PLATE 5 
Green Mountain tubers which sprouted in the storage cellar in the spring. 
A. —Tubers 75, 76, and 77 illustrate a condition, frequently observed, in which there 
is one apparently normal sprout at the bud end, the remaining sprouts being more or 
less spindling. All hills from these tubers showed leafroll or combined leafroll and 
mosaic symptoms. 
B. —Tubers 78, 79, and 80 with normal sprouts clustered at the bud ends. Tuber 78 
produced mosaic plants while 79 and 80 gave plants entirely healthy throughout the 
season. 
C. —Tuber 81 produced healthy plants; 82, very weak plants showing both leafroll 
and mosaic (note the spindling sprouts toward the stem end); and 83, mosaic plants. 
D. —Tuber 84 with normal sprouts produced medium mosaic hills, while tubers 85 
and 86, with spindling sprouts, produced very weak plants showing leafroll symptoms..
