Barley Cultivar Claymore Trait Combination via Parent Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Barley breeders face challenges in developing stable, high-yielding barley varieties with desirable traits such as grain quality, disease resistance, and lodging resistance, as existing methods lack effective solutions for combining these characteristics in a single variety.
Innovation Solution
The development of the new barley cultivar Claymore, which is a two-row, mid-season maturing variety with improved grain yield, lodging resistance, and intermediate tolerance to diseases like stem rust and barley yellow dwarf virus, achieved through crossing CDC Copeland and Xena, and subsequent breeding techniques like backcrossing and tissue culture to enhance desired traits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional barley breeding methods are used to develop new varieties, then some desirable traits can be obtained, but it is difficult to combine multiple traits (high yield, disease resistance, lodging resistance) into a single variety
Solution Approach 1:
The patent combines multiple desirable traits (high yield, disease resistance, lodging resistance) into a single barley variety by crossing two parent varieties with complementary traits. The F1 hybrid inherits and combines these traits, resolving the contradiction between trait combination and breeding complexity.
Solution Approach 2:
The developed barley variety serves multiple functions simultaneously: it provides high grain yield, resistance to multiple diseases (stem rust, barley yellow dwarf virus), and lodging resistance. This multi-functionality resolves the contradiction by making a single variety adaptable to various farming conditions and requirements.
2Productivity
If barley varieties are bred for high grain yield, then productivity increases, but disease resistance and lodging resistance may be compromised
Solution Approach 1:
The patent merges high yield capability from one parent variety with disease resistance and lodging resistance from another parent variety. The F1 hybrid simultaneously expresses all these traits, resolving the contradiction between productivity and reliability.
Solution Approach 2:
The breeding process changes the genetic parameters of the barley variety by introducing new alleles from the second parent. This genetic parameter change enables the F1 hybrid to express improved traits in grain yield, disease resistance, and lodging resistance simultaneously.
3Ease of operation
If F1 hybrid seeds are produced by crossing barley cultivar Claymore with a second distinct barley plant, then hybrid vigor and improved traits are achieved, but the breeding process becomes more complex
Solution Approach 1:
The patent performs preliminary selection of parent varieties with complementary traits before crossing. This preliminary action simplifies the subsequent hybrid seed production process by ensuring that the F1 hybrid will automatically inherit desirable traits, reducing the need for complex selection procedures in later generations.
