Effect of seed cleaning and washing were studied for their effect on total grains/ear, chaffy grains/ear, spotted grains/ear and grain quality of rice var. BR 11 (Mukta). Seedlings were _raised in seedbed and the field experiments were conducted in four different locations of Sadar Upazilla of Mymensingh viz i) Field laboratory, Department of Plant Pathology, BAU, Mymensingh, ii) Barara, iii)'Sphila and iv) Raghabpur. Sorting of the harvested seeds revealed that T2 (farmer's cleaned seed), T3 (Farmer's seed washed with water), T4 (Farmer's seed washed with brine water) and T5 (farmer's seed cleaned and 'mashed with water) significantly resulted higher percent of best seeds (47.15% -57.49%) over the use of farmer's saved seed (T1), Seed cleaning, cleaning followed by washing also resulted significant number of total grains/ear and reduced number of chaffy grains/ear. From the present findings it is well focused on the importance of seed Cleaning and washing for controlling seed borne pathogens of rice
