Nine sugarcane genotypes (CP59-73, CP63-588, CP80-314, SP71-1081, F160, L62-96, CP70-321, CP57-
614 and Clone III) were evaluated for their callus induction capacity, embryogenic callus production and
plant regeneration ability. Leaf cylinders were used as explants using Murashige and Skoog (MS) based
medium supplemented with 3 mg l-1 2,-4 dichlorophenoxyacetic acid. Plant regeneration was
accomplished on hormone free modified MS medium supplemented with casein hydrolyzate. The
genotypes tested showed high callus induction percentage (69 to 95%) and high embryogenic callus
percentage (60 to 100%). These genotypes also showed excellent regeneration capacities, with
regeneration percentages ranged between 88 and 100%. Significant differences were observed between
genotypes for callus induction capacity, embryogenic response and plant regeneration ability
indicating that these criteria are genotype dependent. Plant regeneration ability is highly correlated with
embryogenic callus production. The in vitro regenerated plants were successfully rooted and well acclimatised in growth cabinet conditions. |
