RESACA (RED RESACA). 



Description. — Plant spring habit, midseason, midtall; stem purple, weak to 

 midstrong; spine awnless, fusiform, narrow, middense, inclined; glumes gla- 

 brous, brown, midlong, narrow; shoulders narrow, oblique to square; beaks 

 midwide, obtuse, 0.5 mm. long; apical awns few, 2 to 15 mm. long; kernels red, 

 short, soft, ovate; germ small; crease midwide, shallow to middeep; cheeks 

 rounded ; brush midsized, short. 



This variety is very similar to Odessa except in having a spring habit and 

 purple straw and in being slightly earlier. 



History. — The origin of Resaca wheat is not known. The sample described 

 was obtained from C. P. Warner, Lake Victor, Tex., in 1919. He wrote as 

 follows : 



The pure Red Resaca was introduced in this county (Burnet County, Tex.) 

 some 30 years ago by S. W. Shelburne, and has not been grown extensively. 

 It perhaps does not produce as much as the Mediterranean. 



Distribution. — Grown in Burnet County, Tex. 



Description. — Plant spring habit, midseason to late, tall ; stem white, strong ; 

 spike awnless, fusiform, lax, erect, shatters; glumes glabrous, brown, midlong, 

 narrow ; shoulders wanting to narrow, oblique ; beaks narrow, sometimes want- 

 ing, usually acute, 0.5 mm. long ; apical awns few, 3 to 10 mm. long ; kernels red, 

 short to midlong, semihard to hard, ovate; germ midsized; crease midwide, 

 shallow to deep, triangular ; cheeks angular ; brush midsized, midlong. 



This variety differs from all other varieties of brown-glumed awnless winter 

 and spring, red-kerneled wheats in having semihard to hard kernels. 



History. — The Stanley originated about 1895 from the progeny of a cross made 

 by Dr. William Saunders, Dominion cerealist, Ottawa, Canada. " The Stanley 

 is a twin wheat with the Preston, both having had origin in the one kernel " 

 (169, p. 14). "Parentage Ladoga (female) crossed with Red Fife (male) " 

 (164, P- 219). An awned, white-glumed, white-kerneled winter wheat also has 

 been grown under the name Stanley (204, P- 38). 



Distribution. — Grown under irrigation in the Gallatin Valley of Montana and 

 experimentally in Minnesota. 



SILVERCOIN. 



Description. — Plant winter habit, midseason, short to midtall; stem white, 

 strong ; spike awnless, clavate, dense, erect to inclined ; glumes pubescent, white, 

 midlong, midwide; shoulders midwide, oblique to square; beaks wide, obtuse, 

 1 mm. long; apical awns few, 3 to 10 mm. long; kernels white, short to mid- 

 long, soft; ovate to oval; germ midsized; crease midwide, middeep; cheeks 

 angular to rounded; brush midsized, midlong. 



Spikes, glumes, and kernels of Silvercoin wheat are shown in Plate XXXI, A. 



History. — According to Mr. M. L. Peterson, Mendon, Cache County, Utah, 

 Silvercoin wheat originated in a dry -land field of mixed Goldcoin and Sonora, 

 belonging to Eph. Hansen, a few miles from Mendon, about 1900. The wheat 

 was selected, increased, and distributed and became known as Eph. Hansen 

 wheat, but the name later was changed to Silvercoin, though when and by 

 whom is not known; The variety probably is the result of a natural field 

 hybrid between Goldcoin and Sonora. 



Distribution. — Grown in Boxelder and Cache Counties, Utah.
