1 The original strain, Seed and Plant Introduction No. 5938, is grown elsewhere under Cereal Investiga- 

 tions No. 165. 



2 Plant Breeding No. 1571. 



In 1911, several, representative unselected commercial varieties 

 were added to the experiments at Cornell University, which previous 

 to that time had included mostly pure-line selections from hybrids 

 and from commercial varieties. Among these were Sixty-Day, 

 Silvermine, and Lincoln. The unselected Sixty-Day yielded so much 

 less than the selection 5938-1 that it was discarded at the end of 

 three years, but the other two varieties are still included. The 

 7-year (1911-17) average yield of the Silvermine is 60.3 bushels; of 

 the Lincoln, 57.3 bushels; and of the Sixty-Day selection (5938-1), 

 53.8 bushels. 



Results in Pennsylvania. 



The Pennsylvania Agricultural Experiment Station at State 

 College (15) has included the Sixty-Day variety in its experiments 

 since 1907 and the Kherson variety since 1909. The results to and 

 including 1910 have been published. The annual and average yields 

 of these and seven other varieties in two or more years of the 4-year 

 period from 1907 to 1910, inclusive, are shown in Table V. 



As shown in Table V, the Sixty-Day oat during the 4-year period 

 from 1907 to 1910, inclusive, outyielded all others at State College. 

 The 2-year data on the Kherson indicate that it will do equally as well 

 as the Sixty-Day in central Pennsylvania. 



No data on oat varietal tests have been published by the Penn- 

 sylvania station since 1911, but Prof, C. F. Noll, associate professor 

 of experimental agronomy, has kindly summarized the more recent
