SPEING CEREALS AT MORO, OMKd

In Tabic XIX the spring-barley varieties are arranged in groups 

 of related varieties, showing the 5-year average yield of each variety 

 and the average yield of each group. Typical heads of the leading 

 varieties of barley at the Moro substation are shown in figure 16.

DESCRIPTIONS OP THE BEST VARIETIES. 



The 6-rowed varieties. — The leading 6-rowed varieties, as shown in 

 Table XIX, are Mariout, Coast, Oderbrucker, and Beldi. Heads of 

 the first three varieties are shown in figure 16. 



The Mariout (C. I. No. 261) is an Egyptian variety which is char- 

 acterized by a compact spike of the type often called club, although 

 it possesses this characteristic to a lesser degree than the White Club. 

 The kernel is somewhat coarse and the beard is not always entirely 

 broken off in thrashing. It is an early, heavy-yielding variety in this 

 section. 



The Coast variety (C. I. No. 626) is the common 6-rowed barley 

 grown upon the Pacific slope and in the Columbia Basin. It 

 is called by various names, such as Common California, Bay Brewing, 

 and sometimes Blue barley. The spike is less compact than that of 

 the Mariout, and in many localities the plant is somewhat taller. 

 Like the Mariout, the awn is not entirely removed in thrashing. It 

 is a large-kerneled, heavy-yielding variety. It has been grown for 

 many years in the western United States and probably came origi- 

 nally from Egypt. 



Beldi (C. I. No. 190) is another North African variety, which 

 closely resembles the Coast. It is, however, slightly earlier, and the 

 spike and straw are somewhat shorter.
