长期以来,水稻育种受困于选育周期漫长,培育一个品种,往往需要六七年,甚至十几年。能否把现有的单一育种技术加以综合运用,使其优势互补,从而加速育种进程呢?四川省农科院生物技术核技术研究所的水稻育种科研人员,通过9年18代试验,根据常规杂交育种技术能促使基因重组,辐射诱变技术能诱导基因突变,花药培养技术能使基因型一次纯合稳定的理论,融杂交、辐射、花培技术为一体,把多学 For a long time, rice breeding is confined to the long breeding cycle, cultivating a variety, often takes six or seven years, or even ten years. Whether the existing single breeding technology can be comprehensively utilized to complement each other’s advantages to speed up the breeding process? Rice breeding researchers at the Institute of Biotechnology and Nuclear Technology, Sichuan Academy of Agricultural Sciences, through nineteen 18-generation trials, Hybridization breeding technology can promote gene recombination, radiation mutation technology can induce gene mutation, anther culture technology can make genotype homozygous stable theory, fusion, radiation, flower cultivation technology as a whole, to learn more
