Evaluation of Exotic Potato (Solanum tuberosum ssp. tuberosum) Germplasm in North-western Hills of India

Abstract

In North-western hills of India, potato is grown under temperate long-day condition of summer (April to September). Late blight is a serious problem in this region and under epiphytotic condition, yield loss can be as high as 90 percent. Resistance to late blight and high tuber yield are thus the major requirements of potato breeding in this region. Information on the nature and magnitude ofvariability oftuber yield, its components and resistance to late blight is a pre-requisite for an effective breeding program for hill region.
