TESTS OF SELECTIONS OF OATS. 



oats, a yield of 1 ounce from one of these rows is at the rate of 5 

 bushels to the acre. Similarly, the rate of seeding is easily calcu- 

 lated; at the rate commonly in use in the corn belt, 2.5 bushels to 

 the acre, one-half ounce of seed is required for each row. 



RESULTS OF THE TESTS. 



The tests at McLean in 1907 included 419 selections from hybrids 

 and 82 pure-line selections from commercial varieties. In 1908, 378 

 hybrids and 69 pure-line selections were grown. Only 177 of the 

 selections from hybrids and 51 of those from commercial varieties 

 were grown both years. Table I summarizes the tests of these two 

 years, the strains being grouped and averaged according to their 

 parentage. Tins table shows the number of strains of each series 

 which were grown each year and the number which were included 

 in both years' tests, with the average yields in bushels to the acre.
