Abstract
Bulbing response of two accessions of shallot and two accessions of A. X wa kegi collected in Indonesia and two A. X wakegi accessions in Japan to dayl ength and temperature was investigated. All accessions formed bulbs under a 16-hr photoperiod. Both species also formed bulbs under a 12-hr daylength; A. X wakegi formed bulbs even in an 8-hr daylength. Temperature of 20 degr ees C more promoted bulbing in both species than at 25 and 30 degrees C.
