Abstract

Heat inactivation of leafroll virus in tuber tissues of three potato varieties (Russet Burbank, Katahdin, and Mohawk) was studied. Russet Burbank did not tolerate high constant temperatures and a low proportion of tubers and eye-pieces survived the treatments. On the other hand, Russet Burbank eye-pieces survived, with few exceptions, treatment at 40 C for four hours alternating with room temperaure (16–20 C) for 20 hours daily for as long as eight weeks. Inactivation of the virus was complete after six weeks of this treatment. Results obtained with the Katahdin and Mohawk varieties in similar tests were variable, and this possibly may be attributed to the higher room temperature (25–30 C) prevailing during these experiments.
