fiscal year covered by this report. As usual, a considerable number 

 of Fanners' Bulletins emanating from this bureau were revised more 

 or less extensively, while many others were reprinted without re- 

 vision of importance but with new covers or title-pages. The num- 

 ber of contributions from this bureau to the Journal of Agricultural 

 Research was 29, or 11 less than during the preceding fiscal year, 

 the reduced number being caused by the suspension of the journal, 

 beginning December 1, 1921. These publications show in consider- 

 able detail some of the activities of the bureau. 



The following statement outlines the work of the bureau not other- 

 wise recorded, summarizing the status of the most significant accom- 

 plishments during the past fiscal year. 



FIELD CROPS. 



WHEAT. 



Extension of imj)i'oved varieties. — Two new wheats developed in 

 the breeding experiments in cooperation with the agricultural ex- 

 periment station of Cornell University have been named Forward 

 and Honor. These now are being grown conunercially, and seed is 

 offered for sale by seedsmen and farmers in Xew York State. A mass 

 selection of the Purplestraw variety developed at the Arlington 

 Experiment Farm is being widely grown in eastern North Carolina 

 and is giving good results. 



Kota. a bearded, hard red spring variet}', discovered in 1918 to be 

 especially resistant to stem rust, was grown in 1921 at 30 experiment 

 stations to determine its value in comparison with adapted commer- 

 cial varieties of both common and durum wheats. During the past 

 three years its resistance to stem rust has proved nearly equal to that 

 of the most resistant durum varieties. The commercial stocks of 

 Kota seed were increased to about 6,000 bushels in 1921, and nearly 

 all of this was sown in 1922. 



Red Bobs, an early variety of hard red spring wheat developed in 

 Saskatchewan, Canada, was first included in varietal comparisons 

 in this country in 1920. In both years it has outyielded all other 

 varieties of hard red spring wheat at the Fergus County substation. 

 Moccasin, Mont., and has produced excellent yields at other points 

 in Montana and Wyoming. Eastward in the Dakotas and Minne- 

 sota, however, it is susceptible to injury by stem rust. 



Karmont is the name which has been given to a high-yielding 

 pure-line selection of Kharkof hard red winter wheat developed co- 

 operatively in Montana. In appearance this variety is identical 

 with Kharkof. but it has significantly outyielded it in experiments 

 in Montana. The seed was increased in 1921, and a small commer- 

 cial distribution was made in Montana. 



Hard Federation and Federation, two varieties of white wheat 

 introduced from Australia by this department, continue to give 

 good yields in the Pacific coast area. Hard Federation is unusually 

 well adapted to the dry lands of Oregon and California, where it 

 outyields such improved commercial varieties as Early Baart and 

 Pacific Bluestem. Federation has given high yields under irriga- 

 tion in eastern Oregon and southern Idaho in the last three or four 

 years. At the substation at Aberdeen, Idaho, it has outyielded the
