BY520-9, A Peach Rootstock for the Southeastern United States that Increases Scion Longevity

Abstract

BY520-9 is being provisionally released as bulk seed for industry testing as a rootstock for peach and nectarine [Prunus persica (L.) Batsch] where root-knot nematode (Meloidogyne spp.), peach tree short life (PTSL) associated with ring nematode (Criconemella xenoplax (Raski) Luc & Raski], or both are a problem. BY520-9 consists of open-pollinated seed of 69 selections from B594520-9, which traces back to S-37 and Nemaguard.
