Abstract
For the effective utilization of healthy and precious planting material, one-time multiplication of extremely small mini-tubers of potato under protected conditions is an alternative option to improve the size of progeny tubers for making them suitable for field multiplication. With this objective, the extremely small potato mini-tubers, viz. < 1, 1–2 and 2–3 g, produced during Kharif and autumn seasons were evaluated for their production behavior and health status under polyhouse (aphid proof) conditions of northwestern India (2700 m above mean sea level) during 2012 and 2013. The study revealed that mini-tubers produced during both the seasons had almost similar production potential and can be multiplied simultaneously without any special treatment. The number of tubers/m2 was more with mini-tubers grown in Kharif season than the autumn ones, but the yield was similar with the mini-tubers from both the seasons. However, plant vigor, number of tubers and yield were significantly affected by the grade of mini-tubers. The ELISA test of 5% plants raised from the mini-tubers from both the seasons revealed 100% healthy stocks in all the grades of mini-tubers.
