Multivariate analysis of stripe rust assessment and reactions of barley in multi-location nurseries.

The article presents a study on multivariate analysis of stripe rust assessment and reactions of barley in multi-location nurseries. The researchers evaluated 1358 hulled two-row, hulled six-row, and hulless barley in Toluca, Mexico in 2007, in Quito, Ecuador in 2007 and 2008, and Pullman and Mt. Vernon in the U.S. in 2007-2009. The results show that the two-row types of barley were more resistant than the six-row and hulless types.
