characteristics of each. Tlie varieties dealt with include 24 strains of durum 

 wheat, 17 common benrded sorts, and 41 beardless types. 



Kota, a rust resisting variety of common spring wheat, L. R. Waldron and 

 J. A. Clark (Jonr. Amer. »S"oc. Agron., 11 {1919), No. 5, pp. 187-195, pi. i).— This 

 paper, a joint contribution from the North Dakota Experiment Station and 

 the Bureau of Plant Industry, U. S. Department of Agriculture, describes 

 observations on the yielding ability, rust resistance, and milling and baking 

 qualities of a bearded hard red spring wheat variety designated as Kota 

 (C. I., No. 5878), as compared with durum wheat and with other common spring 

 wheat varieties. Kota is said to have been separated in 1917 from Monad, 

 a durum sort introduced into this country from Russia in 1903 by H. L. Bolley. 



Field observations of pure line selections of Kota are held to indicate that 

 the variety possessed a resistance to the form or forms of stem rust of wheat 

 (Puccinia graminis tritici) present at Fargo, N. Dak., Brookings, S. Dak., and 

 St. Paul, Minn., in 1918, which was decidedly gi-eater than that exhibited by 

 the common spring wheats, and second only to that of the more resistant 

 durum wheats. Data from gi*eenhouse inoculation experiments conducted by 

 E. C. Stakman at the Minnesota Experiment Station and by L. E. Melchers at 

 the Kansas Experiment Station with different biologic forms of the rust are 

 also briefly reviewed. Yield data for the season of 1918 showed an average 

 of 31.92 bu. per acre for six durum varieties, 22.82 bu. for ten common spring 

 wheats, and 29.53 bu. for Kota. Marquis produced 29.33 bu. 



Kota was found to yield somewhat less flour than the average for the wheats 

 examined, while in the baking tests it exceeded the other common spring 

 wheats except Marquis, which it equaled. 



Results of wheat variety and manurial trials, season 1918—19, I, IT, {Jour. 

 Dcpt. Agr. Victoria, 11 {1919), Nos. 3, pp. 158-163; 4, pp. 217-221).— This de- 

 scribes the continuation of work previously noted (E. S. R., 39, p. 540; 40, 

 p. 337). 



The highest yielding varieties of wheat tested at Longerenong were hybrid 

 Gallipoli, selected Federation, and a hybrid strain. Federation X Bobs, with 

 yields amounting to 41.9, 40.3, and 40 bu. per acre, respectively. In a com- 

 parison of a number of hybrid strains with selected varieties, hybrid Gallipoli 

 was again first with 45.8 bu. per acre. 



Rate-of-seeding tests with Federation showed a gradual increase in yield 

 with an increase in the rate of seeding up to 75 lbs. per acre for early seed- 

 ing (May 31) and up to 120 lbs. for late seeding (July 10). In a comparison 

 of early and late seeding for early, mid.season, and late maturing varieties 

 the early varieties yielded better when sown late, but not so well as the mid- 

 season varieties sown at the same time. 



Tests with 8 barley varieties resulted in yields ranging from 55.9 bu. 

 per acre for Kinver to 76.2 bu. for Oregon. 



Additional variety tests with wheat were conducted at Ouyen, Cowangie, 

 and Carwarp in the Mallee area. The leading varieties were Dart Imperial 

 and Tandilla King, each with 21.2 bu. per acre for a 3-year average at Ouyen, 

 Federation w-ith 28.3 bu. for a 4-year average at Cowangie, and Currawa with 

 18.4 bu. for a 3-year average at Carwarp. 



Fertilizer tests with wheat, conducted at various experimental centers, are 

 held to indicate that moderately heavy applications of superphosphate give 

 the best results.
