A reproducible in vitro shoot regeneration protocol was developed for pigeonpea variety ICPL 87 through proliferation of axillary buds from cotyledonary nodes. The seedlings were cultured on MS + Kin (2 mgL-1) + BAP (5 mgL-1) medium and de-capitated on 7th day of culturing, which resulted in the induction of multiple shoots from cotyledonary node region after 15 days of culturing. Miniature shoots were elongated on MS + adenine suphate (30 mgL-1) medium; the elongated shoots were rooted ex vitro using a rooting powder ROOTEXTM.
