DescriptionDifferential resistance to stripe rust (Puccinia striiformis) in a planting of 111 wild collections of Basin wild rye (Leymus cinereus) was noted 2011-2013. In 2011, rust severity was rated on a scale of 1-9. Much lighter infection in 2012 and 2013 was rated as the number of symptomatic leaves per plant divided by plant circumference (to adjust for plant size). Effect of collection was significant in 2011 (P = 0.0042), 2012 (P = 0.0032), and 2013 (P = 0.0095), with a relatively weak (0.23) but significant (P = 0.0149) correlation between 2011 and 2012 and a stronger (0.38) and highly significant (P < 0.0001) correlation between 2012 and 2013. Correlation between results of 2011 and 2013 was near zero and insignificant unless the ratings from 2011 were adjusted for plant size. Representative resistant and susceptible collections will be conserved as accessions in the National Plant Germplasm System.
