| Abstract: | The hexaploid interspecific hybrid HH-1 (6x) was obtained from the cross of cultivated strawberry cv. Honeoye (8x) with the natural wild species Heilongjiang 1 (5x) . 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 cultivars Honeoye and Hokowase. The origins of the seedlings with various ploidy were postulated. |
