In vitro inducted tetraploid Petunia hybrida of a red color
Original language description
Petunia hybrida is one of the most important annuals. Niche of the assortment represent a group of tetraploid varieties that are interesting due to their giant flower. However, these are only old open pollinated varieties. Creation of homozygous tetraploid lines is a prerequisite for making F1 varieties. To do so, two homozygous lines used in commercial production of F1 varieties were used. 10 days old seedlings grown on MS medium with 8 g/l Agar and 20 g/l sucrose were treated with a solution of 30 μM oryzalin for 24 hours in in vitro conditions. The plants were washed and transplanted to the same medium. Later, they were grown in the greenhouse. Cytometrically, ploidy was detected. The yield of tetraploids was more than 50%. Octoploid plants were not found. Tetraploid red flowering plants with genotype GGGG and gggg were obtained. Flower size increased by at least 30% for polyploidy.
