About Japanese Hulless
Japanese Hulless is an annual popcorn with white color, 61–72 in mature height or spread, and an upright/erect habit. Harvest form or size: Approximately 4 in ears. Botanically it is Zea mays L. Maturity or first bloom: 80-89 Days; germination: 7-10 Days at 70–85 °F. Best for block planting, dependable pollination, dry or fresh harvest, and seed saving. ‘Japanese Hulless’ produces small, pearly-white kernels that pop into light, tender puffs with almost no hulls,just crisp, clean flavor and satisfying texture.
History and provenance
Cornell documents Japanese Hulless as a white popcorn with compact plants and miniature ears. The exact identity of the seed lot remains tied to its supplier and lot records, so no additional lineage is assigned beyond the cited record. Growers saving seed should keep the original packet, source, year, and selection notes with the lot. Each batch bursts evenly, yielding popcorn that’s delicate, aromatic, and easy to enjoy without the tough outer coating found in most modern types. Once cured, the kernels pop beautifully, storing well for months without losing quality. A timeless variety for popcorn purists who value simplicity and taste above all else. This variety fits within that long seedkeeping history, where kernel color, ear form, maturity, and field performance were preserved through careful selection over generations.

Starting Japanese Hulless from seed
How to grow Japanese Hulless Popcorn
Botanical identity: Zea mays L. Life cycle: Annual.
Sow 1 in and use a seed-zone temperature near 70–85 °F. Expected emergence: 7-10 Days. Direct sow after frost when the seed zone is warm; do not soak seed in cold or waterlogged soil
Plant during Late Spring. Space plants 10 in apart with 30 in between rows or planting bands.
Provide Full sun, moderate water, and loamy near pH 6.0–6.5. Support: No-Support.
Garden performance and care
Plant Japanese Hulless in a block rather than one long row so wind-carried pollen reaches the silks. Keep the bed evenly watered from tasseling through ear fill, and protect mature ears from birds and mammals if seed saving. Expected emergence is 7-10 Days; the listed maturity or bloom timing is 80-89 Days.
Harvest, bloom, and uses
Japanese Hulless is best for block planting, dependable pollination, dry or fresh harvest, and seed saving. Harvest form or size: Approximately 4 in ears. Color at the principal harvest or mature stage: White. ‘Japanese Hulless’ produces small, pearly-white kernels that pop into light, tender puffs with almost no hulls,just crisp, clean flavor and satisfying texture.
Saving seed
Seed saving for Japanese Hulless Select several healthy, true-to-type plants so the saved lot represents the variety rather than one unusually early or large individual. Corn is wind-pollinated and highly outcrossing. Grow a substantial population in a block rather than one long row, and isolate the seed crop from other corn by distance, flowering time, or controlled pollination. Mark representative plants before pollen shed and remove clear off-types before they contribute pollen. For seed, leave ears until husks are brown and kernels are hard. Harvest before prolonged wet weather or animal loss, remove husks, and dry ears with strong air circulation until kernels cannot be dented with a fingernail. Shell, screen, and winnow only after full dry-down. Label the crop, cultivar, lot, year, field, population size, isolation method, selected plants, and any unusual ears. Store fully dry seed cool, dark, and protected from moisture and rodents. Test germination before an important planting.
Common problems
Japanese Hulless can be affected by poor pollination, corn earworm, armyworms, stalk lodging, smut, leaf diseases, birds, and rodents. Plant in a block, maintain even moisture at tasseling and silking, use balanced fertility, rotate crops, and inspect ears before storage. Uneven kernel fill usually points to pollen or silk stress rather than a seed-count problem.
