TWO NEW VARIETIES ADAPTED TO CALIFORNIA.

milling test of the 1909 crop of the Fretes was made by the Oakdale 

 Milling Company, Oakdale, Cal. This test indicated that the Fretes 

 milled easily. It also possessed a 40 per cent wet-gluten content as 

 compared with the Australian samples received and tested by the 

 company, which contained from 10 to 38 per cent of wet gluten. 



PURE SEED OF THE CHUL AND FRETES VARIETIES. 



From the foregoing facts there can be little doubt that the improved 

 types of the Chul and Fretes varieties are of great value to California. 

 Much care, however, should be exercised by the growers in securing 

 pure seed. 



It is reported that Chul wheat is being grown in quantity by a few 

 farmers in the Sacramento Valley from seed introduced into California 

 by the United States Department of Agriculture in 1903. It is also 

 reported that this wheat is used to good effect in blending with the 

 common wheats in the production of flour. Samples of the 1909 crop, 

 which have been received, show that this wheat is mixed with other 

 varieties. This is probably due to lack of care on the part of growers 

 in keeping the variety pure. This mixture is an inferior grade of seed 

 and is not desirable for the farmer wishing to start with pure seed of 

 the Chul variety. 



The Office of Grain Investigations of the Bureau of Plant Industry 

 can usually supply small quantities of pure seed of these and other 

 varieties. 



PROTEIN CONTENT AS AFFECTED BY TIME OF SEEDING. 



Observations in California indicate that the length of the growing 

 and fruiting periods of a variety of wheat controls, to a considerable 

 degree, the percentage of protein contained. Long growing and 

 fruiting periods produce grains lower in protein content than short 

 growing and fruiting periods. An effort was made during the past 

 year to determine the effect of the length of these periods upon the 

 protein content of the Chul and Fretes varieties sown early and late. 

 The results obtained arc given in Table III.

of the Chul and Fretes wheat varieties. 



a The percentages of protein were obtained by multiplying the percentage of nitrogen by 5.7.
