Abstract (AB)A worldwide survey on sugar cane crossing programmes was initiated in March 1997 in order to provide breeders with comparative information on germplasm utilization, crossing techniques and seed processing activities. Data were collected from twenty countries through questionnaires and was subsequently validated through personal communications. Additional information and comments on the usefulness and efficacy of various practices were supported by literature search. Most breeding stations are located within latitudes 30°N and 30°S. Crossing extends from end September to mid-January and from April to July in the Northern and Southern hemispheres respectively. Most breeding stations use natural and artificial flowering for hybridisation, possess a reasonable collection of parents and conduct pollen fertility tests. A varying number of crosses are performed, mostly with excised marcotted stalks maintained in crossing solution. Controlled bi-parental crosses are becoming increasingly popular, but polycrosses, as an economic and efficient means to produce seeds, are also made at a number of stations. Most countries favour the proven parent, and use foreign parents to varying extent. Although the majority of stations maintain a collection of basic species, their use in the respective breeding programmes is limited to a number of stations. De-fuzzing is restricted to a few cases and most programmes maintain a seed bank.
