FIELD EXPERIMENTS IN I915. 



II 



These new varieties have not been given names but bear the 

 number by which they are known in our records prefixed by 

 the word "Maine." 



The 12 pure lines mentioned above were again tested in 191 5. 

 Each pure line was planted in four 1-40 acre plots placed in 

 different parts of the field. The average of the 4 plots was 

 taken as the yield of that pure line. 



The table that follows gives the yields for 191 5 and the aver- 

 age yields for the past three years.

It will be noted that the average yields of these pure lines 

 run remarkably even. The highest yielded at the rate of 83 

 bushels per acre and the lowest at the rate of 74 bushels. This 

 uniformity in yield is probably to be expected when it is remem- 

 bered that these 12 pure lines represent the best out of 350 

 originally selected plants. The average for these 12 pure lines is 

 79 bushels per acre, while the average of 11 of the best com 

 mercial varieties obtainable grown under the same conditions 

 was only 73 bushels. : 



While there is little to choose between these different pure 

 lines, Maine No. 340 has shown some points of superiority. In 

 the first place it is particularly high in yield. In 1914 it averaged 

 109 bushels per acre. This year it gave 83 bushels. Its average 

 for the three years which it has been tested is 884 bushels. It 

 is a selection out of the Irish Victor variety and this year gave 

 a yield of over 8 bushels more than the parent variety. Further- 

 more it has a particularly strong straw and even under the severe
