| Research Abstract |
Genetic analyses and crossing tests were performed using euryhaline red alga Caloglossa leprieurii isolated worldwide, and the following results were obtained : (1) Apomixis occurred several times in the C.leprieurii lineages ; (2) 13 out of 18 apomictic strains were heterogeneous, and the strains from Florida and Australia were allotriploid ; (3) The homogeneous apomicts frequently produced tetraspores that grew into gametophytes ; (4) Obligate apomixis was generated through the outcrossing between the genetically divergent sexual strains.
