SUMMARY     Initiation of flowering of Edward, Haden and another 129 cultivars of the National Center of Agricultural Research (INIA-CENIAP) was established and related with rainfall and temperature regimes that preceded them during the annual production cycles of the period between 1998 and 2001. Results indicated that flowering initiation is associated with the occurrence during the 30 days that preceded, of an increment of the frequency of night temperatures equal to or less than 20 °C. They also suggest the existence of different requirements among cultivars, independently of their place of origin. During its occurrence, the presence of a dry period or of scarce rainfall favored the process.
