20 SOY BEAN VARIETIES. 



S. P. I. No. 9344, from China, has very similar seeds, rather plumper, and much dis- 

 colored, but with more dark color than in the variety just described. The black is 

 usually massed as a saddle around the eye and extending outward over about half or 

 more of the surface. This serial number has not been tested by the writer, and its 

 characteristics are not known. 



The name is derived from the city of Hankow.

MEYER. 



S. p. I. No. 17852 is a recent importation from China, seciu-ed by Mr. F. N. Meyer. 

 From the seed alone it is certain that this is a distinct variety of the mottled group. 

 The seeds are plump and shiny, l^roadly elliptical, 6| to 8 mm. broad, 7 to 10 mm. long, 

 the ground color deep brown, with patches or blotches of black on either side near the 

 hilum and eccentric curved lines or stripes of the same color near the dorsal edge. 

 The amount of this black color is quite variable, some seeds being quite covered with 

 it and some showing only faint lines of it . 



Green-Seeded Group. 



SAMAROW. 



Samarow is a dwarf early variety of unknown origin. It has been sold for several 

 years by J. M. Thorburn.tfe Co., New York, under the name Green Samarow. It may 

 readily be distinguished from all other varieties by the elongated, flattened, light-green 

 seeds, quite different in shape from those of any varieties which are similar in color. 



The stems of the Samarow variety are slender, one-eighth to one-fourth inch in thick- 

 ness at the base, 10 to 24 inches tall, well branched with short l)ranches, the lower ones 

 only 4 to 5 inches long, ascending or spreading; leaves broad but not large, generally 

 very dark green. The stem and branches are thickly set with medium-sized pods, 1\ 

 to 1| inches long by one-fourth to one-third inch wide, 2 to 4 seeded; often one-half of 

 the pods on a plant will contain 3 seeds each, which is a higher proportion than has been 

 •observed in any other variety, while pods containing 4 seeds each are not uncommon. 

 The seeds are elliptical, distinctly elongated, or some almost reniform (kidney-shaped), 

 5 to 6i mm. wide by 7 to 9 mm. long, dull to faintly shining, very pale green or pea 

 green in color. The variety may be easily recognized by the elongated, pale green 

 seeds, the only other elongated seeds being black or mottled. 



The Samarow soy bean requires from ninety to one hundred and five days to come 

 to full maturity, the average being about ninety-five days. It is a fair to good yielder 

 of seed and it is for this purpose that it is likely to be grown. The yields reported run 

 from 5 to nearly 15 bushels per acre. The small size of the plants makes it unprofit- 

 able to grow for forage production, but the alnmdant crop of pods, containing 3 seeds 

 commonly and 4 occasionally, suggests the possibility of breeding for high seed yields.

GUELPH. 



The Guelph is one of the oldest and best known of the varieties in cultivation. For 

 many years it has been sold by numerous seed houses as Early Green, Medium Green, 

 and ]>iledium Early Green. It is a rather curious fact that during the eight years in 

 which the United States Department of Agriculture has been actively engaged in the 

 introduction of oriental legumes it has but once secured this variety. This is prob-
