Mexican Red is a great variety with good size, attractive skin and flesh color, and sweet flavor. There is more Mexican Red in the background of varieties that I have released than any other variety. Seedlings tend to produce either mostly red or mostly white tubers.
Oca is normally propagated vegetatively, by replanting tubers, which are clones. Probably because oca has been grown this way for hundreds or thousands of years, it is difficult to get true, botanical seed, which is the key to breeding new varieties.
When you grow out true oca seed, you will get a brand new variety that you can maintain indefinitely by replanting the tubers. Plants that are propagated vegetatively are very appealing this way: if you get a plant that you like, you have a stable new variety that is all your own.
Unlike our mixes, which contain seeds harvested from many different varieties, these seeds are all collected from a single parent variety, although they were open pollinated. Varieties grown from this seed are more likely to be similar to the parent than varieties from one of our seed mixes, although they may also sometimes bear no clear resemblance due to oca’s octaploid genome.
