摘要

摘要:
目的为满足优质稻米市场的需求，选育优质、抗稻瘟病、耐储藏香稻新品种。
方法选用优质常规稻粤晶丝苗2号与优质常规香稻H603杂交，通过系谱法和穿梭育种，后代同步进行稻米品质、稻瘟病抗性和耐储藏特性鉴定，于2015年育成优质、抗病和耐储藏的香稻新品种福香占。
结果福香占于2018–2019年参加福建省中稻区试、续试和生产试验，米质达部颁二等优质食用稻品种品质标准，中抗稻瘟病，耐储藏，具有香味。该品种于2020年通过福建省品种审定委员会审定（闽审稻20200011），分别于2018、2019年在福建省优质稻活动中获得银奖、金奖，于2020年获得第三届全国优质稻品种食味品质鉴评籼稻组金奖。
结论福香占具有米质优、中抗稻瘟病、耐储藏、有香味等优点，属于高档香型优质稻，适宜在福建作中稻种植。

Abstract:
Objective A high-quality, blast-resistant, long-shelf-life fragrant rice variety was bred for cultivation in Fujian.
Method Yuejingsimiao No.2, a conventional high-quality rice, was crossed with H603, a traditional high-quality fragrant rice, by pedigree method and shuttle breeding. The obtained offspring were concurrently evaluated on grain quality, blast resistance, and storage stability.
Results In 2015, Fuxiangzhan was selected to participate in the regional, continuous, and production trials on mid-season rice in Fujian Province from 2018 to 2019. It was judged to be Grade 2 for edible rice according to the standard set forth by Ministry of Agriculture and Rural Affairs, certified to be moderately resistant to blast with long shelf life and the aromatic characteristics, approved by Fujian Provincial Crop Variety Appraisal Committee in 2020, and awarded a silver medal in 2018 and a gold medal in 2019 at provincial competitions, in addition to a gold medal for indica rice at the 3^rd National High-quality Rice Variety Taste Test in 2020.
Conclusions Fuxiangzhan was a high-quality fragrant rice with medium blast resistance and long storage shelf life that appeared suitable for mid-season cultivation in Fujian.
