Abstract

Potato is known to be the richest source of carbohydrates and it is the staple food of many countries. The objective of the present study was to evaluate three potato lines viz. VR-96, VR-94725 and V-3 against Rhizoctonia solani. Results for proximate composition showed that the moisture content of potato lines VR-96, VR-94725 and V-3 were 78.41, 70.80 and 73.51%, respectively under controlled conditions whereas moisture content increased up to 86.08, 85.10 and 85.22% when infected with R. solani. Protein content exhibited a significant decrease ranging from 4.39-4.64% in control and 2.31-2.64% in inoculated samples. Similar pattern of results were obtained for fat content with an overall decrease of 3.42 to 2.31% when inoculated. Results for fiber content suggested a non-significant variation among the lines. The average ash content reduced from 2.93 to 1.51% and the nitrogen free extract (NFE) was reduced from 11.31 to 5.69% in all the tree lines with inoculation. So it is recommended that VR-96 showed less affects and may be called as tolerant line against R. solani.
