-
摘要:
目的 充分挖掘和利用优质的光身稻资源,加强优良杂交水稻恢复系的创制,选育优质、抗病的杂交水稻新品种。 方法 以光身稻澳大利亚-112为母本,与抗稻瘟病恢复系明恢77杂交,经系谱法选育,同时在福建省上杭县进行稻瘟病抗性鉴定,2012年田间代号为HN476的株系定名为泉恢404,2015年泉恢404与优质不育系福农A少量制种,2016—2017年分别在福建省惠安县、福建省德化县及海南省三亚市参加多点品比试验,2018年推荐福农优404参加三明市种子企业联合体中稻组区域试验,2019年参加续试,两年区试中产量、抗性及米质表现突出,2020年进行生产试验,2021年育成了高产、优质及抗病的杂交中稻新品种福农优404。 结果 福农优404两年区试中的平均产量达8 721.75 kg·hm−2,比对照品种Ⅱ优3301增产1.96%,表现丰产和稳产等特点,中抗(MR)稻瘟病,米质达部颁三等优质食用稻品种标准,通过福建省农作物品种审定委员会审定(闽审稻20210031)。 结论 福农优404品种具有产量较高、米质优和抗病性好等优点,适宜在福建省作中稻种植。 Abstract:Objective To fully utilize existing glabrous rice resources, build superb rice restorer lines, and breed new high-quality, disease resistant varieties of rice. Method Hybridization using the glabrous Australia-112 as the female parent and the blast-resistant restorer line Minghui 77 as the male parent was conducted. After pedigree selection with blast resistance confirmation, the rice cultivar HN476 was chosen to cross with the sterile line Funong A to arrive at a new restorer line Quanhui 404. The combination of Quanhui 404 and Funong A, Funong You 404 were subjected to multipoint variety comparative tests in 2016-2017 at Hui’an and Dehua counties in Fujian as well as at Sanya in Hainan. It performed well with high yield and rice blast-resistance at the Regional Trials of Seed Enterprises Consortium on Mid-season Rice Varieties in Sanming City in 2018 prior to entering trials and production tests in 2019 and 2020. Result The mean yield of the newly bred Funong You 404 was 8 721.75 kg·hm−2 at the regional trials in two consecutive years which was 1.96% higher than that of the reference variety, II You 3301. Overall, it exhibited high and stable yield, moderate resistance to blast, the grade-3 edible rice variety grain quality standard set forth by the Ministry of Agriculture, and the certificate issued by the Crop Variety Approval Committee of Fujian in 2021. Conclusion Funong You 404, the new 3-line hybrid rice variety, was characterized by high yield, desirable grain quality, and blast resistance. It was considered suitable for mid-season rice cultivation in Fujian. -
