Phenotype Core

Phenotypic Characterization of Wild Wheat Core Sets

Project Summary:

Core collections of Aegilops tauschii (40 accessions) and tetraploid wheat (92 accessions) were phenotyped for important traits in greenhouse, field and rainout shelter experiments.  These core sets had greenhouse data collected during the years of 2015-2018 for resistance to leaf rust, stripe rust, tan spot, Septoria nodorum Hessian fly, wheat curl mite, Russian wheat aphid and greenbug.  During the same period core sets were planted in Rocky Ford field plots in Manhattan with data collected for resistance to powdery mildew, adult plant resistance to leaf rust, barley yellow dwarf, stripe rust, winter hardiness, flowering date, and stay-green (STG) traits.  Two replications of these core collections were also planted in rainout shelters and one replication in normal field setting at the Agronomy North Farm for two growing seasons for drought tolerance screening.  As established with the Ae. tauschii and tetraploid core sets a pilot study of the wild wheats representing the A-genome of wheat is currently undergoing screening for the same disease, insect and agronomic traits in both the greenhouse and field.
