We investigated the structure of floral organs and possibility of seed-set to breed a variety in ginger, Zingiber officinale Rosc. Floral bud was formed from collected domestic Seosan var. and foregin Thailand var, the number of florets per bud were 8 and 10 in Seosan and Thailand var, respectively. Flowering time ranged from 18 to 25 August irregularly at 4~5 pm. The flower has the long styled with fiber hairs on top of stigma and connected-two anthers. Pollens were mixed of circular and ellips shape and its extine was two layer structure. Callus formation from anther explants was effective with compact and embryogenic on N6 medium supplemented 2 mg/l of NAA(NCM). Plant regeneration was on the MS medium with BA of 1~2 mg/l from 40 days old callus after transferred callus medium.
