ORCHARD-GRASS, OAT-GRASS, BROME-GRASSES 203 



istics. Numerous strains have been selected by Leckenby, 

 by Evans and by Dillman of the U. S. Department of 

 Agriculture, by Keyser of the Colorado Experiment 

 Station and others. As yet no pure strains have become 

 established. 



The progeny of some individuals is quite uniform; 

 in others, very diverse. Keyser has selected 121 distinct 

 strains, and has recently published illustrations and notes 

 on the most striking. The individual plants vary in 

 vigor, height, number of culms, amount of stooling, 

 coarseness of stems, color of leaves and panicles, length and 

 breadth of leaves and earliness. For pasture purposes 

 the most desirable type is apparently one that stools 

 vigorously and produces an abundance of leaves. For 

 hay purposes, one that is relatively bunchy with tall, 

 leafy culms is probably best.
