Abstract
Sorghum (Sorghum bicolor) landrace varieties show very large variation for the duration of their vegetative phase, ranging from 50 to 300 days depending on the sowing date (Miller et al. 1968). This variation is linked with the duration of the rainy season in their place of origin (Curtis 1968). Late sorghum varieties are known to be highly photoperiod-sensitive and, for a given variety, the flowering date remains more or less constant independent of sowing dates, which in the tropical areas of the northern hemisphere occur anytime between May and July. Even though the importance of matching sorghum flowering date to the end of the rainy season has long been known, relatively little has been done to improve these photoperiod-sensitive varieties until the past decade. The lack of new, improved sorghum varieties able to respond to the increased soil fertility in cotton (Gossypium spp) systems of Burkina Faso and Mali has most recently raised the need for this type of research, and breeding programs are currently addressing this objective (Bazile et al. 2003).
