摘要

摘要: 目的利用抗病不育系与优质恢复系测交配组选育出抗病杂交稻新品种。方法以粤晶丝苗2号作母本，与抗稻瘟病中间材料U03杂交，F₁干种子用350Gy60Co-γ射线辐照，从M₂代分离群体中发现1株小粒、矮秆、直立的穗突变株。突变株后代经系谱法选择及稻瘟病抗性鉴定之后于2012年选择田间代号为12HR6-12的株系与抗病不育系M76A少量制种，2013–2014年分别在福建省建阳市、海南省三亚市参加多点品比试验，恢复系定名为福恢212。2015年M76优212参加福建省中稻组区域试验，产量、抗性表现突出，2016年续试，2017年进入生产试验。结果 M76优212在连续2年区试中的平均产量达8 763.60 kg·hm⁻²，比对照品种（Ⅱ优明86）增产8.61%，丰产性、稳产性表现好，中抗（MR）稻瘟病，米质较优。于2018年通过福建省农作物品种审定（闽审稻20180007）。结论 M76优212品种具有产量高、米质较优和抗病性好等优点，适宜福建省作中稻种植。

Abstract: Objective Breeding a new resistant hybrid rice variety by testing cross of resistant sterile line and high quality restorer line. Method F₁ hybrid seeds of Yuejingsimiao 2 and blast-resistant intermediate material U03 were treated by 350Gy60Co-γirradiation, a mutant character as small grains, dwarf and erect panicle was found in M₂. After the Pedigree selection and identification of rice blast resistance, the plant with field number 12HR6-12 was selected to hybrid with sterile line M76A. In 2013-2014, multipoint variety comparative tests were carried out in Jianyang, Fujian Province and Sanya, Hainan Province, and the new restorer line was named Fuhui 212. In 2015, M76 you 212 performed very well with a high yield and rice blast-resistant at the mid-season rice regional trials in Fujian.It is entering continuing tries and produce trial at 2016 and 2017 respectively. Result The mean yield of M76 You 212 is 8763.60 kg•hm^-2 at the regional trials in Fujian in two consecutive years, which was 8.61% higher than that of the check variety, Ⅱ Youming 86. Over all, M76 You 212 showed high and stable yield, moderate resistance to rice blast and good grain quality at regional trials, it was certified by the Crop Variety Approval Committee of Fujian in 2018. Conclusion M76 You 212, the new three-line hybrid rice variety, is characterized by high yield, good grain quality and blast resistance and suitable for middle-season rice cultivation in Fujian Province.
