STUDIES ON OAT BREEDING. 155 



inches in height. The leaves are medium in width, of a dark 

 green color. The grain is long and plump. 



The second sub-group of medium white oats is characterized 

 by larger and more plump grains A typical variety is the 

 Swedish Select. Other varieties belonging in this group are the 

 Banner, Siberian, Abundance and President. 



The Szvedish Select has been a very popular variety in this 

 country. It has rather weak, coarse straw, averaging 40 to 42 

 inches in height. Its leaves are of medium width and dark 

 green in color. The grains are large and plump. The kernels 

 are considerably shorter than the glumes giving the grain in 

 many cases a peculiar notched appearance. 



The Regenerated Szvedish Select is the same oat to which the 

 so-called regenerating process has been applied by the Garton- 

 Cooper Seed Company. The method by which this regenera- 

 tion is secured is to cross fertilize two plants of the same vari- 

 ety. The oat flower is normally always fertilized by its own 

 pollen. That is, it is very closely inbred. If this self-fertihza- 

 tion is prevented and the flower fertilized with pollen from 

 another plant it is claimed to produce a more vigorous strain. 

 This variety shows the same characters as the Swedish Select 

 except perhaps slightly larger grains. 



The Banner and Siberian present practically the same char- 

 acters. Both have stiff, medium coarse straw from 40 to 44 

 inches in height. The leaves are rather broad and dark green in 

 color. The grains are plump, medium sized and well filled. 



The President oat was introduced to the trade in 1908 by the 

 Garton-Cooper Seed Company and was called "Carton's New 

 Breed of White Oats'" It is claimed to be especially adapted 

 to "hot, dry and otherwise unfavorable conditions." In our 

 experience the straw is large and coarse, averaging 38 to 42 

 inches in height. The leaves are broad and dark green in color. 

 The grains are very large and plump. 



MEDIUM LATE VARIETIES WITH YELLOW GRAIN. 



The Gold Rain variety would belong to the first of the two 

 sub-groups given above in respect to type of grain. However, 

 its yellow color removes it to a different class. This oat was 

 produced at Svalof, Sweden, as a pedigreed selection from the
