[Floral homeotic variants of in vitro seedlings in Sinningia speciosa Hiern].
Six types of floral homeotic variants of in vitro seedlings were observed in doubleflower sinningia. Type I, red and green mosaic petals exist in the outermost whorl of petal-whorls, 2.38%. Type II, the outermost whorl of petal-whorls exhibit green petals with thin yellow edge, 25.0%. Type III, green petals exist in the innermost side of normal red petal whorls, 1.78%. Type IV, multiple whorls of green petals exist in the inner side of normal sepals, no stamen and carpel, 1.67%. Type V, it exhibits duplicated whorls of sepals in the outermost, 7.14%. Type VI, it exists multiple whorls of green sepals, no petal, stamen and carpel, 0.12%. The total percentage of all types of floral homeotic variants is up to 38.1%. The distribution of nodal site of homeotic flowers were analyzed, and the results showed that the homeotic flower occurred mainly at the fourth and fifth nodes.
