Breeding and Application of High-quality, Blast-resistant, Long-shelf-life Fragrant Fuxiangzhan Rice

  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.
