University of Florida rootstock released for grower trial is an interspecific peach-plum hybrid named ‘MP-29′. ‘MP-29′ expresses resistance to Armillaria root rot and has as good resistance to peach tree short life (PTSL) as Guardian™ rootstock. Peach scions that have been budded to ‘MP-29′ have displayed similar trunk cross-sectional areas as ‘Sharpe’ rootstock with higher yields of larger fruit, which increases yield efficiency. ‘MP-29′ has red leaves similar to ‘Flordaguard'. It does not produce any fruit and is useful only as a rootstock.
