Abstract

'Gulfrose', a new low chill Japanese-type plum (Prunus salicina Lindl.) from the University of Florida breeding program, was selfed and pollinated with 'Gulfbeauty' and 'Gulfblaze' at Gainesville, Florida. Visible pollen shed in the field for all 3 varieties. Pollen germination on 10% sucrose was 12% for 'Gulfrose', 9% for 'Gulfbeauty' and 28% for 'Gulfblaze'. Bagged shoots of 'Gulfrose' set and matured fruit when crosspollinated by 'Gulfbeauty' and 'Gulfblaze', but set no fruit when self-pollinated.
