EXPERIMENTS WITH KHERSON AND SIXTY-DAY OATS. 6 
ment, the name u Kherson" was given to it. Seed of the Sixty- 
Day variety was received by the Office of Foreign Seed and Plant 
Introduction of the Bureau of Plant Industry 1 on. March 6, 1901, 
from Dr. S. de Mrozinski, of Proskurov, in the Podolia Government 
of Russia. This province is adjacent to and just west of the Kherson 
Government, and has essentially the same climatic and soil conditions. 
Both these varieties have been widely distributed in the United States, 
though probably the Sixty-Day is most widely grown. The origin 
of the Kherson oat is not definitely known. The Sixty-Day is said 
to have been originated by Dr. Mrozinski, but no information is at 
hand regarding the source of the material from which he made his 
selection. It is very probable, however, that the Kherson is from the

same original stock, as the two varieties are practically identical in 
every way and were obtained from adjoining provinces. A field of 
Sixty-Day oats in shock near Dickinson, N. Dak., is shown in figure 1. 
A brief account of the section of Russia from which these vari- 
eties were obtained will be of value for comparison with soil and 
climatic conditions in the United States. As is pointed out in the 
following quotation from Carleton (9, pp. 8, 9), the Russian grain- 
producing region, of which the Kherson and Podolia Governments 
i "S. P. I. No. 5938, Avcna saliva. From Proskurow, Russia. Received through Dr. S. de Mrozinski 
March 6, 1901. Sixty-Day, originated by Dr. Mrozinski. " (47, p. 44.) 
An earlier importation from Dr. Mrozinski was unnamed, but undoubtedly is identical with the Sixty- 
Day. It was grown at a few agricultural experiment stations under the name of ' Seventy-five Day, " but 
was not widely distributed and soon became merged with the introduction just mentioned. The exact 
date when this importation was made is not stated in the record, but it was about June 1, 1900. The record 
i<s as follows: 
"51G3. Avena saliva. From Proskurow, Russia. Presented by Dr. S. de Mrozinski. An 
early variety which ripens within 75 days from the seed." (46, p. 57.)
