Description

1. The karyotype studies were made on thirty one races in Tulipa gesneriana.
2. All the races studied were diploid, having 24 somatic chromosomes.
3. The karyotypes of all the races used were analyzed. It was found that some of the karyotypes are similar to each other while the others are different from each other.
4. From the standpoint of the karyotype the thirty one races may be classified into seven types. A-1 type : Finland, White Cross, The Bride, Mildred, Maytime, Beverley, Saginaw and Nizza. A-2 type : Couleur de Cardinal, Superba, Aureola, Papago, Winnetou, Cum Laude Ceylon, Reliance, Pieter de Hoogh and Therese. A-3 type : Darlington. A-4 type : Prominence and Black Eagle. B type : Olaf, Gretha Benkemper, Golden Harvest, Henri Correvon, Neerlandia, Pride of Haarlem and Sweet Harmony. C type : Mount Erebus and Gay Hussar. D type : Chappaqua.
5. It was ascertained that as to the thirty one races the karyotypical classification supports the horticultural classification.
