The original explant of each genotype was derived from a glasshouse grown, 20-30 day old seedling. The stalk of the seedling was surface sterilized in 20% 'Javex' for 20-30 min and rinsed three times with sterile distilled water. The sheaths of stalk were removed under the microscope in the culture hood to expose the shoot apical meristem. Each explant consisted of a shoot apical meristem with 5-6 nodes at the time of culture. The explant was placed in a small jar containing MS medium and other plant growth hormones (optimal) as reported in Table 1. Other incubator and growth conditions were same as in our earlier report (Bommineni et al., MNL 63: 87-88).
