The object of the present Investigation was
to obtain chemical tests which would enable a rapid
and accurate identification of tubers to be made.
The importance of such a method of identification is
obvious from a consideration of the following points.
Under the regulations of the Ministry of agriculture
and the Department of agriculture for Scotland
varieties of potatoes used for seed purposes nave to
reach a certain standard of purify and the growing
crops are inspected for this purpose. After the
crops nave been Harvested however,,confusion may arise
from the similarity in appearance of the tubers of
different varieties and a rapid and certain method of
discrimination would in such cases be very valuable.
Work of this nature has already been carried out by
McIntosh whose investigation although of a preliminary
nature, made clear the possibility of differentiating potato varieties by chemical reactions.
