Amey Azul came to exist from open pollinated true potato seed of Amey Russet in 2010 that for the purpose of this trial I called Amey X F1. I grew a large amount of TPS seedlings for 8 weeks indoors and transplanted them outdoors. Amey X results were 4 distinct segregates.
Amey X seedlings grown in 2010
Amey X F1 seedlings ready for transplant in early May outdoors.
At the time of transplant I noticed one russet and one blue potato. I was very intriged by the blue segregate and noticed in my growing notes that Amey Russet was next to Mule Skinner Blues at the time they both were flowering. Most likely this was the male donor for the OP TPS.
Segregation of Amey X F1 2010 shows 2 smooth skin potatoes and 2 russets. The smooth skin were pink and white flesh, yellow skin with pale yellow flesh and the russets were yellow flesh and white flesh. In this case it seems the russet gene is not fully express thus the skin is flaky strengthening the hypothesis that the donor was not a russet potato.
My interest is to be able to identify good potatoes as TPS seedling grow outs in terms of potential yield and flavor. In this case only the 2 russets has potatoes of significant size. Therefore from all these only the russets were selected to grow again. The first year grown as clone was only Amey X1 and Amey X2.
Amey X2 was impressive with good yield and was named Amey Azul. The flavor is not too impressive but makes a good salad potato.
Amey Azul failed to give TPS on the first year grown as clone but it showed lots of flowers and very sturdy sprawler plant. The following year as clone then produced abundance of berries that gave over 1000 true potato seeds. Self reliance and sustainability can be achieved by growing seedlings of Amey Azul TPS.
