Maize Hybrid 10139630 Segmentation for Yield and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maize breeding techniques face challenges in combining desirable traits such as disease resistance, drought tolerance, and high yield while maintaining uniformity and stability in maize varieties, particularly in achieving optimal agronomic performance and resistance to environmental stresses.
Innovation Solution
Development of the maize variety 10139630 through crossing proprietary Pioneer Hi-Bred International inbred varieties, incorporating locus conversion and transformation to introduce specific traits, and using methods like backcrossing and transformation to enhance genetic integrity and introduce desirable characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plant breeding is used to combine desirable traits, then disease resistance and drought tolerance can be improved, but uniformity and phenotypic stability may deteriorate
Solution Approach 1:
The patent segments the breeding process into distinct stages: developing inbred lines with specific traits, then crossing them to create hybrids. This segmentation allows for controlled combination of desirable traits while maintaining uniformity through the systematic nature of hybridization.
Solution Approach 2:
The patent applies preliminary action by first developing and stabilizing inbred parent lines with specific desirable traits (disease resistance, drought tolerance) before crossing them. This preliminary stabilization ensures that the resulting hybrids will exhibit uniform phenotypic expression of these traits.
2Productivity
If multiple desirable traits are combined in a single hybrid, then agronomic performance is improved, but the complexity of breeding increases
Solution Approach 1:
The breeding program is segmented into separate functional components: one parent line contributes disease resistance, another contributes drought tolerance, and their cross produces the hybrid with combined traits. This segmentation simplifies the overall breeding complexity by dividing trait combination into manageable parental contributions.
Solution Approach 2:
The patent merges multiple desirable traits from different inbred parent lines into a single hybrid variety. By combining traits at the parental level rather than attempting to accumulate them sequentially in a single line, the breeding process complexity is reduced while achieving high agronomic performance.
3Productivity
If inbred varieties are crossed to produce hybrids, then yield and uniformity are improved, but the time to crop maturity may increase
Solution Approach 1:
The patent optimizes the parental inbred lines for complementary parameters: one parent may be selected for slightly earlier maturity while contributing disease resistance, another for drought tolerance. The hybrid combines these parameters to achieve acceptable maturity timing while maintaining high yield and uniformity, thus reducing the time loss associated with hybrid development.
