L04 SOY BEANS IN BENGAL, BIHAR AND ORISSA. 



darker bullate leaves and a more prostrate habit. At harvest 

 time a limited number of single plants were selected with a view 

 to further Botanical study. In the spring of the following year 

 the interest taken in the Soy Bean crop elsewhere encouraged us 

 to examine the chemical composition of these three types, and it 

 was found that there was a marked difference in the proteid 

 content of the types, the variation in the nitrogen content of 

 the samples of each type being less than the differences between 

 the means of the tj^pes. 



In 1910, the seed of the single plants which had been 

 analysed was sown together with some samples obtained by 

 Mr. A. C. Ghosh from the Kurseong bazar and some more 

 samples of the types already obtained from the plains. The 

 seed of the original plots was also resown for further study. 

 Acclimatised seed of two American varieties, Barchet and 

 Riceland, were obtained from Saharanpur and sown for com- 

 parison with the local varieties. As a result of the year's work 

 a distinctly earlier black seeded form was obtained from a plot 

 (E 256 of 1910) grown from seed collected at the Bankipur 

 Exhibition. The trial plots of the seed from Kurseong failed. 

 More attention was paid to the chemical selection work and 150 

 single plants of each of the three types grown in th previous 

 year were analysed for nitrogen and oil. The seed of each single 

 plant derived from the seed of the original single plan 

 the previous year was again analysed. These analyses confirmed 

 our conclusions of the previous year and showed us that the 

 percentage oil content was also an inherited character. 



In 1911, the seed of a number of the single plants analysed 

 in the previous year was sown, and the seed of all the plants 

 of' each of the original selections was bulked and that 

 derived from each of the original selected plants was again sown 

 separately. These plots have again been analysed and confirm 

 our original conclusions. In addition, the success of the plots 

 of the acclimatized American varieties induced us to exchange 

 seeds of the Bengal types with Mr. Piper, of the United States 

 Plant Industry Bureau, who kindly supplied us with seed of the
