BREEDING FOR FLOWER COLOUR IN PETUNIA HYBRIDA HORT
The population of each capsule was raised in the M2 generation. Observations in the M2 pointed to a large variability in flower colour with EMS treatments. Although, gamma irradiation produced more colour alteration than in the M1 generation, their frequency was lower compared to the EMS treatments. However, the types of flower colour alterations produced by gamma radiation were different than those of EMS. The data obtained emphasized the utilisation of EMS and gamma radiation in the production of seeds with different flower colours in Petunia hybrida Hort.
