The Production of New and Improved Varieties of Timothy 363

 the isolation of the various types and by inbreeding, many of them are 

 found to transmit their characters and are thus to be considered as dis- 

 tinct races.

"VVe have described above the process by which a considerable number 

 of new timothy varieties have been produced. When grown in rows,

one plant in a place, some of these varieties gave very large yields 

 in comparison with other varieties and would seem to be of value 

 (Fig. 93). The practical grower, however, will immediately inquire 

 whether these qualities or differences in yield are shown when the 

 various sorts are grown in the ordinary way by broadcast sowing; for 

 of what value are they unless their good qualities are maintained 

 under ordinary methods of culture? 



Seventeen of the new types were selected for trial and plats were 

 sown with open-fertilized seed. The seed was taken from rows of these 

 varieties propagated from bulbs and, while not isolated, they were very 

 much less subject to crossing than when one plant of a new type stands 

 alone in a mixed field. The later experience with the plats grown from this
