same variety should be secured from different sources, having 

 enough from each to make the general planting the following 

 year in case it proved satisfactory. Having secured the seed, a 

 germination test should be made of each to determine its value in 

 this respect as well as to obtain an index to the rate of sowing. 

 This germination test will probably show some variations within 

 strains, while the vigor of the seedlings will also probably vary 

 as may be seen by Fig. 376.

Variation in Germination of Jersey Wakefield Cabbage 

 Seed 



When the field planting is made, fifty plants will be sufficient. 

 As they approach maturity, a study of the respective strains will 

 show differences regarding general type, time of maturity, solidity 

 of head and general productiveness. In order to secure accurate 

 data, weighings should be made of the heads of the respective 

 strains. The following table shows the variability of six strains 

 of Jersey Wakefield cabbage grown the past season, each of which 

 was purchased from a seedsman of good reputation.
