Sugarbeet (Beta vulgaris L.) produces 35% of the annual global raw sugar and thus provides scope to plant breeders and seed producers for developing superior cultivars. Due to its allogamous nature seed production true to the type is difficult and laborious. Tissue culture has been considered as a useful tool for the improvement of sugarbeet (1). The development of genetically manipulated superior sugarbeet plants and its tissue culture is of vital importance. Several studies are being carried out world-wide on the in vitro regeneration of sugarbeet. Regeneration of shoots from callusing plant parts has been reported by a number of workers (2, 3, 4, 5, 6, 7, 8, 9, 10, 11). Regeneration of shoots from hormone autonomous callus has also been reported (12, 13). In vitro organogenesis and whole plant regeneration of sugarbeet is difficult due to the variations inherent in different genotypes, which can influence the hormonal response of callus (14). Up till now there is no reliably rapid method for whole plant regeneration of sugarbeet from in vitro cultures.
