74 THE SOY BEAN ; HISTORY, VARIETIES, AND FIELD STUDIES. 



25438 B. A selection out of the original seed. Plants slender, erect, the tips twining; 

 height 36 to 40 inches; very late; pubescence both gray and tawny; 

 flowers white; pods medium-sized, 1^ to If inches long, compressed, 

 scattered, shattering little; seeds straw-yellow, medium-sized, 7 to 7J 

 mm. long, elliptical, slightly flattened; hilum seal-brown; germ yellow. 

 Grown one season. 

 25468. Wisconsin Black. From L. L. Olds Seed Company, Madison, Wis., 1909, 

 secured by that company from the Wisconsin Agricultural Experi- 

 ment Station. Plants stout, erect, bushy; height 16 to 20 inches; me- 

 dium; pubescence tawny; flowers purple; pods medium-sized, IJ to If 

 inches long, compressed, half crowded, shattering little; seeds black, 

 medium-sized, 8 to 8§ mm. long, elliptical, much flattened; hilum pale; 

 germ yellow. Grown nine seasons. This variety has proved to be one 

 of the earliest growing in Wisconsin. While the records are somewhat 

 incomplete, it is almost certainly the direct descendant of S. P. I. 

 No. 5039, received from Vilmorin-Andrieux & Co., Paris, France, 1900. 



27498. From Peking, Chihli, China, 1909. Plants slender, erect, the tips twining; 



height 42 to 48 inches; late; pubescence gray; flowers both purple and 

 white; pods medium-sized, Ij to If inches long, tumid, half crowded, shat- 

 tering little; seeds chromium green, medium-sized, 7 to 7^ mm. long, ellip- 

 tical, slightly flattened; hilum black; germ green. Grown one season. 



27499. From Ingang, Fukien, China, 1909. Plants slender, erect, the tips twining; 



height 36 to 42 inches; very late; pubescence tawny; flowers purple; 

 pods scattered; seeds straw-yellow, 5J to 6 mm. long, elliptical, slightly 

 flattened; hilum seal-brown; germ yellow. Grown one season. 



27500. From Shanghai, Kiangsu, China, 1909. Plants stout, erect, bushy; height 26 



to 32 inches; very late; pubescence tawny; flowers purple; pods medium 

 large, 2 to 2 J inches long, compressed, half crowded, shattering little; 

 seeds straw-yellow, medium-sized, 7 to 7J mm. long, ellijitical, much 

 flattened; hilum light brown; germ yellow. Grown one season. 



27501. From Shanghai, Kiangsu, China, 1909. Plants stout, erect, bushy; height 



36 to 42 inches; very late; pubescence tawny; flowers purple; pods large, 

 2J to 2f inches long, compressed, scattered, shattering little; seeds olive- 

 yellow, cloudy, large, 9^ to 10 mm. long, elliptical, slightly flattened; 

 hilum black; germ yellow. Grown one season. 



THE BEST VARIETIES OF SOY BEANS. 



It is difficult to determine the best soy-bean varieties out of those 

 tested, not only on account of the very large number, but also owing 

 to the divergent results reached at the various places where they 

 have been grown. The soy bean seems to be peculiarly subject to 

 fluctuations brought about by change of soil or change of climate. 

 The differences in behavior of the same pedigreed seed in different 

 places is often very striking, so much so that it is difficult to believe 

 that it is the same variety. Whether these differences are due 

 mainly to climate or to soil is difficult to determine, but in general 

 the results indicate that both factors are potent. On this account ■ 

 it may very well be that the final conclusions reached by experi- 

 menters as to the best varieties will depend upon the place where 

 the experiments have been conducted. The list of the best varieties
