necessary, in this one stage upon the single species of host. 

 While no variety of wheat is entirely proof against it, large 

 difference is shown in this respect, some presenting high 

 resistance, even under most adverse conditions. Early 

 maturity is an important factor in evading rust. 



The following standard varieties are recommended by 

 Carleton as possessing considerable resistance to the orange- 

 leaf -rust in every part of the country — "Winter wheats: 

 Turkey, Mennonite, Pringles No. 5, Tieti, Odessa, Pringles 

 Defiance. Spring wheats: Haynes Blue Stem, Saskatche- 

 wan Fife. 



"The following varieties seem to be resistant, but have not 

 yet been well established as such: Theiss, Oregon Club, 

 Sonora, Diehl Mediterranean, Fulcastgr, Arnolds Hybrid, 

 California Spring. 



"Some of the hardy prolific sorts not yet well known in this 

 country, but likely to be more or less rust-resistant after 

 thorough acclimation and selection, are — Winter wheats: 

 Prolifero, Banatka, Red Winter, Nashi, Tangarotto, Bearded 

 Winter, Winter Ghirka, Budapest, Crimean, Yx, Bellevue, 

 Talavera. Spring wheats: Alsace, Spring Ghirka. 



"Two varieties which are quite susceptible to rust, but 

 which usually ripen early enough to escape the worst effects 

 of it, are: Early May and Zimmerman. 



"Some others not quite so well known, but probably 

 worthy of trial as rust-escaping sorts, are — Early Baart, 

 Allora Spring, Kathia, Roseworthy, Japanese No. 2, Yemide, 

 Canning Downs. 



"These last varieties are not likely to withstand very 

 severe winters, and are therefore best adapted to southern 

 districts, where they may perhaps in time become accli- 

 mated. Yemide and Kathia are jn-obably the most hardy 

 of the six. Canning Downs winter-killed in one trial, even 

 in Mississippi." 



Yellow-stripe-rust {Puccinia glumarum (Schum.) E. & 

 H.). — This rust, which is serious in Europe on wheat and 

 barley and less so on rye and several wild grasses, was found in
