POLLINATION AND HYBRIDIZATION. 21 ! 



Previous to 1907 the remarkable uniformity of the plats at the | 



Arlington Experimental Farm, except for occasional and evident \ 



admixtures, had led to the belief that natural hybrids of the soy bean i 



did not occur. In that year the occurrence of certain oddly colored j 



seeds, smoky green, smoky yellow, brown and yellow, etc., in the i 

 bulk seed was noted. These were carefully saved and the resultant 

 rows in 1908 gave diverse progeny, showing that some of the seeds 



at least were hybrids. In 1908 more than a hundred single-plant ; 



selections of supposed hybrids were made and planted in 1909. Some ' 



of the results are indicated in Table V.
