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.
