随着水稻杂种优势利用研究深入开展和种质资源的广泛挖掘利用,杂交稻产量得以大幅度提高,品质得以明显改善。选育兼具高产、优质、多抗、适应性好的杂交水稻组合对粮食安全生产及生态环境保护具有重要意义。选育高产、优质、多抗、适应性这四大优点结合在一起的组合,关键是要挖掘和创造出有突破性的种质资源,并育成符合目标要求的优异不育系或恢复系。 With the research of rice heterosis utilization and extensive exploitation of germplasm resources, the yield of hybrid rice can be greatly improved and the quality can be significantly improved. Breeding of hybrid rice combination with high yield, high quality, multi-resistance and good adaptability is of great significance to the food safety production and ecological environment protection. Breeding high yield, high quality, multi-resistance, adaptability combined with the four major advantages of the combination, the key is to tap and create a breakthrough germplasm resources, and bred in line with the requirements of the goal of excellent CMS or restorer line.
