Gunter Blue is a Cultivariable original variety, selected in 2019. It is a medium to large tetraploid with blue skin and flesh and very high yields. The female parent was Gunter Gold, a selection made from the Pacific Northwest heirloom variety Johnny Gunter, and the intended male parent was a selection out of Careta Amarilla, a Colombian diploid potato with intense yellow flesh. I suspect that cross didn’t actually take and that this caught some stray pollen from another variety, since a blue doesn’t make sense out of that cross. Oh well, it was a happy accident!
Gunter Blue is a pretty starchy/floury potato, better baked or roasted than boiled. The flavor is strong, not quite rising to bitterness, but you will know that you are eating a potato. While strongly flavored, it lacks the aftertaste that is common in blue flesh potatoes. Tubers range mostly between four and six inches. The skin is moderately thick, but not so much that it becomes chewy. The flesh is marbled when raw, but becomes a uniform light blue when cooked. If you like blue potatoes with an assertive flavor, you should like Gunter Blue.
Gunter Blue is a day neutral tuberizer with a late maturity. It is harvestable after about 100 days, but will continue to grow until killed by frost. At full maturity, plants typically yield between three and six pounds. Stolons can range from about 2 to 15 inches, so this variety benefits from a little extra space. The tubers are generally oblong, but less regular than commercial types, so you will get some that are extra long or have odd bends or unusual shapes. Flowers are male sterile and will require a pollinator to set seed. This variety is somewhat vulnerable to scab under dry conditions (as is often the case) but stays pretty clean with even soil moisture.
True Seed (TPS)
TPS of Gunter Blue is open pollinated. It was grown in a block with other blue fleshed varieties. In 2020, it grew between beds of All Blue and Azul Toro, so the seed should produce a lot of really nice blues. I expect the majority of the progeny to produce large, late plants.
