ELIMINATION OF VARIETIES. 



A passing glance through the preceding tables will reveal the fact that 

 varieties have been dropped as rapidly as the experimenter could be satis- 

 fied of their inferiority.'' 



Of the 140 lots of seed that have been received, only 31 of them were 

 under test in 1917. There was no question about those that showed them- 

 selves inferior in the plant-row series. There is little question about the 

 desirability of the lowest producers after one year's yield testing. A third 

 set has been dropped after two years of yield testing. But when it comes 

 to the better varieties, one needs at least three year's results for reliable 

 figures' on yielding ability. Four of the strains listed in Table V have 

 been in the variety series for nine years, and all except four of them have 

 been in the yield series at least four years. 



' The last strain of the following varieties were dropped in 1913 : Swedish Select, Minne- 

 sota No. 6, Kherson, Silver Mine, Improved Scotch, Tartarian, Sensation, Improved Banner, 

 2 side oat varieties. Regenerated Swedish Select, Canadian Banner, Dodge, Spanish Lincoln, 

 Mezdag, Bucuim, New Johnson, Giant Ligowo, Johnson, Lawrence, and Jewett's Clydesdale. 



The following varieties were discarded in 1914 : Garton No. 436, Garton No. 396, S. P. 1. 

 No. 226,885, European Hulless, S. P. I. No. 25,749, and Steuben. 



The following varieties were discarded in 1915 : Henderson's Clydesdale, Harrison's, New 

 Market, S. P. I. No. 25318, Great Mogul, Beardsless Propsleir, Golden Rain, Victory, White 

 Ligowa, Vogel, Parsons, and four varieties from an Illinois Seed Company. 



No further varieties were dropped from the variety series in 1916, and only four more in 

 1917, but Most of those in Table V that have not been distributed were dropped in 1918. 

 Those dropped in 1917 were : S, P. I. Nos. 25,591, 25,849, 25,850, and English Wonder.
