following table, the records of the average yield per plant by clonal 

 propagation in ten light-yielding and ten heavy-yielding rows will give an 

 indication of the differences between the various types in this one 

 important character. (See Table i, column headed " Average yield per 

 plant of mother by clonal propagation.")

These tests were made with 16 plants from each individual, the different 

 rows being placed 4 feet apart and the plants 3 feet apart in the rows. 

 The plants in each row, coming from a single individual and propagated 

 as clons, would naturally be expected to show great uniformity, but in 

 no other method of testing are the characters of the individual brought 

 out so distinctly. Among the 200 types there were no two rows that 

 could not be separated one from another by some one or many distinctive 

 characters. It would have been possible to construct a botanical key
