Molecular methods of hybrid seed production.

(57) A summary and subject A hybrid seed is produced with the molecular technique. Solution means the genetic engineering technique -- male sterility nature -- the hybrid seed which can receive the benefit of the hetero effect by crossing of two breeding systems which are clearly different hereditarily is produced by pollinating the plant to which the character was given with the pollen of a maleness fertility plant and the maleness fertility plant which has a restorer gene preferably.
