The varieties used were "Basmati 370" "Basmati 385" and "Basmati 198". The medium used was Murashige and Skoog (MS-medium). Different plant portions like seeds, roots and shoots were used as explant and were cultured on M5-medium supplemented with different combinations of plant growth hormones. The hormones used were 2,4 Dichiorophexy acetic acid (2,4-D) and Kinetin- Basmati-370 was the best for callus induction. Best callus induction and vigorous growth was observed from seeds cultured on media containing 0.5 mg/I kinetin and 2.0 mg/I 2,4-D.The response of roots and shoot expaints to callogenesis was little as compared to seed explant. The mature seeds of Basmati rice are the best source of callus.]]>Chen, C.C. and M.H. Lin,1976171724Fox, J.E.,196316793803Larkin, P.J. and W.R. Scowcroft,198160197214Murai, M. and T.
