Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for stable, high-yielding sweet corn hybrids with improved agronomic and horticultural traits, such as increased yield, better ear and kernel quality, and enhanced nutritional content, which existing sweet corn breeding methods struggle to consistently achieve.
Innovation Solution
The development of the hybrid sweet corn variety 'SUMMER CELEBRATION' and methods for producing and propagating it, including vegetative propagation, tissue culture, and genetic modification to introduce desired traits like disease resistance, drought tolerance, and improved nutritional quality, using techniques like CRISPR/Cas system for genome editing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sweet corn breeding methods are used, then basic yield and quality traits can be maintained, but stable high-yielding hybrids with improved agronomic and horticultural traits cannot be consistently achieved
Solution Approach 1:
The patent applies parameter changes by systematically varying multiple breeding parameters including crossing different inbred lines (P3, P4, P6, P7), evaluating across multiple locations and years (2017-2019), and selecting for specific trait combinations. This multi-parameter approach transformed conventional breeding into a systematic process that consistently produces high-yielding hybrids with improved agronomic and horticultural traits.
Solution Approach 2:
The patent achieves universality by developing hybrid sweet corn varieties that simultaneously excel in multiple functions: high yield production, disease resistance (Northern Corn Leaf Blight, Gray Leaf Spot), abiotic stress tolerance (drought, heat), and superior eating quality. The SUMMER CELEBRATION hybrid exemplifies this multi-functionality by combining 18-20 rows, 32-36 kernels per row, and enhanced nutritional content while maintaining stability across diverse growing conditions.
2Adaptability or versatility
If multiple traits are improved simultaneously, then comprehensive hybrid performance is enhanced, but breeding complexity and selection difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the breeding program into distinct phases: developing parental inbred lines with specific trait combinations, evaluating F1 hybrids across multiple locations and years, and selecting for specific trait combinations (18-20 rows, 32-36 kernels per row). This segmented approach made the complex multi-trait breeding program manageable and reproducible.
Solution Approach 2:
The patent applies local quality by assigning specific trait emphases to different parental lines and evaluation contexts. Parental lines P3, P4, P6, and P7 were developed with complementary trait profiles, and evaluation priorities were adjusted based on location and year conditions, allowing optimal expression of different trait combinations in different environments.
3Reliability
If disease resistance and stress tolerance are incorporated, then crop reliability is improved, but yield potential may be compromised
Solution Approach 1:
The patent applies merging by combining disease resistance genes (Northern Corn Leaf Blight, Gray Leaf Spot resistance) and abiotic stress tolerance traits (drought resistance, heat tolerance) into parental inbred lines that also possess high yield potential. The resulting SUMMER CELEBRATION hybrid demonstrates that these protective traits and high yield (18-20 rows, 32-36 kernels per row) can coexist and reinforce each other.
