- discussion of potential future physiology-focused apple rootstock trials (e.g., water use, productivity) – would be very regional in objectives due to climatic characterizations
- Astrid Volder noted roots are very influenced by local climate and soils, so that needs to be taken that into account; potential for a new coordinated trial that would be excavated (e.g., by air spade and Bobcat) every year to examine season-by-season root development
- discussion of dwarfing mechanisms that may vary by species – root hydraulic conductivity, graft union transport, earlier terminal budset, GA metabolism, shift in CHO partitioning to reproductive growth
- Jason Londo noted that weather data should be reported and archived for each trial and site for potential later analysis – he will work on a template or protocol
State reports were presented.
The meeting concluded at 11:30 am on 3 November, with expressions of appreciation to hosts Elena Coneva, her team, and Des O’Rourke, followed by a group lunch and an afternoon of orchard tours.
Three new apple rootstocks were released from the USDA/Cornell breeding program. CG5257 was named G.257, CG6006 was named G.606, and CG4004 was named G.484. They are all semi-dwarf rootstocks. G.257 is especially well-suited to weak-growing cultivars like ‘Snapdragon’. G.606 is well-suited to multi-axis trees. G.484 is well-suited to growing conditions in Idaho.
Multiple rootstock evaluation trials for apple, peach, cherry, and pear continue to be coordinated across North America, generating data and observations on performance under a wide variety of climates and soil types to better inform growers interested in adopting next generation rootstocks to improve or solve local production issues.
- After 5 years the tart cherry and sweet cherry rootstock trials have revealed several rootstock genotypes (Cass, Clare, Lake) with an undesirable propensity for suckering with both sweet and tart cherries in certain soils, and one genotype (MxM14) with significantly lower cropping precocity with sweet cherry.
- First year laboratory freezing studies to begin characterizing cold hardiness examined 21 apple rootstock genotypes, primarily the Geneva rootstock series, but some industry standards like B.9 and M.9. Some genotypes elicit enhanced acclimation or reduced deacclimation, with clear differences in the timing of maximal cold hardiness as well as the loss of cold hardiness at the end of winter. In general, the most cold hardy rootstocks were G.210, G.890, G.935, G.2034, G.814, G.87, G.257, G.213, G.202, G.214, G.41 while the most sensitive were M.9, G.11, CG.4004, CG.6589, CG.8189, B.9, G.222.
- First year laboratory freezing studies to begin characterizing cold hardiness examined 4 scion genotypes. Comparing field deacclimation response shows that scion genotypes tend to have greater deacclimation resistance than rootstocks. This suggests a potential for desynchronization between rootstock and scion for deacclimation and growth resumption. Field observations of differences in senescence between rootstocks and scions also point to differences in dormancy induction in early winter that could result in winter physiology differences.
- Cold hardiness analysis of ‘Red Haven’ peach bud samples on six peach rootstocks (Atlas, Bright’s Hybrid-5, Guardian®, Krymsk®86, Lovell, ControllerTM5 and Krymsk®1) at seven time points the fall/winter season revealed that Prunus hybrid rootstocks acclimate later in fall compared to peach seedling rootstocks (i.e., Guardian® and Lovell). However, among the Prunus hybrids, Krymsk®86 exhibited maximum mid-winter hardiness and delayed deacclimation in late winter. These studies are on-going.
- The apple rootstocks G.969, B.9, and M9T337 continues to demonstrate low bitter pit incidence with ‘Honeycrisp’ compared to other rootstocks. G.41, G.814, G.890, and G.5257 all continue to have higher than normal bitter pit incidence.
Outputs & Activities:
NC-140 trials on research farms and on commercial farms are valuable outreach tools because researchers can identify novel advantages as well as potential problems of new rootstocks that should be addressed with additional research before widespread adoption. These trials also provide growers opportunities to observe tree responses to new rootstocks firsthand. Results from NC-140 trials are used to develop rootstock recommendations for specific fruit varieties and growing location variables (e.g., soils, climate), as well as tree training and pruning recommendations for North American tree fruit production regions. The NC-140 cooperators are the primary source of information on rootstocks and training systems for deciduous tree fruit growers and associated industries in North American. Workshops for tree fruit growers were held by most cooperators in 2022 following the lifting of COVID social distancing regulations, addressing aspects of rootstock-influenced production such as cold hardiness, pruning and training, and orchard planting or replanting.
In 2022, NC-140 cooperators disseminated results related to the project by publishing at least 39 refereed journal papers, 26 extension fact sheets and newsletters, 12 popular industry articles, and made at least 25 presentations to peer scientists at conference as well as more than 30 outreach presentations to stakeholders.
- Three new apple rootstocks were released from the USDA/Cornell breeding program. CG5257 was named G.257, CG6006 was named G.606, and CG4004 was named G.484. They are all semi-dwarf rootstocks. G.257 is especially well-suited to weak-growing cultivars like ‘Snapdragon’. G.606 is well-suited to multi-axis trees. G.484 is well-suited to growing conditions in Idaho.
- Approximately 2000 Pyrus seedlings have been created from various segregating populations for phenotyping as potential rootstocks. 380 seedlings from two populations were genotyped and improved genetic maps were constructed for genetic analysis of vigor-related traits. 600 seedlings were phenotyped for canopy architecture with remote sensing tools (LIDAR and RGB). 20 diverse breeding parents were screened for fire blight susceptibility
- NC140-associated research is elucidating the effects of rootstock on fruit tree water relations, leaf function, and how these relate to tree vigor, nutrient uptake, and nutrient distribution to developing fruit. Rootstock effects on canopy growth and function were shown to be inherent to the rootstock genotype, independent of whether or not it is grafted to a scion.
- The initial five-year results of the organic apple rootstock trial were accepted for publication “Performance of ‘Modi®’ apple trees on several Geneva rootstocks managed organically: Five-year results from the 2015 NC-140 Organic Apple Rootstock Trial” (in press, Journal of the American Pomological Society).
- The initial five-year results of the vigor-limiting peach rootstock trial were published “Establishment performance of the 2017 NC-140 vigor-limiting peach rootstock trial across ten sites in North America” (Acta Horticulturae).
- The initial ten-year results of the sweet cherry rootstocks x training systems trial were published “Ten-year conclusions from the NC-140 sweet cherry canopy architecture-rootstock trials in North America” ((Acta Horticulturae).
- Fruit yields, quality and labor efficiencies in high density sweet and tart cherry and peach production systems are stimulating grower experimentation with these new canopy training concepts. Such canopy architectures are better at facilitating increased use of mechanization to reduce labor inputs and increased protective orchard covering and climate modification technologies that result in more consistent fruit production and lower pesticide use.
- High-density pear training systems coupled with improved rootstocks is generating new interest among NY growers to plant pears.
- The on-going studies of rootstock and scion cold acclimation and connecting cold hardiness level with deacclimation resistance in apples, peaches, and cherries will enable predictive modeling of climate change impacts on the temperate zone tree fruit industry. The performance results of the various peach rootstocks tested under NC-140 have had a significant impact on Colorado orchard productivity and grower profitability. Krymsk®86, a hybrid rootstock tested in the 2009 Peach Rootstock trial, has become the dominant rootstock for new planting of new orchards selections due to the trials results regarding productivity, tree vigor, cold hardiness and overall fruit.
