A highly efficient regeneration system via somatic embryogenesis from immature embryos of Egyptian wheat cultivars (Triticum aestivum L.) using different growth regulators [electronic resource].

Two wheat cultivars (Giza 163 and Giza 164) were used to study the effect of three different growth regulators i.e. Thidiazuron (TDZ), Zeatin riboside (ZR) and Dicamba on regeneration efficiency. In comparing results of regeneration efficiency for the three growth regulators across the two cultivars, it is concluded that the highest regeneration efficiency was observed by using the highest TDZ concentration (0.2 mg/l) as compared with other used concentrations of the two other growth regulators. On the other hand, it was clear that ZR had higher influence on regeneration efficiency than Dicamba. Moreover, Giza 164 was better than Giza 163 in regeneration efficiency across all growth regulators and all concentrations. This highly efficient regeneration system is considered a new addition that will open the door for improving wheat crop by in vitro techniques.
