Callus Induction and Shoot Regeneration of Lycopersiconesculentum L.

Niroj Paudel, Lila Pati Paudel, P. D. Rai

Abstract: The benefit of callogenesis and subsequent shoot regeneration using different lengths (3 mm, 4 mm, 5 mm, 6 mm, and >6 mm) of flower buds of tomato were investigated in another culture. Calli were induced on MS media Supplemented with different combinations of growth regulators (2 ppm indole3acetic acid (IAA) plus 1 ppm N6 (2isopentenyl) adenine (2ip), 2 ppm IAA plus 3 ppm 6benzylaminopurine (BA), and 2ppm IAA plus 0.25 ppm zeatin riboside). The developed calli were transferred to the MS medium containing 2 ppm IAA plus 1 ppm2ip for organogenesis and developed shoot buds were transferred to the same medium containing 2 ppm IAA plus 0.25 ppm zeatin riboside for shoot regeneration. The flower bud length ranging from 3 mm to >6 mm produced calli. Flower buds of 4 mm produced the highest number of calli and shoots (63 % and 29 % respectively) followed by that of 5 mm (57 % and 14 % respectively). Number of calli produced in the MS medium containing 2 ppm IAA plus 1 ppm 2ip were highest (71 %) followed by2 ppm IAA plus 3 ppm BA (65 %). This finding would be an efficient technique for callogenesis and shoo, 942, 416 Tm in 2007) and cultivated area (4, 643, 957 Ha in2007) (Seguto regeneration in tomato anther culture
