Wheat Cultivar Breeding for Multi-Trait Yield and Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheat cultivars lack improved combinations of desirable traits such as higher seed yield, disease resistance, insect resistance, drought tolerance, heat tolerance, better agronomic quality, and herbicide resistance, which are essential for enhancing wheat productivity and versatility in various applications.
Innovation Solution
Development of the wheat cultivar 01102455, which includes genetic modifications and traditional breeding techniques to introduce traits like herbicide resistance, insect resistance, disease resistance, and improved nutritional quality, along with the use of transgenic genes and tissue culture methods to regenerate plants with desired characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional breeding techniques are used to develop wheat cultivars, then genetic diversity is maintained, but the speed of introducing multiple desirable traits is slow
Solution Approach 1:
The patent applies preliminary action by pre-introducing multiple desirable traits into the parental germplasm before crossing. The cultivar 01102455 was developed by selecting parents that already possessed target traits (disease resistance, yield potential, agronomic quality) and then performing controlled crosses to combine these traits in the progeny, thereby accelerating the breeding process compared to traditional sequential selection methods.
2Adaptability or versatility
If multiple desirable traits are combined in a single wheat cultivar, then overall performance and versatility are improved, but the complexity of breeding program increases
Solution Approach 1:
The patent applies merging by combining multiple desirable traits from different parental lines into a single cultivar 01102455. The breeding program integrated traits including disease resistance, insect resistance, drought tolerance, heat tolerance, herbicide resistance, and improved agronomic quality from various parent cultivars through systematic crossing and selection, creating a multi-trait cultivar that addresses multiple production challenges simultaneously.
Solution Approach 2:
The patent applies universality by developing cultivar 01102455 with broad-spectrum resistance to multiple diseases (rust, powdery mildew, leaf spot), insects, and environmental stresses (drought, heat), along with improved yield and agronomic quality. This multi-functional cultivar can be used across diverse growing conditions and management systems, reducing the need for multiple specialized cultivars.
3Reliability
If disease resistance and insect resistance are introduced into wheat cultivars, then crop protection is improved, but yield potential may be compromised
Solution Approach 1:
The patent applies local quality by introducing disease and insect resistance traits into specific regions of the genome through targeted crossing and selection, while maintaining the high-yield genetic background in other regions. The cultivar 01102455 combines resistance genes from disease-resistant parent lines with high-yield genes from productive parent lines, allowing simultaneous expression of both resistance and yield potential without mutual interference.
