the MS medium containing 3 mg/L N6-benzylaminopurine (BA) and 0.5 mg/L 2,4-
dichlorophenoxyacetic acid (2,4-D) was found to be the most effective for multiple shoot formation
in HOR7231 cultivar that could produce 12 shoots per explant. The other cultivars HOR4409 and
HOR3844 produced a minimum number of adventitious shoots (1.33 and 1.67 respectively) on MS
medium supplemented with 1 mg/L BA and 0.3 mg/L 2,4-D. The elongated shoots were separated
and successfully rooted on MS medium containing 1 mg/L indole-3-acetic acid (IAA).
