| A survey of sugar cane selection schemes throughout the world was initiated in March 1996. The objective of the survey was to compare and contrast the different selection strategies and philosophies found in different countries. The main focus was on the length of the selection cycle as the Mauritian selection cycle was thought to be excessively long. By studying the different approaches to selection it was possible to discern common trends and individual differences. Several breeding stations have shortened their programmes recently. In Brazil (Copersucar) the time has been decreased from 16 to 13 years and Thailand has already an extremely short programme (7-8 years) and still wants to shorten this further. In Queensland the programme has been cut clown to 8-9 years by de-emphasizing evaluation in ratoons. The Louisiana Agrieultural Experiment Station programme was shortened from 14 to 12 years. The longest schemes were those of Mauritius, Réunion Island and South Africa (15-18 years) and the shortest (8 years) are those of Thailand and CSR (Burdekin). The average duration was l 1.5 years. The size of the initial seedling population was also of concern but the size of the population in the first replicated trials was thought to be the best comparative measure. The largest programme is In Indonesia with 1.2 million seedlings annually whereas the smallest is in Thailand with 20 000. Four stations test ratooning ability fairly early in the programme, namely: Houma, Louisiana, Mauritius, Réunion Island, whereas the others only test for this in variety trials. The largest programmes in terms of largest replicated population were Argentina and South Africa. Ali the information collected on selection (stages, rates, criteria, plot sizes, etc.) and commercial cultivation (number of ratoons, number of environments, etc.) from eighteen breeding stations has been stored in spreadsheet format. | |
