摘要
【目的】选育香型优质恢复系,为培育香型优质杂交稻新品种提供优异的种质资源。【方法】2011年,利用三明显性核不育水稻构建轮回选择群体中的显性核不育单株,与抗稻瘟病中间稳定材料明恢1101进行杂交配组,对后代可育株进行定向系谱选择,选择过程中利用咀嚼法鉴定香味,结合田间自然诱发方法鉴定稻瘟病抗性,筛选出具有香味的恢复系。【结果】2016年选育出香型优质恢复系明轮臻占。明轮臻占具有米质优、香味浓、配合力强等优点。明轮臻占于2019年荣获第二届全国优质稻品种食味品质鉴评(籼稻)金奖;同年通过福建省品种审定委员会审定(闽审稻20190040)。目前利用明轮臻占配组出明1优臻占等多个杂交稻新品种,均具有米质优、有香味等特性,并通过国家、省级品种审定。其中明1优臻占、野香优臻占多次在米质鉴评活动中荣获金奖。【结论】明轮臻占是香型优质恢复系,具有米质优、配合力好、香味浓等优点,既可作为高档优质米进行开发利用,也可作为恢复系进行香型优质杂交稻配组利用。
【Objective】Breeding high-quality restorer lines with fragrant characteristics to provide excellent germplasm resources for cultivating new varieties of fragrant and high-quality hybrid rice.【Method】A recurrent selective population including a dominant male sterile rice was constructed in 2011 using the Sanming dominant male sterile rice to cross with the blast-resistant restorer Minghui 1101 in hybridization.Progenies of the fertile strains were subjected to directional pedigree selection with their aromatic quality examined by a sensory panel.The selected restorer lines were tested on blast-resistance by natural field induction.【Result】A high-quality,aromatic restorer line with excellent general combining ability,Minglunzhenzhan,was obtained in 2016.It won the prestigious Gold Award at the Second National Quality Rice Variety Taste Quality Evaluation(on indica rice)and was certified by Fujian Province Crop Variety Approval Committee in 2019.Subsequently,a series of hybrid varieties,such as Ming 1 You Zhenzhan and Yexiang You Zhenzhan,derived from it exhibited similar characteristic high grain quality and attractive aroma.They all received national and provincial variety approvals.Among them,Ming 1 You Zhenzhan and Yexiang You Zhenzhan were awarded with first prizes at numerous quality evaluation events on rice.【Conclusion】Minglunzhenzhan,an aromatic restorer line with excellent grain quality and general combining ability,was successfully bred to become a new market-demanding rice as well as a restorer line for further breeding.
