Seed Production of Potato

Potato Seed Production
  • Seed rate: Medium sized seed tubers at the rate of 15-20 q/ha
  • Isolation: 5 meters between potato seed plot and other potato plot.
  • Seed tubers: Medium sized, varietal purity, disease free, healthy sprouts.
  • Shade dry tubers after taking out from cold storage unit
  • Treat the tubers with 1 ppm GA for 5 to 10 minutes and dry in shade and fill in small gunny bags (30-40 Kg) and keep the bags in vertical position for 10 to 12 days for sprout initiation in dark ventilated place (10 to 12 0 C fav. Temp)
  • Rouging: 3 inspections minimum
    • 1st: 25 days after planting: all viruses affected and plants differing in leaf characters removed.
    • 2nd: 50 to 60 days after planting: Tubers formed. Virus affected and plants differing in foliage and tuber characters removed.
    • 3rd Just before cutting the foliage: Virus affected and off types plants removed.
  • Cutting haulms (foliage) and drying the foliage by withholding water is very essential when tubers are completely developed.
