Origin and Breeding<br />
‘Suplumtwentyfive’ arose from a cross of an unpatented breeding selection and an<br />
unknown low-chill plum variety as the pollen parent. The seed parent is Sun World<br />
breeding selection 90P-001, which was selected from progeny of ‘Suplumeighteen’<br />
crossed with pollen of ‘Ambra’. The seed parent requires approximately 600 hours<br />
winter chilling to break winter dormancy while ‘Suplumtwentyfive’ requires only 200<br />
hours winter chilling and does not have the bitter skin when ripe that 90P-001 has.<br />
Selection criteria: early fruit ripening, low winter chilling requirement. Propagation:<br />
vegetatively propagated - usually budding. Breeding: parents first crossed in 1996<br />
with first flowering in Feb 1999, first propagated in 2000 by T. Bacon, Kern County,<br />
CA, USA. Selected by D.Cain and first evaluated by D. Cain and T. Bacon, Riverside<br />
County, CA, USA.<br />
