P. P. Deherain (10) reports a slightly "better yield of 

 wheat from large seed and he and Dupont (11) are cited as 

 reporting yields from large and small kernels of a number 

 of varieties of wheat to have been in all oases in favor 

 of the large kernels, "but a large difference in yield was 

 obtained only when there was a marked difference in the weight 

 of the kernels. 



Soule and Vanatter (1) of the Tennessee Experiment 

 Station conducted experiments for three years in which 

 large and small wheat kernels were separated by means of selves, 

 after the first year each grade being selected from wheat 

 grown from a similar grade. A check plot of unseleeted 

 seed was planted. 



"The average difference in yield at the end of three 

 years between large grains (689 per ounce), and small grains
