Karyotypic Studies of Local Amaryllis

Abstract

Karyotypic studies of 3 varieties of local amaryllis, i.e. red-flowered (R), pink-flowered (P) and orange-flowered (O), revealed the same chromosome number of the varieties, being 2n=2x= 22. The karyotypic formulae of varieties were as follows; R : 2n= L₁₀^a+ L₂^sm+ M₂^a+ M₂^sm+ S₄^sm+ S₂ ^sm ,P : 2n= L₂^sm+ L₈^a+ M₄ ^a + S₆ ^sm + S₂ ^sm and O : 2n= L₄^sm + L₁₀ ^a+ M₂^m+S₆ ^m
