Regeneration systems from immature embryos of Bulgarian pea genotypes

Regeneration systems from immature embryos of Bulgarian pea genotypes Ten genotypes from Pisum sativum and Pisum arvense were screened for their regeneration abilities. Most of them were created through experimental mutagenesis from Bulgarian varieties and have various valuable agronomic traits. Embryonic axes from immature embryos were plated on modified Murashige and Skoog medium, containing different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-d), α-naphthaleneacetic acid (NAA) and benzyladenine (BA). Two schemes for direct and indirect organogenesis were established. Callus and shoot formation were induced on media containing 0.2 mM 2,4-d or 5 mM BA, respectively. Embryonic axes formed buds directly when plated on medium with 10 mM BA and 1 mM NAA. Organogenesis and adventitious bud formation were maintained on medium supplemented with BA and NAA. Rhizogenesis was induced on Gamborgs' B5 medium. All screened genotypes were able to regenerate plants with a high efficiency (50–100%) although some differences in their organogenetic response were observed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Plant Cell, Tissue and Organ Culture Springer Journals

Abstract

Ten genotypes from Pisum sativum and Pisum arvense were screened for their regeneration abilities. Most of them were created through experimental mutagenesis from Bulgarian varieties and have various valuable agronomic traits. Embryonic axes from immature embryos were plated on modified Murashige and Skoog medium, containing different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-d), α-naphthaleneacetic acid (NAA) and benzyladenine (BA). Two schemes for direct and indirect organogenesis were established. Callus and shoot formation were induced on media containing 0.2 mM 2,4-d or 5 mM BA, respectively. Embryonic axes formed buds directly when plated on medium with 10 mM BA and 1 mM NAA. Organogenesis and adventitious bud formation were maintained on medium supplemented with BA and NAA. Rhizogenesis was induced on Gamborgs' B5 medium. All screened genotypes were able to regenerate plants with a high efficiency (50–100%) although some differences in their organogenetic response were observed.
