Rustler Pinto Bean Breeding for Lodging Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for healthier food products that incorporate the nutritional benefits of legumes, such as beans, which are underutilized in the US diet, and a consistent crop supply to address obesity and poor eating habits.
Innovation Solution
A new pinto bean variety, RUSTLER, is developed for breeding and as a foodstuff, characterized by its physiological and morphological traits, including an erect growth habit, medium to long guides, scattered pods, and good lodging resistance, suitable for machine harvest, with methods for breeding and tissue culture to produce uniform and stable seeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If legumes are promoted as healthy food to address obesity and poor eating habits, then nutritional benefits are improved, but consistent crop supply is insufficient
Solution Approach 1:
The patent segments the breeding process into distinct generations (F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12) with specific selection criteria for each stage, enabling systematic development of reliable crop varieties that can be consistently supplied to address the underutilization of legumes in the US diet
Solution Approach 2:
The patent performs preliminary breeding and selection actions in advance, developing the RUSTLER bean line through multiple generations of controlled crosses and selections before commercial deployment, ensuring consistent crop supply and nutritional benefits are achieved before market introduction
2Ease of operation
If bean varieties are developed for machine harvest with erect growth habit and scattered pods, then ease of harvest is improved, but breeding complexity increases
Solution Approach 1:
The breeding program is segmented into specific generational stages with defined selection criteria, where erect growth habit and scattered pod distribution are targeted at particular generations (e.g., F5-F8 for plant architecture, F7-F12 for pod characteristics), making the complex breeding process manageable and systematic
Solution Approach 2:
The patent systematically changes key parameters during breeding: plant architecture (erect growth habit), pod distribution (scattered), and maturity timing are adjusted across generations to achieve machine harvest adaptability while maintaining genetic stability through controlled parameter transitions
