White-flowered transgenic plants resulted from RNAi suppression of the CHS gene and dwarf transgenic plants resulted from overexpression of the GA2ox gene were selected as breeding materials through characterization of various transgenic plants of Tricyrtis spp. Interspecific hybrids were produced via ovule culture when dwarf transgenic plants were used as parents. Some of these hybrids showed not only dwarf phenotypes due to the transgene but also novel flower characteristics compared with the parents, indicating the possibility of interspecific hybridization using transgenic plants in the improvement programs of ornamental plants. On the other hand, induction of somaclonal variants and chromosome doubling were also examined by using embryogenic callus cultures of transgenic plants. Detailed characterization of callus culture-derived plants are now in progress.

通过对Tricyrtis spp各种转基因植物的表征，选择CHS基因RNAi抑制产生的白花转基因植物和GA2ox基因过表达产生的矮化转基因植物作为育种材料。当矮化转基因植物用作亲本时，通过胚珠培养产生种间杂种。其中一些杂种不仅因转基因而表现出矮化表型，而且与亲本相比还表现出新颖的花特征，表明在观赏植物改良计划中使用转基因植物进行种间杂交的可能性。另一方面，还通过使用转基因植物的胚性愈伤组织培养物检查了体细胞克隆变体和染色体加倍的诱导。愈伤组织培养衍生植物的详细表征正在进行中。
