An efficient protocol for in vitro regeneration of peanut (Arachis hypogaea L.) cultivar L14




Arachis hypogaea, In Vitro Propagation, Rooting, Shoot Multiplication, Shoot Regeneration.


The present work aims to establish an efficient protocol for in vitro regeneration of peanut (Arachis hypogaea) cultivar L14. The study showed that de-embryonated cotyledon was a suitable explant for shoot multiplication on MS medium containing 4 mg/L BAP. The highest number of shoots per explant obtained after 4 weeks of culture was up to 6.8 shoots. Shoots in vitro were able to produce a large number of approximately 11 roots on MS medium supplemented with 0.5 mg/L NAA. These results will be very useful in establishing an in vitro regeneration protocol for peanut cultivar L14 during gene transfer in the next studies to improve their disease resistance.
