Indirect regeneration and genetic fidelity analysis of acclimated plantlets through SCoT and ISSR markers in Morus alba L. cv. Chinese white

A reliable protocol was developed for in vitro micro propagation of Morus alba L.cv. Chinese white. Initially, friable callus was induced (242.8 and 128.5 mg) from in vivo leaf and nodal explants on Murashige and Skoog’s (MS) medium amended with 4.0 μM/L of 2,4-Dichlorophenoxyacetic acid (2,4-D) and...

Description
Summary:A reliable protocol was developed for in vitro micro propagation of Morus alba L.cv. Chinese white. Initially, friable callus was induced (242.8 and 128.5 mg) from in vivo leaf and nodal explants on Murashige and Skoog’s (MS) medium amended with 4.0 μM/L of 2,4-Dichlorophenoxyacetic acid (2,4-D) and 3.0 μM/L of Naphthalene acetic acid (NAA) respectively within 3 weeks. Shoot regeneration (12.2 and 8.6) was obtained from leaf and node derived callus on 6-benzylaminopurine (BAP) + Thidiazuron (TDZ) at 2.5 + 2.0 and 7.5 + 2.0 μM/L concentrations respectively, after 4 weeks of incubation. In vitro shoots were rooted (90 %) on half strength MS medium with 7.5 μM/L indole-3 butyric acid (IBA) and plantlets were hardened in plastic pots contained farmyard manure, sand and garden soil in 1:1:2 ratio. The genetic stability of plantlets were confirmed by start codon targeted (SCoT) and inter simple sequence repeats (ISSR) primers based molecular analysis.
