玉米育种是四川省的重点科技攻关项目,由于育种目标明确,参加育种攻关的各单位协同配合,育种专家和科技人员不辞辛劳,刻苦钻研,努力探索,深入丘陵山区育种基地,及时解决试验、示范中的技术难题;八十年代中期以来,已取得长足的进步,其特点是,水平高、成果多、转化快、效益大。不仅选育出在丰、抗、优兼备上有突破的川单9号、10号,成单11号、12号、13号等杂交组合。通过了品种审定及技术鉴定,而且还育成了具有国内领先水平的“三高”自交系48—2等材料。
Maize breeding is a key scientific and technological project in Sichuan Province. Due to a clear breeding goal, all units involved in breeding research work hard together with breeders and scientific and technical personnel to make painstaking efforts to explore and deeply explore breeding bases in hilly and mountainous areas so as to promptly resolve tests and demonstrations Since the mid-1980s, great progress has been made. It is characterized by high levels, many achievements, quick conversion and great benefits. Not only breed Chuan Dan No. 9, No. 10, No. 11, No. 12 and No. 13 hybrid combinations that have breakthroughs in abundance, resistance and excellence. Passed the species validation and technical appraisal, but also bred with the leading domestic level “three high” inbred lines 48-2 and other materials.
