Abstract: Hermetic seed storage in super bag is seed storage in the bag provided by IRRI that stops oxygen and moisture movement between the outside atmosphere and the seed. Two experiments were conducted to investigate the effect of hermetic storage in IRRI super bag on rice seed quality. In preliminary experiment, seed of rice var. Khao Dawk Mali 105 (KDM105) was stored either in plastic seed bags at 12% moisture content (MC) or in super bags at 10% MC, at Prachin Buri Rice Research Center warehouse (PCR). Samples were taken every 3 months to assess seed quality. Germination of seed stored in plastic seed bags was less than 80% whereas germination of seed stored in super bags was 93% at 6 months after storage. Moreover germination of seed stored in super bags was 88% at 21 months after storage. In another experiment, a split plot in RCB design was used whereby Pathum Thani 1 (PTT1) rice seed was stored at 12% MC, with or without chemical treatment (mancozeb+carbendazim+cholopyriphos), in plastic bags, plastic bags+ super bags, or in jute bags, at Chonburi Rice Seed Center warehouse (CBR) for 12 months. Seed was also stored at 10% MC, with or without chemical treatment, in plastic bags+ super bags. Samples were taken every 3 months to assess seed quality and count the number of insects. Germination of all seeds stored at 12% MC was less than 80% (13-64%) at 9 months after storage except for those stored after chemical treatment in super bags.Germination of seeds stored at 12% MC in plastic bags+ super bags with chemical treatment, seeds stored at 10% MC in plastic bags+ super bags with chemical treatment and seeds stored at 10% MC in plastic bags+super bags without chemical treatment were 89, 91 and 94 % at 12 months after storage, respectively. Moreover, no insects were detected in these three treatments. Hence, hermetic storage can benefit to maintain the viability of rice seed reserves against future disasters and rice germplasm conservation without storage at low temperature.
