Beschreibung
Zusammenfassung:	The invention discloses a method for creating a new high oleic acid germplasm by treating rape germinating seeds with low-dose Co-gamma rays, and belongs to a plant breeding method. The method comprises the following steps: firstly placing dried seeds of common rape in an illuminating incubator at 25 DEG C for germination treatment; carrying out low-dose radiation with the Co-gamma rays after seed radicle germination, wherein, the radiation dose is 80Gray; preserving the radiation seeds in the illuminating incubator at 25 DEG C; and planting buds in a field after plumules grow to about 1cm. In the method, the oleic acid content of radiation progenies is directionally selected by a bulk method of breeding, and a plant N1379T with high oleic acid content up to 85% is obtained through positive breeding of continuous five generations.
