Summary
Quality comparisons were made with equal size tubers of the Irish potato varieties Red LaSoda, White Rose, Sebago, and Russet Burbank.
Varietal differences in tuber cell size were found. Russet Burbank tubers contained the largest cells, and Red LaSoda the smallest. White Rose tuber cells were slightly larger than those of Red LaSoda while Sebago tuber cell size was exceeded only by that of Russet Burbank.
There was a significant relationship between specific gravity and cell size of the potato tubers.
Tuber cell size and starch content were highly correlated, indicating that starch content was associated with cell size of tubers. Russet Burbank tubers contained the largest percentage of total starch, while Red LaSoda tubers were of lowest total starch content.
Mealiness scores of tubers were significantly associated with their cell size. Tubers of varieties containing the largest cells were rated highest in mealiness by the taste panel.
