Rapid Biochemical Method for Screening the Fenugreek Germplasm Against Powdery Mildew Disease

Abstract

Fenugreek (Trigonella foenum-graecum L.) is an important multi-purpose cash crop ofindia grown during winter season. It is prone to many diseases and amongst them, powdery mildew caused by Erysiphe polygoni DC is the most devastating and serious which alone causes more than 50 per cent yield losses. Breeding resistant varieties to this disease is ofpriori consideration, for which screening of germplasm is a pre-requisite for the identification of resistant sources. Certain Oiochemical compounds like phenols and oxidative enzymes have been reported to impart resistance to many diseases in various crops but this information is lacking
