The production of lilies as cut flower has considerably increased in the last few years. One of the problem of lilies growth in the fields is need time for flowering. An alternative to overcome flowering problem is by growing genotypes that responsive to application of GA3 and modification of photoperiod. Therefore, it is necessary to evaluate the effect of application of GA3 and photoperiod on growth and flowering of some genotypes. This research used split-split plot design. As main plot was genotypes (VI (Lgfrx CK), V2 (Lgfrx LT1), V3 (Lgfrx Esp), V4 (LcBdg x CB) and V5 (LcBdg x SG)); as submain plot was photoperiod (neutral day and long day); as sub-subplot was four GA3 concentrations (0, 50, 100 and 150 mg/l). The result of the experiment showed that interaction between photoperiod and application of GA3 occured on increased plant height, number of leafs, diameter of bulbs, diameter of flower, initiation of flower, and vase life. An effective concentration of GA3 was 50 mg/l - 100 mg/l and application of photoperiod significantly increased initiation of flowering and flower quality. Isozyme analysis showed that application of GA3 and photoperiod caused increase number of band.
