'安米'是一个抗褐飞虱的粳稻新品种，含有源自野生稻Oryza australiensis的Bph18基因，具有高产潜力和良好的籽粒品质。 'Anmi' 是通过分子标记辅助回交育种从'Junam' 和'IR65482-7-216-1-2' 杂交衍生而来。 Bph18 基因的源渗入系“IR65482-7-216-1-2”被用作BPH抗性的供体亲本，而具有良好籽粒品质的BPH易感优良粳稻品种“Junam”被用作轮回亲本。 'Anmi' 是由 F1 植物与 'Junam' 进行 3 次回交培育而成。中原地区“安美”抽穗期为8月15日，比“华城”晚5天。秆长77厘米，穗长21厘米。每穗的小穗数比‘华城’多，千粒重糙米为22.1克，比‘华城’的22.7克少。 “安米”精米粒外观清澈，淀粉酶含量低，米饭适口性极佳。 ‘安米’对褐飞虱、叶瘟病、白叶枯病、水稻条纹叶枯病具有抗性，但对其他病毒病和害虫易感。三年当地适应性试验表明，‘安米’精米产量约为5.76吨/公顷。该品种适应于朝鲜中原地区。
'Anmi' is a new BPH (Brown planthopper) resistant japonica rice cultivar possessing the Bph18 gene derived from wild rice, Oryza australiensis and high yield potential with good grain quality. 'Anmi' was derived from a cross 'Junam' and 'IR65482-7-216-1-2' by a molecular marker assisted backcross breeding. The introgression line 'IR65482-7-216-1-2', the source of the Bph18 gene, was used as the donor parent for BPH resistance and 'Junam', a BPH-susceptible elite japonica cultivar with good grain quality, was used as the recurrent parent. 'Anmi' was developed by three times backcross the F1 plants with 'Junam'. The heading date of 'Anmi' is August 15 in central plain area, which is 5 days later than that of 'Hwaseong'. It has 77 cm in culm length, 21 cm in panicle length. The number of spikelets per panicle is more than that of 'Hwaseong' and 1,000 grain-weight of brown rice is 22.1 g which is less than 22.7 g of 'Hwaseong'. Milled rice kernel of 'Anmi' is clear in appearance, low in amylase content and excellent in palatability of cooked rice. 'Anmi' shows resistance to BPH, leaf blast disease, bacterial blight, rice stripe disease but susceptible to other virus disease and insect pest. The milled rice yield performance of 'Anmi' is about 5.76 MT/ha in local adaptability test for three years. This cultivar is adaptable to central plain area of Korea.
