Post-release Performance of MP-29, an Interspecific Plum-peach Hybrid Rootstock for Peach

Following the release of MP-29 rootstock in 2011, data collection has continued in both research and grower-cooperator trials. To date the performance of MP-29 in terms of its resistance to peach tree short life, Armillaria root rot and root-knot nematodes has exceeded expectations. Additionally, its horticultural performance both in terms of yield and fruit size, issues that have been problematic with other interspecific hybrids, has been excellent. Data will be presented on MP-29 and the next generation of rootstocks for peach now approaching release.
