Abstract
Black point in wheat has commonly been thought to be caused by
Alternaria alternata. To obtain a method for screening
for resistance to this problem, the process by which
A. alternata infects wheat grain was observed in
resistant and susceptible varieties. No association was found between
infection with A. alternata and black point symptoms. A
technique was developed to produce symptoms in vitro
which showed the detection and location of the peroxidase enzymes involved.
Isoelectric focusing (IEF) determined considerable differences in peroxidase
isoenzyme activity from black point resistant and susceptible wheat varieties.
The potential exists for using IEF as a tool for rapid screening for black
point resistance.
