Super Waldin Avocado Seedling 7516  Dry weight  15.45% 

September 12, 2020:  This is the second Super Waldin that caught my eye, actually about 3 weeks ago. This tree is one that I clearly remember cutting back the shoots coming out of the roots year after year. . It is actually building its own trunk just out of pure force.  I will be posting pictures and details soon.
This particular fruit, looks very close to Waldin,  produces very uniform large seeds, Seems to be running a bit later maturity wise. 
A big plus, we really love the eating quality of the fruit. It can become one of our favorites this time of the year. Much better than the parent.  Also the fruit is very clean, no disease showing, bright,  shinny, smooth, and beautiful. I planted some of the seeds to observe and use as rootstock, over  30.
​September 13, 2020. I picked 8 fruit at random. The fruit sizes were. 20.6, 21.9, 18.6, 19.2, 20.9, 22.4, 22.7, 21.2  oz.  Average weight 20.9 oz. At this time of the years packer should love this uniform fruit.
The seeds: relative uniform size and weight average size 60 mm, ranging from 56-65mm.  Seed weight  3.7 -5.1 oz.  average 4.5 oz.  Very clean seed, all tight in the cavity none rooting indicating they could hang in the tree a bit longer.  
Today I packed 5 seeds and placed in the refrigerator to see how they will sprout in 30 days. Going to wait 60 days.  For micrografting you need small shoots.
September 17, 2020: today I opened 7 fruits to evaluate the seeds, they ranged from 4.0 oz. to 4.7 oz.  averaging 4.4  oz. and size from 57 mm to 63 mm averaging 58.4 mm. Very consistent seed.​
September 30, 2020:  Have tried more of these. Seed seem to be getting bigger, some 5.5 oz. and 65 mm, not necessarily a bad thing if this turns out to be a strong possibility of root stock material.
October 12, 2020:  The tree continues to hold the fruit without dropping. We continue to eat it at home, great quality, firm and tasty. The seed continue to fit tight in the cavity  with no visible roots growing. No disease on its surface in spite no additional sprays. Seems like this fruit can hold to mid late October but can be picked starting September 1. Great range. Definitely better tasting than the Waldin and definitely a later fruit. A big plus. 

October 28, 2020: This tree is just about finished, Saw some fruit on the ground. It can be called to have a maturity from September 1 to October 15. We have been eating a lot of this fruit since I'm saving the seed to see how they grow as compare with a true Waldin. This fruit has some very good characteristics: First is the flavor. Much better than the parent. The particular attribute that  I find fascinating is its ability to ripen and stay really good to eat for days. Most West Indies have a day or two when they ripe at their optical flavor. Then they go down the hill. outer skin get days they get soft and watery. Not this poppy, stays hard for days and keep nice and clean in the refrigerator. The one in the picture below you can see the skin turning dark and the fruit inside in firm and tasty.  The optimal ripening of this fruit is several days 4-6.   Another item in favor is that it comes a but later than the parent. The only possible drawback I see id the larger seed.   Is too early to see about a commercial application but I will be top working 4-5 trees with this 7516 to see.
