Seeds were taken from all the pure lines of alfalfa growing at the 

 Evergreen Nursery, anl these plots have been discontinued. Twenty- 

 six plant selections were made from these plots and the seeds from 

 these plants were planted in rows at the Mesa Farm last fall. 



GRAIN SORGHUMS 



As a preliminary test for securing good foundation stock for 

 breeding work with the grain sorghums, sixty head selections of milo, 

 feterita and kafir were planted at the Yuma Date Orchard in July. 

 Approximately one hundred plants were grown from each selection, 

 and the following notes were taken: Date planted, date up, date 

 thinned to one plant in hill, date first head, date full head, date ripe, 

 number of heads per plant, weight of heads from each selection cut 

 not over one and one-half inches below base. These data will be used 

 as a basis for further selection in breeding for higher yielding strains 

 and more desirable types. A total area of one and one-eleventh acres 

 was planted to these selections, and a total yield of 5758 pounds of head 

 grain was obtained.
