Abstract

Abstract:

Lycoris radiata (L′Her. ) Herb. containing wild and cultural types, is distributed

in China and Japan. The karyotype variation in three populations of the species from Anhui

is studied in this paper. (1) Wuhu wild population has a karyotype 2n=21+1B= 1m+12st

+8t+1B. The chromosomes range in length from 7.50 to 14.10 µm with the ratio of the

longest to the shortest 1.88. The karyotype belongs to Stebbins’(1971) 3A. (2) Huang-

shan wild population has two cytotypes: 2n=22 and 2n=22+1B. Type Ⅰ: The karyotype

formula is 2n=22=12st+10t. The chromosomes range in length from 6.85 to 9.95 µm.

with the ratio of the longest to the shortest 1.45. The karyotype belongs to 4A. Type Ⅱ:

The karyotype formula is 2n=22+1B=6st+14t+2T+1B (plate 1: 7，8). The chromo-

somes range in length from 6.50 to 11.02 µm. with the ratio of the longest to the shortest

1.70. The karyotype belongs to 4A. (3) Wuhu cultural type has a karyotype 2n=33=30st

+3t. The chromosomes range in length from 7.10 to 9.35 µm with the ratio of the longest

to the shortest 1.32. The karyotype belongs to 4A. This result agrees well with the previous

reports. The diploid types of Lycoris radiata (L´Her.) Herb. are found in Anhui for the first

time.
