Summary of the significant markers identified through Kruskal–Wallis test in MapQTL software for leaf, stem and stripe rust from a doubled haploid population of Sachem/Strongfield screened for disease resistance for leaf rust (Lr) severity (%) in field nurseries (El Batan, Obregon, Toluca 2009 and 2011, Mexico) and greenhouse (seedling response infection type) at CIMMYT, Mexico (races BBG/BN and BBG/BP)

Stem rust (Sr) reaction (% severity and infection type) was recorded from Ug99 nursery near Njoro, Kenya, while stripe rust (Yr) ratings were collected from Toluca in 2009 and 2011 and Njoro, Kenya nursery in 2011
