Dam number. — The " dam number " is the "regis- 

 ter number" of the parent ear and is useful in 

 tracing the pedigree record from year to year back 

 to the source. 



Annual ear number. — In order to designate the 

 . two hundred or more ears selected from the field, 

 each one is given an " annual ear number," which 

 runs in a series from one up to two hundred or 

 more. This number is only temporary, to serve 

 while working on the corn for the final selection of 

 seed ears, and when the seed ears are selected to 

 be planted, each is given a permanent "register 

 number," as explained under that heading. 



If desired, a record may be kept of certain phys- 

 ical and chemical properties, as length, circum- 

 ference and weight of ear and cob, per cent of 

 grain, number of rows of kernels on the ear and 

 the average number of kernels in the row, and per- 

 centage of protein or oil if determined. 



Performance record of field rows. 



The field row or breeding row numbers should 

 correspond, for the sake of convenience, with the 

 register numbers of the ears planted. For example, 

 ear Register No. 101 should be planted in Field 



Row No. 1. The percentage of stand and the yield 

 per acre of each field row should be determined 

 and recorded. 



On the same sheet with the complete year's 

 record of the breeding plot appear the records of 

 the multiplying plot for the same year, and for the 

 next year following, and also the records of the 

 commercial field for the same year and for the next 

 two years. If the record sheet is for the breeding 

 plot for 1905, it is important finally to record on 

 the same sheet the record of the multiplying plot 

 for 1906 and of the commercial field for 1907, 

 and for convenience and comparison it is well to 

 record on the same sheet the yield of the multiply- 

 ing plot for 1905, and the yields of the commercial 

 field for 1905 and 1906. If a breeding plot were 

 started in 1905, the breeder could have both a 

 breeding plot and a multiplying plot in 1906, and 

 a breeding plot, multiplying plot and commercial 

 field in 1907 ; and from the 1907 crop on the com- 

 mercial field he could sell seed corn with a regis- 

 tered pedigree of three years, one year in the 

 breeding plot, one year in the multiplying plot and 

 one year in the commercial field. In 1910, he could 

 sell seed corn from his commercial field with a
