TYPE AND VARIETY STUDIES OF VEGETABLES 



Conducted by the Seed Laboratory 



Waldo C. Lincoln, Jr., Laboratory Assistant 



Under the Supervision of W. H. Lachman, Assistant Research Professor 



Department of Olericulture 



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

 determine the trueness to type of various kinds of vegetable seed offered for sale 

 in this State. The State Seed Inspector purchased 317 samples of beans, beets, 

 broccoli, cabbage, carrots, corn, radishes, rutabagas and turnips for trial in 

 field test plots in order to compare plant characteristics with the labeled variety 

 name. Planting was done June 12, 13 and 14 and growing conditions were good 

 throughout the tests. 



Conformity to type was the measure of comparison in the tests, and individual 

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

 ranging fairly close to the type 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 per- 

 cent true-to-type are not included in this table.
