Because many Gunter Blue tubers get really big, large packets may only contain three tubers instead of the usual five. They will still give the same number of plants (12-15) when cut into seed pieces.
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. As the tubers reach maturity, they develop netting, becoming a sort of blue russet. 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. I have found that it performs pretty well when dry farmed and have received a lot of feedback that it has performed well under harsh conditions elsewhere. 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. Although it is a poor pollen producer, Gunter Blue is fertile and self compatible. This variety is somewhat vulnerable to scab under dry conditions (as is often the case) but stays pretty clean with even soil moisture.
Fertility: MF2, FF8
True Seed (TPS)
TPS of Gunter Blue is open pollinated and largely self-pollnated. It was grown in a block with other blue fleshed varieties. It yields about half progeny with dark blue skin and blue flesh. The other half are a mix of pinks and light blues with white flesh and red with light red flesh. They are mostly late with short stolons, moderate to high tuber counts, and moderate to high yields. It is easy to select plants that are very similar to the parent variety from these seeds. As a bonus, Gunter Blue seedlings frequently have large, beautiful flowers. Somewhat slow germination, probably indicating that this seed has some dormancy.
