Abstract

Abstract: The hexaploid interspecific hybrid HH一1 (6x)was obtained from the cross of cultivated
strawberry CV．Honeoye(8 x)with the natural wild species Heilongjiang 1(5 x)．The botanical and fruiting
traits．meiosis and pollens of the hexaploid interspecific hybrid were observed．The hexaploid，heptaploid，
octoploid seedlings were obtained from the backcross of the hexaploid interspecific hybrid with cuhivars Ho—
neoye and Hokowase．The origins of the seedlings with various ploidy were postulated．

Key words: Fragaria, Strawberry, Interspecific hybridization, Ploidy, Hexaploid
