A method of producing F1 hybrid seeds, comprises selecting long-styled flower plants from a group of plants showing a heteromorphic self-incompatibility; placing the selected long-styled flower plants in an isolated condition; conducting an artificial pollination or natural hybridization to effect a predetermined hybridization so as to breed a line consisting only of long-styled flower plants; conducting artificially or naturally a further hybridization within the above line under a condition where this line is isolated from other lines; proliferating seeds so as to produce a seed parent line consisting only of long-styled flower plants; planting a seed parent line (line A) consisting only of long-styled flower plants; planting, in the vicinity of line A, another line (line B) consisting only of short-styled flower plants or consisting of both the short-styled flower plants and long-styled flower plants; harvesting seeds of line A fertilized by pollen of line B, thereby producing F1 hybrid seeds through hybridization between line A and line B.
