small seed. 



By growing selected lots of large and small radish seed., 

 Mr. B. T. Galloway (19) found that the large seeds germinated 

 more quickly and with more certainty and produced marketable 

 crops sooner and more uniformly than the small seeds. The lat- 

 ter, however, gave proportionally larger plants. He submits 

 the suggestion that the radish has "been cultivated for the root 

 and selection has been made continually with the development 

 of the root in view without attention to the seed and says 

 that if more nutrition is utilized in root development with 

 plants of equal vigor, less would probably remain for seed 

 development, resulting naturally in small seed. 



The reasoning in this case, however, does not appeal to 

 the writer of this thesis as it would seem that the very fact 

 of a large uvuolus being present would result in better seed 

 if the conception of its function as a storage organ for the 

 production of seed is correct. Rather the answer must be 

 looked for in some natural tendency if it should always prove 

 to be the case that large seed gives small root development. 

 It is not at all uncommon to find that some undesirable quality 

 is emphasized Just as rapidly as the desired one when selection 

 is practiced in animal breeding, and selection for root alone 

 might result in small seed merely according to the chances 

 in selection. 



In experiments with wheat, barley, oats and sugar beets 

 Lubanski (20) reports that the results show the influence 

 on yield and to some extent on quality of crop was in favor 

 of large seed.

 ments (21) with wheat, oats and barley during a five to eight
