Crocus sativus Saffron Corms Available at JK Seed Bank Kashmir

Saffron bulbs

For Crocus sativus (saffron), genotype, corm calibre (size), and corm type are important because they strongly influence flowering, stigma yield, daughter-corm production, and field establishment.

1. Genotype
Crocus sativus is a sterile triploid (2n = 3x = 24) and is normally propagated vegetatively through corms. Therefore, farmers do not generally produce new saffron genotypes through true seed.
Important saffron planting materials can differ in:

• Flowering intensity

• Number of flowers per corm

• Stigma weight

• Crocin, picrocrocin and safranal content

• Daughter-corm production

• Resistance/tolerance to diseases and environmental stress

In Kashmir, local Kashmirisaffron material is particularly important for maintaining adaptation to the region's climate and traditional production areas.

2. Corm calibre
Corm calibre means the size/weight of the saffron corm used for planting.

Corm calibre & General expectation
Small corms	Mainly vegetative growth; limited flowering
Medium corms	Moderate flowering potential
Large corms	Better flowering and higher potential stigma yield
Very large, healthy corms	Excellent planting material when disease-free

For commercial saffron production, large, healthy corms are generally preferred because flowering is closely associated with corm size and stored reserves.

3. Corm type
Corms should preferably be:
Mother corm / flowering-size corm: Mature corm capable of producing flowers and daughter corms.
Daughter corm: Newly developed corm produced during multiplication. Small daughter corms may require one or more seasons to reach flowering size.
Healthy corm: Firm, undamaged, disease-free and without signs of fungal infection or rotting.
Diseased or damaged corm: Should not be used for commercial planting because it can introduce pathogens into the field.

Key point for Kashmir
For high-yield saffron cultivation, the best planting material is generally true-to-type, locally adapted, large-calibre, mature and disease-free corms. Rather than simply buying the largest corms available, growers should consider corm weight, genetic uniformity, health, dormancy status and certified source together.

If you are developing a Kashmir saffron planting standard, I can also give you a detailed Crocus sativus corm grading system (e.g., <5 g, 5–8 g, 8–12 g, >12 g), expected flowers/corm and estimated saffron yield per hectare.
Available saffron planting material

• Botanical name: Crocus sativus L.

• Crop: Saffron / Kesar

• Genotype/type: Cashmerian saffron planting material; Crocus sativus is a sterile triploid crop propagated vegetatively through corms.

• Corm calibre : Small, medium and large corms can be graded according to diameter and weight. For commercial production in Kashmir, corms above 2 cm diameter and around 10 g or more are commonly recommended as quality planting material.

• Corm type : Mature flowering corms and daughter/cormlet material, depending on seasonal stock.

• Mother corm: The mature corm that produces new daughter corms and supports their initial development.

• Daughter corms: Vegetatively produced corms that develop from the mother corm and become the next generation of planting material.

Important: Crocus sativus does not normally produce viable seed for commercial propagation; multiplication is primarily through corms. Larger, healthy and disease-free corms generally have better flowering potential than undersized corms.
For orders, growers should contact JK Seed Bank to confirm the current corm calibre, genotype/planting material, quantity, price and seasonal stock before payment.
