individual that has been propagated by slips, and by growing seed from these 

 rows we are merely growing so many seedlings from the original selected 

 plants. The number of seedlings to be grown from each row should 

 depend on the time that the grower has to give to the work and on the 

 emphasis that he desires to place on his breeding. Here, as in all other 

 breeding work, the larger the number of individuals used, the better. 

 The writer would advise that not less than 300 to 500 plants be grown from 

 seed of each of the select rows. These seedlings should be cared for as in 

 the case of the first plants grown, and in early September they should be 

 planted in a seedling test plat, following the methods outlined in paragraph 3 . 



When these plants reach the second crop year they should be examined 

 and a few of the best individuals selected as in the case above, paragraph 5. 

 These selected individuals should be dug up at the proper time and clonal 

 test plats planted, as described in paragraph 6. From these clonal test 

 plats the best rows should be selected, as in paragraph 8, and broadcast 

 field test plats grown, and the seed multiplied as in the case of the first 

 selections (paragraphs 9 and 10) until sufficient seed for growing large 

 areas has been obtained. 



A careful study of the method of breeding timothy outlined above, 

 considering the length of life of the plant, will reveal that the extra trouble 

 and work required are much less and really simpler than are required by 

 the methods of corn selection advocated for farmers, which are being 

 extensively used in some States. This method is the direct outgrowth 

 of the experiments that have been conducted at Cornell, and has thus 

 been thoroughly tested in practically every feature. 



In making such selections as are outlined, it would be well, so far as 

 possible, always to do what one can to get at least one early- and one late- 

 maturing type in order that the harvest may be better controlled.
