seed. Tliis seed has been distributed not only among the farmers 

 in the Judith Basin, but in other parts of the State as well. Reports 

 obtained from farmers who are growing this variety in different 

 parts of Montana indicate that they consider it better than other 

 similar varieties. Some farmers claim that the Kharkof yields 

 from 5 to 10 bushels more than any common strain of Turkey wliich 

 they had been growing. 



The average dates of seeding, heading, and maturity, the height, 

 yield per acre of grain and of straw, and weight per bushel of the 

 seven leading varieties of winter wheat are given in Table XII.

 wheat varieties at the Judith Basin substation. Moccasin, Mont., in seven years, 1909 

 to 1915, inclusive.

 Varietal Experiments in Nursery Rows. 



The nursery work with winter wheat at the Judith Basin sub- 

 station has included the testing of new varieties and strains and the 

 making and testing of selections. New varieties are usually grown 

 in nursery rows, in order to determine their hardiness and something 

 of their yielding powers before they are tested in plats. 



In 1909 a large number of head selections were made from some 

 of the best varieties. These were sown in head rows and the most 

 promising were saved and sown in increase rows in 1910. Additional 

 selections were made in 1910 and 1911, partly within the pure lines 

 and partly from the mass varieties. In every case the selections 

 appearing most promising the next year were saved and grown 

 again. 



In 1912 various selections were grown in hundredth-acre plats, 

 8-rod rows, and in head rows. The hail that year almost completely 

 destroyed the winter-wheat nursery. No yields could be determined, 

 though some plants survived the had. From the records of previous 

 years it was possible to determine which were the most promising 

 selections. Some seed of these was obtained from surviving plants 

 and sown that fall. Most of the selections had then been grown long 

 enough to determine which were the most promising. Since that
