GROUP II. — 4 VARIETIES. 



Group II consists of four varieties which appear very promising as 

 grain producers. The small size of the seeds is not objectionable, 

 but on the contrary advantageous when grown for grain alone. 



Seeds olive-yellotv; germ yellow — 2 varieties. — Nos. 17852 E, 23312. 

 Seeds black; germ yellow — 2 varieties. — Nos. 17852 B, 23311 A. 



GROUP III. 3 VARIETIES. 



The four or five varieties belonging to Group III have a very dif- 

 ferent appearance from other soy beans. They all come from the 

 valley of the Yangtse, and are said to be grown on the low-lying 

 rice fields either as a green manure or for fodder. Their marked 

 leafiness, large size, and slender stems make them especially desirable 

 for hay. They are too late to mature at Washington. 



Seeds broivn to olive; germ yellow — 3 varieties. — Nos. 9344, 20798, 23336. 

 Seeds black; germ yellow — 3 varieties. — Nos. 6560, 20797, 23337. 

 Seeds bicolored; genu yellow — 2 varieties. — Nos. 6559, 23338. 



GROUP IV. — 76 VARIETIES. 



Group IV is the second largest group and includes the most impor- 

 tant Manchurian varieties. From the standpoint of seed production, 

 they promise to be superior to Group I because of their relatively 

 slender stems, permitting easy mowing, and their smaller pods and 

 seeds, which shatter less easily. They can also be planted more 

 closely because they are less bushy. 



Seeds straw-yelloio; germ yellow— 25 varieties.— Nos. 14954, 16789, 16789 A, 16789 B,
