318 DRY FARMING 



ieties have been distributed tihrough the efforts of the 

 South Dakota Experiment Association until at the pre- 

 sent time nearly all of the crops grown in the state are 

 of adapted varieties. Odessa, S.D, 182 barley can be 

 grown successfully throughout the state. Manchuria, 

 Minnesota 105 is well adapted to the eastern section. 

 Among the oat varieties, Sixty Day S.D. 165 and its 

 selections have proved best and are generally grown. 

 Two medium late varieties are fairly popular, namely, 

 the Swedish Select S.D. 112 and the Silvermine. Durum 

 wheat is represented by Kubanka S.D. 75 and a pedi- 

 greed variety selected from the Kubanka, Acme S.D, 284. 

 Common spring wheat is almost exclusively Marquis or 

 Preston procured from Canada. Swedish S.D. 348 and 

 Dean S.D. 177 and a selection from Dean, the Advance 

 S.D. 1030 are hardy varieties of winter rye. Grimm S.D. 

 162 and common alfalfa grown in South Dakota for a 

 long time are the most commonly grown and best adapted 

 varieties of alfalfa. There is some Turkestan grown, but 

 its popularity has not increased with that of the Grimm 

 and the South Dakota Common. Cossack, a new variety, 

 is proving hardy and becoming popular in some localities. 

 White Spring emmer is the only variety of emmer grown. 

 Tambov S.D. 80 is the best proso and Kursk S.D. 79 or a 

 selection from Kursk known as Shelley S.D. 348 are the 

 best adapted millets. Corn varieties have been intro- 

 duced and developed by corn growers in nearly every 

 section of the state. In the southeastern section A. J. 

 Wimple has developed the Wimple's Yellow Dent, in the 

 northwestern section the late Logan Slaughter has car- 

 ried on the work of selecting and increasing the large 

 strain of Squaw corn known as Slaughter's Squaw com. 

 The Northwestern Dent variety has given a good account
