Seedlings from Mark Albert fruits
In fall of 2015 Mark Albert brought loads of fruits from his selections to the talk he was giving for the Golden Gate Chapter of California Rare Fruit Growers . I planted the seeds from his best tasting fruit, and I grew 12 seedling trees in Vacaville. Some of them already fruited in 2018, and most are fruiting this year, 2019. Some are more precocious and productive than others. Seedlings 1, 2, and 12 didn't produce any fruit this year. Some are earlier ripening than others. Seedlings 3, 4, 5, 6, 7, and 10 are early ripening. Seedlings 8, 9, and 11 are late ripening.
I asked few friends to help evaluating the flavor to find the ones that deserve to be kept and may become good selections. In total, four people tasted them, and all of us found that 10, 7, and 6 (in this order) are the best selections from the early ripening seedlings.
The first picture here is from Chuck Chan with the fruits I sent him to evaluate
I compared how 7 and 10 taste versus one of my favorite named cultivars, Apollo. They seem to be on a par with Apollo. I could not place them higher or lower. These all seem to be very good fruits with unique profiles. I now call these seedlings Marta 7 (this became Cosmos after the registration with CRFG) and Marta 10 (Became Oktoberfest) and have the wood available at reallygoodplants.com
Evaluation of named feijoa cultivars
The fruits in the below picture were obtained from a friend growing them in Isleton. Left to right here: Albert Pride, Nazemetz, Unique, Moore, Genesis, and A9 (a seedling tree).
My favorites from this tasting were Moore and A9. Albert Pride was nice, but probably under-ripe. Unique does not have enough acid for me. Genesis was probably not ripe yet. Nazemetz is very mild and gritty with the most thick rind.
Below are fruits from my young trees in Vacaville
Triumph is a very good sweet fruit. I collected them much later than optimal, they all were soft, but still no browning inside.
8 Ball is very nice sweet, smooth fruit, mostly small sized fruits. Good sweet-acid balance.
Albert Pride was very good in this sample. Good balanced fruit, more acidic than 8 Ball. However, it browns fast after softening, limiting it storage
Another feijoa cultivar that I had for a long time is Coolidgei. It might be a seedling of Coolidge, or just a misspelled (on the tag) Coolidge. I'm going to continue calling it Coolidgei, as I bought it under this name 2001.
The tree is partially self-fertile, produces good tasting fruits. However, they are very variable is size and texture. They are also very gritty. Some fruits are very large, like the one below is 173 g.
