Abstract: Study consisted of three activities. The first one was survey and evaluation on seed quality from seed producers and seed sellers. There were 2 groups of farmers being seed-producers, 6 seed processors and 57 stores selling rice seed. Twenty eight varieties of rice seed were available with Phisanulok 2, Suphanburi 3, Chainat 1, Suphanburi 1, 75-Day and Rachinee being the top varieties sold. There were 64 brands altogether and the main source of seed came from Chainat and Suphanburi. However, 68 percent of seed samples were below the standard of multiplication seed. This was due to over 45 percent of red rice, over 46 percent of mixed varieties, over 30 percent of inert matter, 1.4 percent lower germination percentage and over 0.5 percent higher moisture content. The second activity was the survey and evaluation on seed quality produced and used by farmers themselves. It was found that all seed samples were below seed multiplication standard. This was due to over 66 percent of red rice, over 94 percentof mixed varieties, over 74 percent of inert matter, 16 percent lower germination percentage and over 12 percent higher moisture content. The third activity was the follow-up and evaluation on seed quality from farmers who adopted good quality seed for their production. It was recorded that 93 percent of seed samples were below seed multiplication standard. This was due to over 17 percent of red rice, over 55 percentof mixed varieties, over 69 percent of inert matter and 16 percent lower germination percentage.
