Abstract
Leucanthemum rotundifolium and L. praecox are diploids (2n = 18) being thoroughly different in their morphological characteristics and their distribution area. Though having the same chromosome number both species differ in their chromosome size and morphology as well as in chiasma frequency.
In L. rotundifolium there are 3 types of chromosomes (length 5,5 — 7,6 μ) in the haploid set: 4 metacentrics, 3 submetacentrics and 2 sub- metacentrics with satellites. The number of chiasmata is 2 — 3 per bivalent.
L. praecox however has 4 types of chromosomes (length 4,6 — 6,8 μ) in the haploid set: 2 metacentrics, 4 submetacentrics, 1 metacentric with satellite and 2 submetacentrics with satellites. There are usually 1 — 2 chiasmata per bivalent.
