几个引进香稻品种在广西宾阳的适应性研究

Adaptability of Several Introduced Fragrant Rice Varieties in Binyang, Guangxi

为研究广东省丝苗香米品种在广西壮族自治区南宁市宾阳县的适应性,2021年晚季引进2个杂交香稻组合(软华优金丝、软华优1179)和4个常规香稻品种(南晶香占、19香、象牙香占、美香占2号),以当地大面积种植的常规香稻品种广粮香2号为对照,比较了产量及其构成、精米香气2-AP含量和主要品质指标。结果表明,与广粮香2号相比,软华优金丝、19香和南晶香占的穗粒结构更加协调,产量分别提高了10.4%、9.0%和6.0%,精米香气2-AP含量分别显著提高了246.1%、138.2%和171.3%,食味值分别显著提高了4.0、4.0和6.4分。综合来看,软华优金丝、19香和南晶香占的产量高、香气好、食味优,可作为当地广粮香2号的替代品种开展较大面积试种。

To study the adaptability of Guangdong Simiao-type fragrant rice varieties in Binyang County of Guangxi Zhuang Autonomous Region, two fragrant hybrid rice combinations(Ruanhuayou Jinsi, Ruanhuayou 1179) and four fragrant conventional rice varieties(Nanjingxiangzhan, 19 Xiang, Xiangyaxiangzhan, Meixiangzhan 2) were introduced and planted in the late season of 2021, and they were compared with the widely-used local fragrant conventional rice variety Guangliangxiang 2 in the yield and its components, the aromatic 2-AP content of milled rice and the main grain quality traits. The results showed that, compared with Guangliangxiang 2, Ruanhuayou Jinsi, 19 Xiang and Nanjingxiangzhan had a better coordination in the panicle and grain structure with a significant yield advantage of 10.4%, 9.0% and 6.0%, respectively, they had also a significant increase in the aromatic 2-AP content of milled rice by 246.1%, 138.2% and 171.3%, respectively, and a significant increase in the taste value score by 4.0, 4.0 and 6.4 points,respectively. On the whole, Ruanhuayou Jinsi, 19 Xiang and Nanjingxiangzhan perform well in high yield, deep aroma and excellent taste, which can be used as a substitute of the local fragrant rice variety Guangliangxiang 2 to carry out a large-scale trial planting.
