• It yields 35-40 tonnes/ha tubers. Tubers are medium, red, round with medium deep eyes and dull white flesh.
• It is moderately resistant to early blight, tolerant to PLRV and has slow rate of degeneration and possesses long tuber dormancy.
• It is also tolerant to temperature and water stress to some extent. It is suitable for dehydrated instant flakes and canning.

Kufri Badshah

• It matures in 100-110 days. It is suited for cultivation in parts of Gujarat, Haryana, Jammu and Kashmir, Madhya Pradesh, Punjab and Uttar Pradesh.

Kufri Chipsona 1

• It is suitable for making chips, French fries and flakes.
• This variety can be grown in North Indian plains in main autumn season, with an average yield potential of 300-350 q/ha. 30-35 t/ha.
• Its tubers have average dry- matter content of 20-23% and reducing sugars of 10-100mg/100 g of fresh weight depending upon the location and cultural practices.
• The tubers yield acceptable chip colour from 90 days maturity onwards.
• The 110 days grown crop keeps well at 10-12°C for 4-5 months with respect to chipping quality.
• The variety has excellent keeping quality.

Kufri Chipsona 2

• Kufri Chipsona 2 has round tubers with shallow eyes and creamy flesh.
• The variety is well adapted in North Indian plains. It can be grown in main autumn season and to some extent in spring season.
