  14. 14. Most Important Results of the Trap Nurseries In summer season of 2006 Yr1in shiness166 was susceptible with a score of 50S for the first time while in winter showed score of 0. Till the year of 2010 Yr1 was infected with strip rust and continue to be susceptible up to winter 2014 with a scoring varied between 5S to 50S in the Central Highlands region. Yr32 in CarstensV gene showed yellow rust infection in the winter season 2014 in the Central Highlands. This is for the first time to be observed. In 2007 yellow rust infection was observed on the following genes; Yr27 in summer season, yr31 in summer season, YrAPR in summer season, YrND in winter season, Yrsp splading prolific in winter season and Yr31 in winter season in the Central Highlands. In 2007, in Southern Uplands, Yr1 In Avocet, Yr10 in Avocet and Yrsp in Avocet stil with Yr10 and Yrsp showed yellow rust infection. Also, in Southern Uplands, Yr17 was infected with Yellow rust in 2010.
