TABLE 8. PHYSICAL SELECTION OF POTATOES FOR TABLE QUALITY 



From fifty to one hundred tubers were used in making each of 

 these selections, all of which were grown on the same type of soil, 

 (a light sandy loam), in a single acre plot. In making selections it 

 was very noticeable that there was a great varietal difference in 

 quality. As the table shows, in some varieties it was very easy to se- 

 lect tubers of good cooking quality, while in other varieties no sharp 

 distinctions could be made. In Rust Proof, Ionia seedling, Twen- 

 tieth Century, Gold Coin and Early Manistee no potato of good 

 quality could be found although there were a number classed as 

 medium. This is perhaps due to the fact that this was the first year 

 any of the stock had been grown in Connecticut and they may not 

 have been adapted to the particular kind of soil on which they were 

 rrrown. I have learned that all of these varieties except Rust Proof 

 sometimes are of fair quality in other places. 



It seems evident from Table 8, that this anatomical difference 

 is a varietal character, the difference between varieties being very 

 great. The difference in quality within the variety, however, with 

 as similar environmental conditions as it was possible to give, is 

 almost as great as the difference between varieties.
