Conteúdo: | Over recent years in-vitro micropropagated Musaceae have been more and more widely used both for the international exchange of germoplasma and the production of healthy planting material. As a result of the increase in the latter use, the banana is probably the most intensely micropropagated crop. The main somaclonal variations that affect Musa are stable in the field after several crop cycles (Vuylsteke et al. 1988; Israeli et al. 1991). The percentage of variants varies considerably, including in apparently identical micropropagation conditions. The main characters concerned by the variations are those most frequently subject to natural mutation (Stover 1988; Vuylsteke et al. 1988). The two first above characteristics led us to approach the problem from the theoretical point of view: we looked for a mathematical model able to describe the variations in the percentage of variants over several sucessive cycles of in-vitro multiplication. The conclusions we drew from this study allowed us to define a number of pragmatic production strategies to limit the problem by combining risk management with early identification of variants. The outlook for future research is described.
