Differences of both amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) polymorphisms were compared between the 60-d-old rice (Oryza sativa L. cv. DH7) and F3 rice plants (SP3) derived from seed, which endured a 7-d-space flight in March 2002. Total leaf AFLP DNA bands amplified from 22 primer pairs were 537 in DH7, whereas 562 in SP3. From the total 267 SSR DNA bands generated by 267 primer pairs, 39 were polymorphic with 22 larger (56 %) or 17 smaller (44 %) fragment size bands. The greatest numbers of AFLP DNA bands were amplified by primer E1M1 in DH7 (33) and E3M1 in SP3 (35), whilst the least by E4M3 in DH7 (14) and E5M2 in SP3 (16).
