%X Hypocotyls and shoot tips were used as explants in in vitro plant regeneration of broccoli (Brassica oleracea subsp.italica) cv. Green Marvel. The explants were excised from sterile germinated seedlings and placed on shoot induction medium containing basal salts of Murashige and Skoog (MS) and various concentrations of 6-benzylaminopurine (BAP) and -naphthaleneacetic acid (NAA). The highest percentage of hypocotyl explant producing shoot (96.67%) and the highest mean number of shoots produced per hypocotyl explant (6.03) were obtained on 3 mgL1 BAP. Meanwhile, the highest percentage of shoot tip explant producing shoot (100%) and highest number of shoot produced per shoot tip explant (3.76) were recorded on 5 mgL1 BAP. For rooting of shoots, NAA, indoleacetic acid (IAA) and indolebutyric acid (IBA) at 0, 0.2 and 1 mgL1 were applied. Highest percentage of shoots with roots (100%) and highest mean number of roots produced per shoot (6.5) occurred on medium with 0.2 mgL1 IBA, while the maximum root length (2.46 cm) was attained on MS medium without plant growth regulator (MSO). Plantlets were successfully acclimatized in potting medium containing peatmoss, perlite, and vermiculite (3:1:1).
