Sugarcane is cultivated in almost all Brazilian agricultural regions, Brazil being the world's largestproducer, which requires breeding programs to create more productive and efficient varietiesadapted to each region. In sugarcane breeding programs there is a need, under certaincircumstances, to multiply the selected material rapidly. In this scenario, micropropagationappears as an alternative to the conventional process of vegetative propagation through stalks.The objective of this review was to describe the scenario on micropropagation research insugarcane, such as meristem culture, sugarcane calli, somatic embryogenesis, in vitro germplasmconservation and cryopreservation. It has been observed in the literature that there is a widespectrum of use for the numerous and well established protocols for the in vitro manipulation ofsugarcane morphogenesis. The prospect of producing new features via induction of somaclonalvariation and in vitro experimentation for pest and disease tolerance has not yet been extensivelyexplored. While benefits of minimal growth are recognized in in vitro germplasm conservation ofelite sugarcane cultivars, and all positive potential of this technique and cryopreservation may still 323Colloquium Agrariae, vol. 13, n.

On the other hand, techniques in the mass production of superior and pathogenfreegenotypes have already been integrated in many sugarcane breeding programs.
