Abstract

The present study deals with biochemical defense responses in Indian mustard varieties infected with Sclerotinia sclerotiorum causing Sclerotinia rot or white rot or stem rot. Eleven varieties viz., Bio-902, Kranti, Varuna, Manihari, Aravali, RRN-505, Navgold, NRCDR-2, Laxmi, RGN-48 and NRCDR-601 were selected. Total soluble sugar, total phenol and total protein in leaves of healthy and infected plants were estimated at 30 and 45 DAS,respectively.The total soluble sugar and protein were decreased in all the infected plants while the total phenol content was increased in infected plants as compared to healthy ones. The results indicated that varieties (Kranti and Laxmi) showing minimum reduction in total soluble sugar and total protein and higher increase in phenol content after infection were highly resistant and showed lowest disease incidence while it was vice-versa in highly susceptible varieties.
