covered an area of 6,000 hektares. All cultures are inspected while growing by
the specialists of the Association. The entire seed business of the Company, thus
the business with imported foreign seeds also, is under the strict control of the
Control Office of the Association of which Mr. J. N. Walldén has been super*
intendent from the beginning. All deliveries sent out by the Company, from the
largest to the smallest, are delivered under the seal of the Association, and with
a guarantee as to purity, germinating power etc- The number of sealed sacks
delivered last year was about 133,000, and all the seed delivered amounted to
about 8,200 tons. The annual export of elit and original seed of Svalöf sorts
amount to about 1,000 tons. Last year the Company paid the Association 117,500
crowns in compensation. The work of the General Seed Company, controlled by
the Seed Association, has greatly helped to bring the seed business to the relati*
vely high position which it now holds in Sweden.
The affairs of the Company and the Association are administered by different
councils. One member of the council of the Company and five belonging to
that of the Association (7 in all) are chosen by the Government in order to be
able to control the work of both and to excercise influence as to the use of the State
subsidies. The Association is also under the control of the Royal Board of Agri*
culture, which is subordinate to the Agricultural Department and is the highest
administrative authority for agriculture.
As well as at the Swedish Seed Association, plant breeding is also carried
on to a great extent and according to quite modern principles and methods at
Weibullsholm, a plant breeding institution near Landscrona, a town situated a
couple of Swedish miles from Svalöf. The work there began about fifty years ago.
The father of the present owner began about 1870 to cultivate and sell seed from
field roots as a by*trade. He soon began to try to improve these also, first by
mass selection of roots, according to their form, but later on with guidance of
their specific weight, gained by sinking them into a salt=solution of a certain con*
centration. About 1890, when the eldest son had begun to devote himself to
the improvement work, new principles were introduced, which were of decisive
importance for the future development of Weibullsholm. The pedigree method
began to be adopted 1898. The first scientist, Dr. Birger Kajanus, was engaged
1907. The improvement work is now carried on by four sections, each of them
with a scientific botanist as leader of the breeding work, assisted by an agronome
as leader of the practical trials. Kajanus has devoted his attention to winter
wheat, six»rowed barley, peas, vetches and forage plants. Dr. Nils Heribert*Nilsson,
Lecturer of Genetics, is responsible for rye, oats and potatoes, Dr. Carl Hallquist
has field roots and two*rowed barley as his speciality and Amanuensis Carl
Hammarlund has charge of the vegetables. The latter is also head of the Control
Office of the Institution. An extensive seed business is namely combined with
the improvement work. The leader of the whole firm is Harry Weibull, while
three of his brothers are responsible for a department each.
Since many years the firm has naturally dealt with its own improved sorts
and strains of all different kinds of field roots and their present sorts compete
with the best ones from Svalöf. As results of the improvement work it has also
