Llumchuy Waqachi is one of those iconic, extra deep eyed Andean potatoes. We can grow it in North America, but it only develops really big, lumpy tubers if you can keep it going into December. I have been making crosses with it for several years, trying to get varieties that tuberize well under long days, but they usually lose the lumpiness. Here are a few that are showing some promise.
Yungay x Llumchuy Waqachi. This is the best yet, with a clearly defined shape.
Loowit x (GB Pink x Llumchuy Waqachi). Good size and nice color. I would like better defined lumps though, like in the variety above. These two will be a high priority cross next year.
Kinigi x Llumchuy Waqachi. This is closer to the typical results in LW crosses. Lumpy, but not impressively so. Still, it has high yield, reasonable tuber size, and blight resistance, so I will also cross it with the above varieties.
