The cultivation of the basmati which traditional and the staple crop of the people living the sub tropics of the Jammu not only socially important but also economically important in the livelihood of the people particular in the export value of the basmati rice, the grain discoloration has gained importance in all rice-growing areas in recent years and is emerging as a serious threat to the basmati cultivation of Jammu. It is a complex disease incited by various microorganisms, lead both qualitative and quantitative grain yield losses with low seeding vigour viability. It is also known as glume discoloration, dirty panicles, or pecky rice and is an early sign of poor seed quality fetches a low market value and render its consumption with mycotoxins association. Grain discoloration has been recorded throughout the world in the rice growing tracts of India and gained prominence in recent years because of the lack of resistant cultivars. The ecofriendly alternative strategies for the management of the disease is host plant resistance identification and promoting the cultivation of resistant cultivars. The present study reveals that that major basmati varieties in Jammu subtropics with dominate basmati cultivating one hundred eighteen genotypes were screened against grain discoloration under artificial (controlled) epiphytotic conditions. Out of these rice genotypes, none of the genotypes was free from infection. Whereas eighty-five cultivars/genotypes were found moderately resistant, thirty-three cultivars/genotypes were found susceptible. These moderately resistant genotypes can be used in the breeding program for developing resistant genotypes for grain discoloration.
