IN VITRO SHOOT INDUCTION OF THREE GRAPE (VITISVINIFERA L.) VARIETIES USING NODAL AND AXILLARY EXPLANTS

Abstract

Nodal and axillary explants bearing two buds each from three varieties of grape (Vitisvinifera L.), viz., Crimson
seedless, Bangalore Blue and Red Globe were micro propagated for induction of shoots on basal MS (Murashige
and Skoog, 1962) medium. Nodal-bud cuttings performed well in all the three varieties: Crimson Seedless T2
V1
(71.43), followed by Bangalore Blue T2
V2
(27.27) and Red Globe T2
V3
(20.00), whereas, axillary-bud cuttings of
just Crimson Seedless T1
V1
(15.29) survived, and, the other two varieties, Bangalore Blue T1
V2
(0.00) and Red
Globe T1
V3
(0.00), failed to survive. Hence, from the present findings, it is concluded that nodal-bud cuttings
from ‘Crimson Seedless’ grape variety are suitable for in vitro shoot induction on MS medium.
