9/5 Honeycrisp
(Northboro, MA)
nil 3.4 60 15.7 12.7 5.5
(4-7)
ready for 1st pick, good sugar
9/5 Honeycrisp
(Harvard, MA)
nil 3.2 55 14.7 11.3 6
(4-8)
very close to ready for 1st pick
9/5 Honeycrisp
(Stow, MA)
nil 3.2 45 16.8 10.9 5
(3.5-7)
most likely treated with ReTain?
9/9 Snappy Mac few 3.0 75 17 11.4 4.1
(4-5)
seeds dark; right on track for 1st pick as predicted; nice red color on these Snappy Mac
9/10 Lindamac some 3.0 80 15.7 11.6 4
(3-5)
Lindamac is a high red color strain, similar to a good color Redmax, but earlier coloring
9/9 Buckeye Gala nil 2.8 95 20 9.9 2.8
(1-4)
marginally ready for 1st pick based on background color change (which is hard to discern on these red Gala); sugar not there, but heavy crop load likely has adverse effect on sugar development
9/10 Honeycrisp few 3.1 60 15.7 11.4 6
(4-8)
note the higher starch index on these Honeycrisp from over-cropped Bud.9 trees, compared to B.118 below; probably never had much starch to begin with, and will not develop enough sugar for optimum varietal flavor
9/9 Honeycrisp few 3.4 65 14.7 11.2 4.6
(3-6.5)
sugars not fully developed, but needs a 1st pick, ripe fruit starting to drop; nice fruit gronw on Bud.118
9/10 Blondee® none 3.0 5 18 11.6 4.5
(3-7)
Blondee® is a fine yellow apple in this season, it's like a yellow Gala
9/10 RiverBelle®
(DS-22 cv.)
nil 3.6 70 16.8 13.9 5.5
(3-7)
RiverBelle® is a new, regional apple variety being planted in MN and WI; it is a very large, sweet apple designed for the regional market, but available to anyone who wants to plant; it most likely has a Honeycrisp parent; very large fruit, some russet/fruit finish issues

9/2 Honeycrisp few 3.1 55 18 12.3 5 (4-7) further along than expected, some background color change, ready for 1st pick this week!
