About Midori Giant Edamame Soybean

Midori Giant Edamame Soybean has a bush habit. Its principal color is green, and its pod or seed form is Green pods containing plump soybeans; the pods are not eaten. Flavor: Sweet, green, and nutty when cooked at the plump green-shell stage. Best for cooked green-shell soybeans, freezing, succession sowing, and seed saving. Maturity: 70-79 Days. Plant height: 19–24 in. Support: No-Support.

Botanically, Midori Giant Edamame Soybean belongs toGlycine max (L.) Merr.Common terms such as bean, pea, butterbean, cowpea, snap, shell, snow, dry, and edible-pod describe crop relationships or harvest uses; they are not interchangeable cultivar names.

History and provenance

University of California records identify Midori Giant as a determinate edamame soybean with 2 to 3 beans per pod and harvest near 75 days.

Edamame is soybean harvested at the green-shell stage. It is not a separate species, and the beans should be cooked before eating. Seed reserved for planting must be allowed to mature and dry rather than being taken from the green edamame harvest.

Where the surviving record is incomplete, the origin is described as uncertain rather than filled with repeated catalog folklore. A variety name, community association, or regional food use is not used to assign a tribal, ethnic, or national identity to a person connected with the present seed lot.

Pod, seed, flavor, and kitchen use

Midori Giant Edamame Soybean is selected for cooked green-shell soybeans, freezing, succession sowing, and seed saving. Sweet, green, and nutty when cooked at the plump green-shell stage. The relevant pod or seed form is Green pods containing plump soybeans; the pods are not eaten. Harvest stage determines texture and use: snap and edible-pod crops are picked young; shell beans and peas are harvested with full-size soft seed; dry beans and peas remain until the seed is mature and dry. Cook soybeans before eating, and do not eat the hairy pods. Culinary quality varies with harvest stage, weather, irrigation, and storage, so the description states a cultivar tendency rather than a guaranteed flavor result.

Sowing and establishment

Direct sow Midori Giant seed 1 in deep when the soil and season match this crop. Maintain a seed-zone temperature of 70–85 °F; expect emergence in 7–10 Days. Space plants 4 in apart with 24 in between rows. No structural support is normally required; use a short support only if lodging develops. Grow in full sun in loamy, well-drained soil near pH 6.0–6.5. Keep moisture moderate and especially steady during flowering and pod fill, but avoid waterlogged soil. Direct sowing is preferred because large legume seed and young roots can be damaged by rough handling. Apply nitrogen only according to a soil test; excessive nitrogen can produce lush vines at the expense of flowers and pods. Do not cultivate or harvest among wet foliage because bacterial and fungal diseases can be spread mechanically. Cook soybeans before eating, and do not eat the hairy pods.

Season-long care

Grow Midori Giant Edamame Soybean in late spring. The crop has a bush habit. Plant height: 19–24 in. Support: No-Support. Seed germinates in 7–10 Days at 70–85 °F; sow 1 in deep, space plants 4 in apart, and leave 24 in between rows. Provide full sun, moderate water, and loamy soil at pH 6.0–6.5. Frost response: Tender. Primary-harvest timing: 70-79 Days. Mulch after seedlings establish to moderate soil moisture and reduce splash. Scout weekly for chewing insects, aphids, distorted growth, spots, wilt, and pod damage. Rotate away from legumes when disease pressure has built, remove seriously diseased plants, and preserve source and lot information when replanting.

Harvest, food use, and storage

Harvest green-shell beans when seed is fully sized but soft, or allow pods to dry completely for pantry and seed use. Plan on 70-79 Days from direct sowing to the primary harvest stage. Use Midori Giant Edamame Soybean for cooked green-shell soybeans, freezing, succession sowing, and seed saving. Sweet, green, and nutty when cooked at the plump green-shell stage. Cook soybeans before eating, and do not eat the hairy pods. Cool fresh peas and green pods promptly after harvest. For dry beans or peas, reduce irrigation as seed matures, harvest before shattering or prolonged wet weather, finish curing under cover, shell or thresh gently, and store only fully dry seed. For canning, use a current tested pressure-canning process appropriate to the food; do not substitute an untested method.

Saving seed

Seed Saving
====================
Picking plants
Midori Giant is recorded as Open-Pollinated (OP). Select healthy, true-to-type plants that represent the maintained population rather than saving from one unusually early or large plant.

Isolation/Pollination control
The crop is largely self-pollinating but occasional insect-carried pollen can occur. Separate varieties and preserve the isolation method with the lot record.

Full maturity
Allow seed pods to pass beyond eating maturity and become fully mature for the species. Harvest before brittle pods shatter, finish curing under cover with airflow, then thresh or shell gently.

Harvesting seeds
Harvest in dry weather when possible. Keep plants or pods from different varieties and selections separate from the moment they leave the row.

Cleaning
Shell or thresh gently, remove chaff, split seed, insect-damaged seed, moldy seed, and obvious off-types. Large legume seed is easily damaged by rough handling.

Drying
Spread cleaned seed in a thin layer with airflow until it is fully dry before sealing. Do not trap field moisture in a jar or plastic bag.

Storing/Labeling
Label crop, cultivar or market class, source, lot, year, grower, location, isolation method, selection notes, harvest stage, and cleaning date. Store cool, dry, dark, and protected from pests.

Viability test
Before an important planting or distribution, test a representative sample and record normal seedlings, abnormal seedlings, hard seed where relevant, and dead seed.

Extra tips
Keep the original packet or photograph it. Compare the next grow-out with this variety description, and document any stable difference before changing the published traits.

Common problems and field diagnosis

Poor emergence usually follows soil that is too cold, saturated, crusted, or compacted, or seed damaged during handling. Recheck the listed germination temperature and seed depth before reseeding. Flower or pod abortion can follow heat, drought, waterlogging, excess nitrogen, or poor pollinator conditions in crops that depend more heavily on insects. Stringy pods often reflect overmaturity or water stress. Yellowing can indicate root stress, nutrient imbalance, disease, or normal late-season dry-down. Avoid diagnosing by one symptom alone. Use local Cooperative Extension guidance and preserve photographs, dates, weather, irrigation, and plant-location notes.
