Solution Overview
Problem
Current wheat breeding methods face challenges in efficiently combining desirable traits such as higher seed yield, disease resistance, and improved agronomic characteristics in a single wheat variety.
Innovation Solution
The development of the new wheat variety PMWH149312414, which involves crossing and backcrossing with other wheat plants to introduce specific traits, followed by selection and breeding to achieve desired combinations of characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wheat breeding methods are used to combine desirable traits, then multiple traits can be introduced through crossing and backcrossing, but the process requires numerous steps involving significant intervention and takes considerable time
Solution Approach 1:
The patent applies preliminary action by pre-selecting parental germplasm with specific desirable traits before initiating the breeding program. The parental lines are carefully chosen to possess target characteristics such as disease resistance, yield potential, and agronomic quality, which are then combined through controlled crossing and backcrossing operations to achieve the desired trait combination more efficiently
2Reliability
If extensive crossing and backcrossing is performed to achieve desired trait combinations, then improved seed yield, disease resistance, and agronomic characteristics can be obtained, but the breeding program complexity increases significantly
Solution Approach 1:
The breeding program is segmented into distinct phases: initial crossing to combine traits from different parental lines, followed by systematic backcrossing to recover the recurrent parent genome while retaining desired traits, and finally selection and stabilization phases. This segmentation allows complex trait combinations to be achieved through manageable, sequential steps rather than attempting all operations simultaneously
Solution Approach 2:
The patent implements feedback mechanisms through continuous evaluation and selection at each breeding stage. Plants are assessed for presence of desired traits, and only those meeting selection criteria advance to the next generation. This feedback loop ensures trait stability and uniformity while guiding the breeding program toward the target genotype, reducing unnecessary complexity by eliminating non-conforming lines early
