| dc.description.abstract | A total of 519 lines were tested in Kenya against stem rust (Ug99 lineage pathotypes – TTKSK, TTKST, TTKTT, TTTTF and TTKTT+Sr8115B) and stripe rust (race PstS16). The tested lines were derived from two resistant genotypes: Kenya Kudu (an east African line) and Kingbird (a CIMMYT line released in Ethiopia) both of which have showed good levels of resistance (characterized and/or uncharacterized) to all three rusts in field trials at PBI Cobbitty. These lines were crossed with Avocet to develop DH populations. High quality data was generated on these lines with two readings each for stem rust and stripe rust at 10-day interval (data file attached). | en_AU |

| dc.description.method | Wheat stem rust (WSR) and stripe rust (WYR) screening was conducted at Nojoro, Kenya, the field plots comprised 1 m paired rows sown on top of 0.8 m wide raised beds. For stem rust screening at Kenya, a mixture of urediniospores of races in the Ug99 lineage (TTKSK, TTKST, TTKTT, TTTTF and TTKTT+Sr8115B) were inoculated onto susceptible spreaders (Duma and Chozi) to facilitate uniform disease development. Although the primary purpose of screening in Kenya is stem rust, data was also collected for stripe rust that appeared naturally in field (primarily race Pst16). Disease severity was recorded according to a modified Cobb Scale by recording disease score [0-100%] and host response [R = Resistant; MR = moderately resistant; MR-MS = moderately resistant to moderately susceptible; MS = moderately susceptible; S = susceptible] when the severity on the respective susceptible check varieties reached 90-100S. | en_AU |
