|resistance to peach tree short life syndrome
|Peach tree short life (PTSL) is a devastating disease syndrome of peach [Prunus persica (L.) Batsch] caused by multiple factors; the molecular biology of its tolerance/susceptibility is unknown. The difficulty of studying PTSL is that tree survival or death is not obvious until 3 to 5 years after planting when the symptoms of PTSL first appear. Tolerance to PTSL was unknown in Prunus until the rootstock Guardian ‘BY520-9’ was introduced into commercial orchards in 1994.
