TESTS OF SELECTIONS OF OATS. 21 



OHIO, i 



The tests at the Ohio Agricultural Experiment Station at Wooster 

 have been quite extensive. Forty-seven of the selections were sent 

 to Prof. C. G. Williams, agronomist, in 1908, and 62 were added to 

 the tests the following year. These 109 selections represented the 

 various series as follows: Series 8, 7 selections; series 27, 1; series 30, 

 5; series 31, 4; series 33, 8; series 34, 11; series 38, 1; series 42, 1; 

 series 44, 1; series 48, 4; series 49, 27; series 50, 16; series 51, 3; 

 series 62, 13; series 63, 3; series 132, 1 ; series 137, 2; and series 165, 1. 

 The first test of these selections was made in duplicate in rows 17 

 feet long and 1 foot apart. Later tests of the more promising strains 

 were made in hundredth-acre plats, a few of the best going finally 

 into the regular varietal test in tenth-acre plats. 



In 1908 four of the 10 highest yielding strains were of series 50, 

 Sixty-Day X Probsteier, two were of series 49, Sixty-Day X Clydes- 

 dale, and two were of series 62, pure lines of Sixty-Day. The high- 

 est yield of all, however, 85.08 bushels to the acre, was obtained from 

 8cl-5-4, a selection from the hybrid Danish Island X Asia Minor 

 Rustproof. Selections 50al-24 and 50al-15 from the hybrid Sixty- 

 Day X Probsteier yielded 80.02 and 78.13 bushels, respectively. The 

 highest yields obtained from pure lines developed at the Ohio station 

 from three commercial varieties were as follows: Sixty-Day, 86.54 

 bushels; Siberian, 80.51 bushels; and Improved American, 81.2 

 bushels. 



The highest acre yields produced by the selections from the Office 

 of Cereal Investigations in 1909 were obtained- from 50al-15, 83.24 

 bushels; 50al-21, 72.31 bushels; 50al-24, 69.96 bushels; and 8cl-5-4, 

 69.96 bushels. The other six high-yielding strains from the 1908 

 tests yielded from 60 to 66 bushels each. The yield of 50al-15, 

 83.24 bushels to the acre, was higher than that of any other variety 

 tested in hundredth-acre plats in 1909. 



In 1910 four strains from the Office of Cereal Investigations were 

 grown in tenth-acre plats and 24 in hundredth-acre plats. The yields 

 of the four strains in tenth-acre plats were as follows: 50al-15, 63.64 

 bushels to the acre; 50al-21, 56.25 bushels; 50al-24, 74.11 bushels; 

 and 8cl-5-4, 77.12 bushels. The only varieties from other sources 

 which exceeded 8cl-5-4 in yield were Storm King, 79.3 bushels, and 

 a selection from Siberian, 77.86 bushels. The average yields of the 

 four strains just mentioned for the three years 1908, 1909, and 1910 

 were as follows: 8cl-5-4, 77.4 bushels; 50al-15, 75 bushels; 50al-24, 

 74.7 bushels; and 50al-21, 67.6 bushels. Of the 24 strains grown in 

 hundredth-acre plats in 1910 the best yields were produced by 

 34al-ll-2-l and 34al-ll-2-3, 98.44 bushels to the acre each; 



i These tests were made by Prof. C G. Williams, to whom acknowledgments are due for the results 

 here reported.
