A field survey at three cities in West Java Province to get samples of certified rice seeds from 2 producers and followed by seed quality evaluation has been conducted from May 1995 to January 1996. The purpose of the experiment was to evaluate the quality of certified rice seeds sold in West Java during marketing periods, from sampling to expiration date that lasted for 6 months. Evaluation of seed quality consisted of: physical quality, germination percentage and vigor. Vigor was evaluated with first count test and accelerated again test. Result indicated that all seed lots passed the standard of Indonesian certified rice seed (germination rate was 80 percent and moisture content was 13 percent) at time of sampling (1-3 month old seed). After 3 months of storage, quality of rice seed varied between producers and among sampling locations (seed lots). Based on the standard of certified rice seed, five of six lots from producer A and three of six lots from producer B passed the standard of certified rice seed until the expiration date. However, some of the certified seed lots showed low vigor although the germination rate was 80 percent
