Rice is an important staple food grain crop in the world. Basmati rice is an important export commodity among the food grains. Basmati rice is having the characteristics of extra-long slender grains having soft and fluffy texture upon cooking, delicious taste, superior aroma and distinct flavour. A disease screening nursery of fine Basmati rice varieties was established during the kharif
2013-14 and 2014-15 to determine the source of resistance in Basmati rice varieties against Pyricularia grisea
, cause of rice blast disease at SAVPUA&T Modipuram, Meerut. Screening of available Basmati varieties were carried out under natural field condition, to find out resistance against P. grisea
by evaluated 20 varieties, out of these varieties none of the variety was immune, five varieties was found to be moderately resistant against P. grisea
. Five Basmati verities were found moderately susceptible. Eight varieties were susceptible and only two verities were showed susceptible to highly susceptible response. This disease generally causes yield loss of 10-20 per cent in Basmati rice but in severe cases yield loss may reach up to 80 percent.
