摘　　要：为了培育优良食味粳稻新品种,先以优质晚粳品种‘金丰’与优质早粳品种‘大华香粳’进行杂交,收获F1种子,并以其为母本,再与含有抗条纹叶枯病基因Stv-bi及低直链淀粉含量基因Wxmq的优良食味晚粳品种‘南粳46’为父本进行杂交,从F2世代开始利用与两个目标基因共分离的分子标记进行辅助选择。通过连续多世代的标记辅助选择结合品质鉴定最终育成了同时含有Stv-bi和Wxmq基因的优良食味粳稻新品种‘沪软1212’,并于2018年通过上海市品种审定。凭借突出的食味口感,2018年5月获得首届全国优质粳稻品种食味品质鉴评金奖。In order to develo p new japonica rice varieties with high eating quality,two high quality japonica varieties,’Jinfeng’with late-maturity and’Dahuaxianggeng’with early-maturity,were crossed.Their F1 seeds were used as female parent,was crossed with’Nangeng46’,an excellent late-japonica variety containing rice stripe disease-resistant gene Stv-bi and low amylose content gene Wxmq,as the male parent.Since the F2 generation,assistant selection was performed using the molecular markers which co-segregated with the two target genes.Through continuous multi-generation marker assisted selection combined with quality detection,a new japonica rice variety’Huruan1212’with both Stv-bi and Wxmq genes was finally bred.’Huruan1212’was approved by Shanghai varieties certification in 2018.Due to its outstanding taste,’Huruan1212’was awarded the gold medal in the first national eating quality evaluation of high-quality japonica rice varieties in 2018.
