Abstract
Awns and callus hairs are significant dispersal traits of Miscanthus - understanding them will be essential in domesticating this crop. Due to their small size, these structures can be challenging to phenotype. To aid this, a method has been developed for automated length measurement via computational image analysis in Python. Lengths for both structures have been collected and processed for all plants in both the Mississippi State University and Alabama A&M University research fields. The measurements from both sites were compiled and mapped against the Miscanthus genome to create multiple Quantitative Trait Loci (QTL) maps of inflorescence trait-affecting genes. Chromosomes 3 and 6 consistently showed an effect on awns, while chromosome 19 showed an effect on callus hair length at the Alabama A&M research site and in the combined data set of both locations but did not show an effect in the Mississippi State University data set.
