Use of Electrophoresis and activity of Peroxidases in Selection of Potato (Solanum Tuberosum) Clones Resistant to Late Blight (Phytophthora Infestans)

Abstract

Use of electrophoresis of leaf peroxidase isozymes in selecting potato clones resistant to Phytophthora infestans was studied. The relationship between leaf peroxidase activity and foliar resistance to P. infestans as well as the effect of inoculation on pattern and activity of peroxidases were also investigated. The purpose of the study was to look into the possibility of using a rapid biochemical method of selecting potato clones resistant to the most serious potato disease, P. infestans.
