2. Figure 1 Hybrid Rice Seed Production.
(A) Four genetic elements of hybrid rice seed production: maintainer line, restorer line, cytoplasmic male sterility (CMS) line, and eui1 mutant. CMS line is maintained by crossing with the maintainer line. The hybrid seeds from the cross between CMS line and restorer line have hybrid vigor. Almost all CMS lines have a natural deficiency of panicle enclosure, which blocks pollination between CMS line and restorer line and decreases seed yield. The eui1 mutant for enhanced panicle exsertion is therefore regarded as the fourth genetic element of hybrid seed production. Scale bar, 10 cm.
(B) Commercial hybrid rice seed production in a field. CMS lines are regularly interspaced by the restorer lines for better pollination.
