Mappe Green Mung Bean

Mappe Green seeds produce a mappe green mung bean. Plants have an upright habit. The mature height has not yet been confirmed for this exact seed lot. Seeds generally emerge in 5–10 Days at 75–90 °F. The first representative harvest is generally reached in 100-109 Days from direct sowing.

Minimum seeds per packet: 25 seeds.

About Mappe Green

Mappe Green is sold as a mung bean selection. The principal color is green, and the harvest form is Small green mung beans in slender pods; harvest dry for dhal or food-safe sprouting. Mild, earthy, and lightly sweet after thorough cooking. Best uses include cooked mung beans, dhal, dry storage, food-safe sprouting, and seed saving. Other seed records may list it as Bean.

History and seedkeeping context

Mappe Green is a named mung bean selection recorded by ECHO among Vigna radiata varieties. Mung bean has a long South and East Asian food history and is used as a cooked pulse, for dhal, and for carefully managed sprouting. The exact supplier strain behind this packet is not yet linked to a breeder or accession record, so no fixed plant height or elaborate origin story is assigned. The seed remains identifiable by its green mung-bean type, upright growth, and dry-seed use. Future Mappe Green grow-outs should keep the original supplier, packet wording, lot, year, location, isolation notes, representative plant count, and observed harvest traits together. That record can clarify the maintained line without making the name or family account stronger than the seed and documentation support.

Why this variety is distinct

Mappe Green needs a warm season and should be allowed to dry on the plant for dhal or storage. Sprouting for food requires clean seed and food-safe sanitation practices; garden seed instructions alone are not a food-safety protocol. Record plant stature and maturity in the next grow-out because those observations can help confirm whether the maintained lot matches published Mappe Green descriptions.

Harvest and kitchen or field use

Allow pods and seed to dry fully before shelling, and harvest before repeated rain or shattering damages the lot. The crop is described as Small green mung beans in slender pods; harvest dry for dhal or food-safe sprouting. Cooked mung beans, dhal, dry storage, food-safe sprouting, and seed saving. Mild, earthy, and lightly sweet after thorough cooking. Cook mature dry seed thoroughly before eating.

How to grow Mappe Green

Direct sow 1 in deep during the summer planting window. Keep the seed zone near 75–90 °F and evenly moist until emergence, normally 5–10 Days. Grow in full sun with sandy loam soil near pH 6.0–6.5. Space plants 4 in apart and rows 24 in apart. Keep the soil evenly moist through flowering and pod fill without leaving the root zone saturated. No trellis or staking is normally required, although low edging can keep heavily loaded plants off the soil. The mature height has not yet been confirmed for this exact seed lot.

Season care

• Wait for warm soil in the summer planting window before sowing Mappe Green; cold wet ground delays emergence and encourages rot.
• Water consistently through flowering and pod fill, then reduce irrigation as dry-seed crops approach final cure.
• No trellis or staking is normally required, although low edging can keep heavily loaded plants off the soil.
• Allow pods and seed to dry fully before shelling, and harvest before repeated rain or shattering damages the lot. The crop is described as Small green mung beans in slender pods; harvest dry for dhal or food-safe sprouting.
• Use 100-109 Days as the planning range, while allowing for shifts caused by weather, soil temperature, and plant stress.

Maturity and harvest timing

100-109 Days from direct sowing to the first dry-seed harvest under suitable conditions. Allow pods and seed to dry fully before shelling, and harvest before repeated rain or shattering damages the lot. The crop is described as Small green mung beans in slender pods; harvest dry for dhal or food-safe sprouting.

Saving seed

The crop is largely self-pollinating, but occasional insect-carried crossing can occur among compatible varieties. Save from several healthy, true-to-type Mappe Green plants rather than one exceptional individual. Mark seed plants before the eating harvest, remove clear off-types before they contribute pollen, and let seed reach full biological maturity. Shell only fully dry pods, discard moldy or insect-damaged seed, and dry the cleaned seed again before storage. Label the lot with crop, variety, source, year, location, plant count, isolation method, and selection traits. Keep the original packet and lot history with the saved seed so later grow-outs can be compared without relying only on memory or seed color.

Common problems

Watch Mappe Green for bean beetles, aphids, leafhoppers, mites, pod-feeding insects, bacterial or fungal leaf spots, rust, mosaic symptoms, and root rots. Rotate away from legumes, avoid working wet foliage, water at the soil line, and remove badly diseased plants. Cold wet soil commonly causes poor emergence; excess nitrogen can create leafy growth with fewer pods. Save seed only from healthy representative plants.
