Late blight disease caused by Phytophthora infestans is the most destructive of all potato diseases and is recorded as responsible for the famous global famine in the middle of the 19th century in Ireland. It affects leaves, stems and tubers in the field and can absolutely destroy the crop producing up to 100% crop loss. Jos Plateau is noted for favourable cultivation of potato which is an economic crop grown in over 250,000 hectares of land area annually. However, this prospect is hindered by the ravaging late blight which has led to colossal losses in the past three years. Reports from current production suggests great loss has already been recorded this year; so far about 30% of the total harvest is lost due to the severity of the disease. Though farmers attempt to control late blight by spraying fungicides, the use of resistant varieties in combination with other control measures such as proper cultural management and growing potato outside the blight danger period is still the best approach and feasible to small scale farmers. A research was carried out in Kuru (a location in Jos-Plateau well noted for late blight attacks). Sixteen (16) advance varieties and clones from CIP were used to screen for their resistance
