Abstract
Abstract In 554 bulbs from 38 populations of Lycoris sanguinea, several chromosomal variations have been discovered. Most of the bulbs have a common karyotype consisting of 22 acrocentric (A) chromosomes. Though their frequencies are low, some rearranged chromosomes which are aberrant have been found. The aberrants are as follows: 1. Subtelocentrics (ST); 2. Telocentrics (T′); 3. Metacentrics (M′); 4. Very small acrocentrics (a); 5. Very small metacentrics (m); 6. Acentric fragments (Ac); and 7. Dicentrics (Di) chromosome. All can be easily suspected to be derived from As. Some aberrations of the satellite chromosomes have been observed also. In addition, a new karyotype composed of 2n=32=31A+ 1M′ chromosomes has been found.
