| Abstract | Diploid Torenia (Torenia foumieri x Torenia baillonii) is sterile, and chromosome number is 17 (2n=2x=17). They were duplicated chromosome number with colchicine tablets. There are 34 chromosomes (2n=4x=34). Which are fertile in tetraploid population. Morphological segregations were studied in F2 population. Seeds were harvested at 30 days after selfing, then were sew in peat moss with 500 ppm GA3. Two hundred and fifteen plants were studied segregation at the Horticulture Department University, Bangkhen campus. The results were shown continuous segregations in plant heights, which were between 4-30 cm, 2.6-41 cm for plant canopies, 1-32 cm for leaf widths and 1-3.9 cm for leaf lengths respectirely. Flower colours were shown the continuous segregation in blue and yellow colours, the flower colour were depended on blue ? yellow colour ratio. Discrete segregations were found in leaf and stem colour, the ratio was 3:1 in red and green colour. Segregations were not found in leaf shape and clambering. This result suggested that some chromosomes were homologous. |
