Impact of BAP on in Vitro Regeneration of Potato (Solanum Tuberosum L.)

The potato (Solanum tuberosum L.) plant is grown in about 150 countries of the world and is considered an important food crop. However, this crop is susceptible to different biotic and abiotic factors, which can affect its crop yield. This vulnerability can be reduced or eliminated by growing potatoes under sterilized conditions. Cytokinins, such as 6-Benzylaminopurine, are proven to show a significant role in the in vitro regulation of plants. In the current study, explants of Kuroda variety were/potato cv. Kuroda were grown using diverse concentrations of 6-Benzylaminopurine (BAP), which displayed varied results. BAP concentration of 0.01 mg/l showed a 10 cm shoot length with 41 shoots having 66.66% regeneration efficiency. Meanwhile, the explant grown in 0.25 mg/l BAP concentration showed 16 cm shoot length with 65 shoots having 83.33% regeneration efficiency. On the other hand, the explants that were grown using 0.05 mg/l and 1 mg/l BAP concentration showed 7 cm and 10 cm shoot length with 35 and 52 shoots having 63.33% and 76.66% regeneration efficiency, respectively. Therefore, it was concluded that 0.25 mg/L of BAP showed the best results with the highest number of shoots and shoot length as well as maximum regeneration efficiency among all the tested concentrations.
