Oops, that’s true. Sorry about that Greg.

Hello Everybody,
I am trying to figure out who is involved in the apple trials too. I am also looking for a potential coordinator and participates of the a new apple rootstocks trial 2018. We can discuss these subjects during the meeting. Actually I received a request of interest from Susanne Blatt. I would like to know if other State are interested.
I am also asking Gennaro if he can provide a list of new rootstocks from his program to be included in the new trial. It will be nice if you can present informally to the apple group some of the new genotypes you are testing.   I knew you are testing new genotypes also in Washington and I would like to know if you have in mind 3-4 genotypes interesting that can be included in the 2018 trial.
During the meeting I also would like to have a discussion about the future trials design and management.
Following the report of 2015  I build up this table please fill it with your name and if the trial have two cultivars specify which you have under evaluation.
It will take only few minute to do, but it can provide a general picture of the existing situation and the name of the person involved as referent. If your State is not listed in the table please add a column.
Kind regards,
Stefano

Here the apple section of the 2015 report.

A paper was submitted to the Journal of the American Pomological Society with the title “Time Required for Classifying Rootstock Vigor in Multi-location Rootstock Trials”. This paper will likely appear in the January issue of the JAPS. Data from the 1994 and 2003 apple rootstock trials were used to determine the time required to classify rootstock vigor. Very vigorous rootstocks, such as PiAu 56-83 and very low vigor rootstocks, such as M.27, were statistically different than standard rootstocks (M.26 and M.9 size class) by the fourth year after planting. Six or seven years were required to separate M.26 and M.9 NAKBT337, but rootstocks in the same size class (M.9 NAKBT337, G.935 and G.16) were not significantly different after 10 years. In future NC-140 apple rootstock trials, we should be able to accurately classify rootstock vigor after six or seven years at most locations.

The 2010 NC-140 Apple Rootstock Trial includes 10 Budagovsky, 16 Geneva, 3 Pillnitz, and 3 Malling (controls) rootstocks.  Fourteen locations use Honeycrisp as the scion cultivar, and 7 locations use Aztec Fuji.  All trees were supported to approximately 3.5 m and grown as Tall Spindles.  At the end of 5 growing seasons and across all locations, the largest Honeycrisp trees are on B.70-20-20.  This rootstock results in a tree much too vigorous for high-density planting.  The smallest trees are on B.71-7-11.  This rootstock results in a Honeycrisp tree which is too weak for commercial use.  Yield efficiency did not vary greatly among rootstocks, except that the most vigorous (e.g., B.70-20-20) are very inefficient.  Fruit size has been good for all Honeycrisp trees in this trial, except for those from trees on PiAu 9-90.  In the Fuji trial, some trees were lost in the first season due to damage in the nursery, but since that time, trees have grown very well.  At the end of 5 growing seasons, largest Fuji trees were on B.70-20-20 and the smallest were on B.71-7-22.  As with Honeycrisp, both rootstocks would be consider unacceptable.  Generally, yield efficiency was negatively related to tree size.  Fruit size was relatively consistent, except fruit from trees on B.7-20-21 were much smaller than those from all others. Trees on PiAu 9-90 continue to have severe chlorosis in BC, a sickly appearance, and often small fruit size.

The 2014 Apple rootstock planting was established in 15 locations in the United States (AL, ID, IN, MA, ME, MI, MN, GA, NJ, NY, PA, UT, VA, WA, WI), two in Canada, and one in Mexico (http://bit.ly/1zv3wCc). The trial consists of the following rootstocks: B.10, G.11, G.202, G.214, G.30, G.41, G.5890, G.935, G.969, M.26 EMLA, M.9 T337, V.1, V.5, V.6, V.7. The trial is being coordinated by John Cline who has also agreed to analyze the data. This trial has two cultivars: Aztec Fuji (AL, ID, GA, NJ, ON, PA, UT) and Honeycrisp (ID, IN, MA, ME, Mexico, MI, MN, NJ, NY, Ontario, PA, VA, WA, WI), planted to a ‘tall spindle’ systems at a 5 x 12 feet, and 4 x12 feet spacing, respectively. Trees are planted using a randomized block design with single trees serving as experimental units. Each site selected a pollinizer variety since some sites are very limited in adapted varieties. Trees were established in the spring of 2014. The trees were propagated by Willow Drive Nursery, WA. Data protocols have been established for 2014 and 2015. In 2014, the following data were recorded: 1) initial trunk diameter measured at planting 30cm above graft union; 2) number of side branches >10 cm at planting; 3) trunk circumference in the fall of 2014; 4) height of the graft union above soil; 5) tree status at the end of the 2014 growing season.

For the 2015 Organic Apple Rootstock Trial, trees have been dug at Wafler Nursery. The trial will be planted at 14 locations and will evaluate 9 Geneva rootstocks and 1 Malling rootstock.  Modi is the cultivar and Liberty will be the pollenizer.  The design is five blocks in two-tree sets and will require 1/10 acre.   Organic certification is optional, but orchard management must be organic.  Land does not have to be organically certified prior to planting.

I need to know who is participating in the 2015 Organic Modi Apple Trial.  In 2015, I received data from IA, MA, MI, NJ, NM, NY-Ithaca, NY-Geneva, Vermont, and WI.  My initial list suggested that California, Chihuahua, Colorado, Idaho and Nova Scotia were also involved, but I have not seen any data.  For the latter, please confirm whether or not you are part of this project.  If I don't hear from you, I will assume that you are not.
