Somatic embryogenesis and shoot organogenesis in peanut cv. 'Georgia-12Y' and successful transfer to the soil.

ABSTRACT: An efficient regeneration system was established through somatic embryogenesis and shoot organogenesis using mature embryos explants of peanut cultivar 'Georgia-12Y'. The role of plant growth regulator combinations was investigated for embryogenic callus and somatic embryo induction. Results showed that Murashige and Skoog (MS) medium supplemented with 20 μM picloram (4-amino 3, 5, 6-trichloropicolinic acid), casein hydrolysate (0.2 g/L), sucrose (30 g/L) and sorbitol (10 g/L) supported callus induction in dark and higher number of somatic embryos in light. No somatic embryos were induced at 0.1 μM to 10.0 μM of 2,4-Dichloro phenoxy acetic acid (2,4-D) and picloram individually. The highest regeneration frequency of 90% was recorded on 40 μM 2,4-D + casein hydrolysate (0.2 g/L), sucrose (3
