Research Project: Genotyping of Sorghum for Grain Quality Traits

Location: Grain Quality and Structure Research

Project Number: 3020-43440-001-06-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 1, 2016
End Date: Jul 31, 2018

The overall objective of this cooperative project is to establish relationships between genes and genetic markers and grain composition and end-use quality traits.

Sorghum lines known to have yellow pericarp or endosperm will be grown to the seedling stage and leaf tissue harvested for DNA extraction and sequencing/genotyping. The same samples will be grown to maturity in Manhattan and grain harvested for basic grain proximate composition, carotenoid content as well as carotenoid content and composition. In addition, grain samples from nested association mapping (NAM) populations will be harvested and analyzed for grain composition. Grain quality data will be analyzed and compared to agronomic and genotypic data collected on these same sample sets to identify agronomic and genetic factors that impact grain composition.
