摘要
Fifteen genetically diverse roses were evaluated for the ability to undergo somatic embryogenesis. Over the two media (MS and 135), two sugars (glucose and sucrose), and two explants (filaments and petiole) used, 20 to 30% of the 'Tournament of Roses' callus was embryogenic whereas only crystalline callus was produced in cultures of 'Baby Love', 'Ingrid Bergman', 'Perfume Delight', 'Prominent', 'Sunflare', and 90-202. Cultures of 'Tournament of Roses' consistently produced somatic embryos whereas 'Baby Love' produced no embryos. An F, progeny of 'Tournament of Roses'x 'Baby Love' was chosen to test whether the ability to undergo embryogenesis in Rosa hybrida L. is heritable. Data collected from tests on F, progeny between these genotypes suggest that the ability to undergo embryogenesis is indeed heritable in an additive fashion.
