Breeding method of plants containing rich selenium and GABA (gamma-aminobutyric acid) as well

The invention relates to the technical field of agricultural planting and discloses a breeding method of plants containing rich selenium and GABA (gamma-aminobutyric acid) as well. Rice varieties which have high grain selenium enrichment capacity and contain rich GABA are cultured with plants containing rich selenium and GABA taken as parents in a crossbreeding manner under the assistance of molecular markers in combination with a rice selenium-enrichment planting technique. Rice which contains rich selenium and GABA and is produced with the method has high nutritional value and is safe, reliable, ecological, environment-friendly, low in cost and suitable for large-scale popularization and application. 本发明涉及农业种植技术领域，公开了种同时富含硒和γ-氨基丁酸的植物的选育方法，以富硒和富γ-氨基丁酸的植株作为亲本，经过杂交育种方式及分子标记辅助，结合水稻富硒种植技术，培育出籽粒硒富集能力强且富含GABA的水稻品种。该方法生产的富硒和GABA稻米营养价值高、安全可靠、生态环保、成本低廉，适合大规模地推广应用。
