Proso Millet Breeding via Genomic Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inadequate freshwater supplies and increased variability in annual rainfall due to climate change pose significant risks to crop failures and food shortages, as traditional crop production methods struggle to meet the growing demand for grain.
Innovation Solution
Development of higher-yielding Proso millet varieties, such as DLG40, DLG148, DLG149, and DLG240, through modern breeding approaches like genotyping-by-sequencing, high throughput phenotyping, and genomic selection, which are more water-efficient and adaptable to varying conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional crop production methods are used, then current agricultural practices can be maintained, but crop yields are insufficient to meet growing demand and water efficiency is poor
Solution Approach 1:
The patent applies parameter changes by developing new Proso millet varieties with genetically improved traits through modern breeding approaches. The varieties DLG40, DLG148, DLG149, and DLG240 exhibit altered physiological parameters including improved water use efficiency and higher yield potential, directly addressing the contradiction between productivity and water consumption
Solution Approach 2:
The patent replaces traditional mechanical breeding methods with modern genomic technologies including genotyping-by-sequencing, high throughput phenotyping, and genomic selection. This substitution enables more precise and efficient development of water-efficient, high-yielding varieties, resolving the contradiction by accelerating the breeding process and improving selection accuracy
2Productivity
If traditional breeding methods are used, then breeding processes are simple, but development time is excessive (15 years)
Solution Approach 1:
The patent replaces traditional mechanical breeding methods with modern genomic technologies including genotyping-by-sequencing, high throughput phenotyping, and genomic selection. This substitution accelerates the breeding process from 15 years to a significantly shorter timeframe by enabling more precise and efficient selection of desirable traits
Solution Approach 2:
The patent uses genomic information and phenotypic data as informational copies to predict and select desirable traits before actual expression. By creating digital models of plant genomes and phenotypes, the breeding process can identify superior varieties more quickly without waiting for full growth cycles, thereby increasing breeding speed while managing complexity through information-based approaches

AI summary
Several Proso cultivars are disclosed having improved yields. The technology relates to the seeds, plants, and plant parts of Proso cultivars; and further provides methods for producing progeny of Proso cultivars. The technology also relates to Proso cultivars or breeding cultivars, and plant parts derived from Proso cultivars; and to methods for producing other Proso cultivars, lines, or plant parts derived from Proso cultivars, and to the Proso plants, varieties, and their parts derived from use of those methods. The technology further relates to hybrid Proso seeds, plants, and plant parts produced by crossing improved-yield Proso cultivars with another Proso cultivar.
