Some All-Canadian Roses
by Fred Blakeney, Victoria, B.C.
Mr. Percy Wright of Saskatoon, Sask., must be considered one of the foremost hybridizers of species and near species roses in North America. He has been working on these roses for many years, and knows the reactions of various hardy roses when crossed with species roses.
His objective has always been to produce worthwhile garden roses that are hardy enough to withstand the extremely low temperatures of the Prairies in winter. [...]
Here is a list of Mr. Wright's originations in chronological order of introduction:
1943 "Golden Altai", single, cream flushed yellow.

Website/Catalog  (1949)  
 
"Golden Altai* - Altaica by Harison's Yellow again, like the Altai rose in every respect except that the flowers are a cream approaching pale yellow."
