants, then reliable selection can be made, but research costs and resource requirements increase
Solution Approach 1:
The patent reduces resource requirements by conducting preliminary evaluations of parental lines for key traits such as disease resistance and agronomic quality before initiating crosses. This pre-characterization allows selection of parents that are most likely to produce superior offspring, reducing the number of lines that need extensive field testing.
Solution Approach 2:
The patent uses replicated evaluations of families of related plants to obtain mean values for selection, rather than testing every individual plant extensively. By evaluating representative samples and using statistical means, the program achieves reliable selection with reduced resource investment compared to exhaustive individual plant testing.
3Manufacturing precision
If multiple generations are advanced through repeated crossing and selection, then superior cultivars can be developed, but the breeding program becomes complex and difficult to manage
Solution Approach 1:
The patent divides the breeding program into distinct phases and generations (F1, F2, F3, etc.), with specific objectives for each stage. Early generations focus on combining parental traits, intermediate generations on selecting for desired characteristics, and later generations on stability testing. This segmentation makes the complex multi-generational process more manageable and systematic.
Solution Approach 2:
The patent uses intermediate breeding populations and family evaluations as mediators between parental lines and final cultivars. Rather than directly selecting final cultivars from random crosses, the program progresses through intermediate generations that serve as transitional stages, allowing systematic improvement while maintaining program organization and trackability.
