CHROMOSOME STUDIES OF SEVERAL ALLIUM-PLANTS

抄録

1. The karyotypes of the Allium-plants used in this study are as follows:
Allium Bouddhae Deb. form. giganteum (Makino) Araki K(2n)=16=14V+2J^T
A. Togashii Hara K(2n)=16=10V+4J₁+2J₂^t
A. Schoenoprasum L. var. foliosum Regel K(2n)=16=14V+2J^t
A. monanthum Maxim. K(2n)=32=22V+5J₁+2J₂+3J₂^t
A. Porrum L. K(2n)=32=24V₁+V₂+3V₂^cs+J+3J^cs
A. pseudo-japonicum Makino K(2n)=32=30V+2J^t
2. The chromosomes of the two varieties of A. Schoenoprasum (Kurita 1952, in this paper) seem to be fairly smaller than those of the other diploid form belonging to the race with the basic chromosome number 8. Thus, it seems possible to classify the race into two groups from the chromosome size.
3. There is no difference between the karyotype of A. pseudo-japonicum and that of A. Thunbergii.
