This is a list of commonly cultivated varieties of sweet corn, and the approximate number of days from germination of corn plant to harvest. Unless otherwise noted with the term open pollinated, all varieties are hybrids.

Genetically modified varieties only available to large-scale commercial growers, such as Bt corn and glyphosate resistant corn, are not listed.

Standard (su) The oldest type of sweet corn contains more sugar and less starch than field corn intended for livestock. Tends to be heartier in respect to planting depth, germination and growth than other types. Begins conversion of sugar to starch after peak maturity or harvest, and as such is best eaten immediately after harvest.

Yellow su

Early Sunglow, 62 days Sundance, 69 days Early Golden Bantam, 80 days (heirloom, open pollinated. Introduced in 1902, this became the first widely grown yellow sweet corn. The original strain is now often called 'Golden Bantam 8 Row' to indicate it has 8 rows of kernels on the ear. A number of "improved" strains exist with 12 or more rows of kernels on the ear) Iochief, 80 days (1951 AAS winner) True Gold, 80+ days (open pollinated selection from Golden Jubilee Hybrid) Golden Cross Bantam, 85 days (Introduced in 1933, this became the first widely grown hybrid sweet corn for both home gardens and commercial growers) Golden Jubilee, 90+ days

White su True Platinum, 80 days (open pollinated) Martian Jewels, 80+ days (open pollinated, unusual purple stalks and cobs) Luther Hill, 82 days (heirloom, open pollinated) Country Gentleman, 92 days (heirloom, shoepeg type, open pollinated) Silver Queen, 92 days Stowell's Evergreen, 98 days (heirloom, open pollinated. In northern climates or higher altitudes, this variety may not reach full maturity in the growing season. However, before the killing frost entire stalks may be harvested, including the partially mature ears, and hung in a barn or shed. Ears may then be picked for a month or more, hence the name evergreen.)

Bicolor su Double Standard, 73 days (open pollinated) Butter & Sugar, 75 days Honey & Cream, 84 days G90, 85 days

Multicolor su Multicolored varieties are usually at their sweetest when the mature color just starts to "blush" on the kernels. Hookers, 70 days (open pollinated, white turning blue at maturity) Triple Play, 70 days (open pollinated, white-yellow bicolor turning partially blue at maturity) Painted Hill, 75 days (open pollinated, mostly white turning various pastels at maturity) Black Mexican/Aztec, 76 days (heirloom, open pollinated, white turning blue-black at maturity) Double Red, 80+ days (open pollinated, white turning dark red at maturity)

Sugary Enhanced (se) Contains even more sugars in relation to starch than su types, and as such is able to retain sweetness for 2 to 4 days with proper refrigerated handling. Somewhat less hardy than su types, it is known as a "tender" kernel and as such does not lend itself to mechanical handling. Does not require isolation from su pollen, although it is preferred. Some seed catalogs don't distinguish the heterozygous se (one se parent) and homozygous se (two se parent) varieties, but if they do, the homozygous se varieties will be labeled either se+, (se se) or SE.

Yellow se

Buttergold, 63 days Spring Treat, 67 days Sugar Buns, 72 days Kandy King, 73 days Bodacious R/M, 75 days Incredible, 83 days Miracle, 84 days Kandy Korn EH, 89 days

White se Spring Snow, 60 days Sugar Pearl, 73 days Whiteout, 73 days Cloud Nine, 77 days Silver King, 82 days (se version of Silver Queen) Argent, 86 days

Bicolor se

Silver N Gold, 60 days Sugar Baby, 65 days Bon Jour, 70 days Trinity, 70 days Bi-Licious, 72 days Temptation, 72 days Luscious, 73 days Ambrosia, 75 days Who Gets Kissed?, 78+ days (open pollinated) Precious Gem, 80 days Peaches and Cream Mid EH, 83 days Delectable R/M, 84 days

Supersweet (sh2) Supersweet or shrunken-2 types have four to ten times the sugar content of normal sugar (su) types and with proper handling is able to be stored for up to 10 days. Less hardy than even se types, requiring higher germination temperatures, precise planting depth and isolation from all other corn pollen for optimum results. The name derives from the shrunken, shriveled appearance of the dried kernel which is low in starch.

Yellow sh2 Extra Early Super Sweet, 67 days Takeoff, 69 days Early Xtra Sweet, 70 days (1971 AAS winner) Summer Sweet Yellow, 74 days Krispy King, 78 days Challenger, 80 days Passion, 81 days Jubilee SuperSweet, 83 days Crisp ‘N Sweet, 85 days Damaun, 85+ days (open pollinated) Illini Xtra Sweet, 85 days WIM, 80 days White sh2 Summer Sweet White, 73 days Treasure, 83 days How Sweet It Is, 85 days (1986 AAS winner) Camelot, 86 days

Bicolor sh2 Summer Sweet Bicolor, 73 days Honey ‘N Pearl, 78 days (1988 AAS winner) Aloha, 82 days Dazzle, 82 days Hudson, 83 days Phenomenal, 85 days

Synergistic (sy) Synergistic varieties combine differing genetics on the same ear. The first varieties developed of this type have 25% sh2, 25% se and 50% su kernels on the cob but now different combinations are possible. There is an increasing number of brand names and trademarks that cover specific genetic combinations under this general type. However, a common trait of all sy types is that isolation from other su and se varieties pollinating at the same time is not required, though isolation may still be recommended for maximum sweetness.

Yellow sy Applause, 72 days Inferno, 73 days Gold Standard, 76 days Honey Select, 79 days (2001 AAS winner)

White sy Illusion, 72 days Mattapoisett, 80 days Avalon, 82 days (White version of Providence)

Bicolor sy Sweetness, 68 days Pay Dirt, 70 days Revelation, 70 days Synergy, 76 days Montauk, 80 days (Delectable type) Kristine, 80 days (Cinderella type) Serendipity/Providence, 82 days Cameo, 84 days (Delectable type)

Augmented Supersweet Varieties of the augmented supersweet type combine multiple gene types on top of sh2. These varieties have 100% of the kernels containing the sh2 gene, but also have se and su genes in some portion of the kernels.

The augmented supersweet varieties have tender kernels like the se varieties. Therefore, mechanical picking is not recommended.

As with other supersweets, these varieties must be isolated from su, se and sy types pollinating at the same time to prevent starchy kernels.
