SOME REMARKS ON THE WORK OF THE
SWEDISH GENETIC INSTITUTE IN ÅKARP

BY

H. NILSSO N=EHL E

LUND

THE SWEDISH INSTITUTE OF GENETICS, FOUNDED 1917-1918
in connection with a new professorship of genetics at the University of
Lund, is situated in Åkarp, near the railway station of the same name,

9 km. from Lund, between Lund and Malmö. The institute lies on ground be«
longing to the State farm Alnarp, only a few minutes way from the Alnarp
Agricultural College. In this way the institute forms a connecting link between
the university and the agricultural college, and the experiments and the cultures
of the institute are easely demonstrated for students in Lund as well as in Alnarp.

The purpose of the institute is research in theoretical and applied genetics
combined with leetures. Genetics has been made a special subject at the Uni*
versity of Lund, and courses leading to a doctor’s degree in this subject are
offered by the philosophical faculty under the supervision of the professor in genetics.

The research of the institute is at present limited to plants. The writer
continues his former work begun in Svalöf, especially with cereals, but also expe*
riments with several wild plants are going on. The assistant of the institute,
lic. phil. G. Turesson, has at the moment extensive work with such plants,
Atriplex and others, under way.

The writer’s work on purely theoretical genetics now embraces researches as
to the mode of inheritance of a number of different genetic characters, studies
on mutations, coupling and multipe allelomorphs.

Since 1913 the writer has had very extensive experiments with some charac*
teristic mutations in wheat, called speltoid mutations by him. These mutations
offer great interest in many respects, especially since their nature of complex*
mutations has been almost proven; they involve, in other words, genetic changes
of several Mendelian genes simultaneously. The question of multiple allelomorphs
is closely connected with these complex*mutations. Furthermore, these mutations
have offered great advantage in studying the question of decreased vitality of
mutated pollen, of heterogamy, which is probably a form of coupling with sex*
genes of the haploid generation, and of somatic segregation. The results of these
researches have partly been published (Botaniska Notiser, 1917; Hereditas I, 1920,

II, 1921). More than a thousand plots of plants belonging to this investigation
series have now been grown in the experimental fields of the institute.

In barley a number of different chlorophylbmutations have been found,
which have been crossed with each other in order to elucidate the question
whether or not the different mutated chlorophylbgenes show independent segre*
gation or coupling. This work forms amongst plants an analogue to the American
investigations in Drosop/u7a=mutations. About 250,000 seed*plants of such crossings
have hitherto been examined and counted.
