This is the fourteenth year that the Experiment Station has run field tests to 

 determine the trueness to tj^pe of various kinds of vegetable seeds offered for 

 sale in this State. The State Seed Inspector purchased 299 samples of beans, 

 beets, carrots, corn, rutabagas, spinach, and turnips for trial in field test plots 

 in order to compare plant characteristics with the labeled variety name. Plant- 

 ing was done on May 23, 24, 25, and 26 and growing conditions were excellent, 

 except for spinach, for which growing temperatures were too high. Therefore, 

 results for spinach are not recorded in this report. Dry weather did not affect 

 the seed trials as the plots were located in a moist area of the trial grounds. 



Conformity to type was the m.easure of comparison in the tests, and individual 

 plants were called off -type when they could not be classified in a group of plants 

 ranging fairlj' close to the tj'pe generally accepted as typical for the particular 

 variety under consideration. Yield records were not taken nor were replications 

 of plantings made. The large number of lots made this impossible. 



The source of seed is given together with remarks on conformity to type, except 

 that those lots of seed which were tested in the field and found 100 percent true- 

 to-type are not included in this table.
