January 2017: NSGC Durum Wheat Stem Rust genotype and phenotype data are available

Phenotype and mapping data from a genome-wide association study of stem rust resistance in durum wheat are available in the GrainGenes database prior to publication. A panel of 429 lines from the National Small Grains Collection were used in the study to evaluate the genetic diversity of durum wheat resistance to a variety of stem rust races. Several quantitative trait loci for seedling stage and adult plant resistance to a collection of stem rust races were identified. A number of the QTL are potentially novel genes.

November 2016: A new twitter feed section and a Facebook page

GrainGenes front page has now a new twitter feed section coming from @graingenes (https://twitter.com/graingenes). We also created a new Facebook page (https://www.facebook.com/graingenes/). Both of which, we hope, will allow us to connect directly with our users and share items that will be of interest for small grains researchers.

We appreciate if you please like & follow us.

Thank you!
The GrainGenes team
