PH3261MR Sorghum Inbred Line for Disease, Drought, and Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sorghum varieties lack a combination of desirable traits such as disease resistance, drought tolerance, and high yield, making them less effective in challenging agricultural conditions.
Innovation Solution
Development of the sorghum line PH3261MR, which incorporates multiple desirable traits through backcross conversion and genetic transformation, enhancing resistance to diseases, insects, and improving yield and drought tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional plant breeding through inbred varieties is used, then uniformity of plant characteristics is improved, but the combination of multiple desirable traits (disease resistance, drought tolerance, high yield) is limited
Solution Approach 1:
The patent combines multiple desirable traits (disease resistance, drought tolerance, high yield) into a single sorghum inbred line PH3261MR through systematic breeding programs that cross and select for multiple traits simultaneously, resolving the contradiction between trait combination and uniformity
Solution Approach 2:
The inbred line PH3261MR is developed as a universal parent line that can be crossed with various other lines to produce hybrids with different combinations of traits, making it adaptable to multiple agricultural conditions while maintaining uniformity of its own characteristics
2Ease of manufacture
If existing sorghum varieties are used, then ease of cultivation is maintained, but resistance to diseases and insects and drought tolerance are insufficient
Solution Approach 1:
The inbred line PH3261MR is pre-developed with built-in resistance to diseases, insects, and drought through multiple generations of selection and backcrossing, so that farmers can plant it directly without additional interventions, maintaining ease of cultivation while improving reliability
3Productivity
If existing sorghum varieties are used, then current yield levels are achieved, but yield potential and performance under adverse conditions are limited
Solution Approach 1:
The patent changes the genetic parameters of the sorghum line by introducing and selecting for multiple disease resistance genes and drought tolerance genes through backcrossing with resistant parent lines, thereby improving both yield potential and performance under adverse conditions
