Key Points for Potato Seed Selection

Source and Certification: Always buy certified seed tubers from reliable sources, an agricultural research centre, or an authorized seed-certification agency or from private company.
Tuber Size and Weight: Choose medium-sized, oval shaped tubers (roughly 30 to 50 grams in weight, or about 35–45 mm in diameter). Avoid oversized tubers, as they increase seed costs per unit area without providing an equivalent yield benefit.
Sprouting Status: Select tubers that feature short, stout, multiple green or white sprouts rather than long, weak, or excessively branched sprouts. Dormant (unsprouted) seeds take much longer to establish, while overly sprouted seeds are depleted of energy.
Disease and Damage Freedom: Discard any tubers showing signs of rot, soft-rot, blackleg, scab, cracking, or insect/mechanical damage. Any tuber oozing liquid or showing surface discoloration must be rejected immediately to prevent contaminating healthy seeds.
Whole vs. Cut Tubers: Whenever possible, plant whole tubers to minimize the risk of disease transmission. If large tubers must be cut to save on seed volume, slice them longitudinally through the crown eyes using a knife dipped in a disinfectant solution (such as potassium permanganate or a fungicide) between cuts.
Variety Matching: Pick a cultivar suited to your local climate, soil conditions, and intended market (such as table consumption versus industrial chip processing) rather than choosing a variety strictly because it is new.

🟢 Good Seed Tuber (What to Look For)
1. Visual Feature
Sprouts (Chitting)
Short, thick, green or dark purple/white sprouts emerging evenly from multiple eyes.
2. Skin & Surface
Clean, firm, smooth skin free of cracks, dark lesions, or fungal growth.
3. Size & Shape
Uniform, egg-sized rounded or oval tubers.
🔴 Defective / Bad Seed Tuber (What to Avoid)
1. Visual Feature
Sprouts (Chitting)
Long, weak, stringy, or "hairy" branched sprouts indicating aged/exhausted seed.
2. Skin & Surface
Wrinkled, shrivelled skin, wet spots, soft/rotten patches, or oozing fluids.
3.Size & Shape
Over-sized irregular shapes or tiny, weak, deformed chips/tubers.
