To screen suitable fragrant rice varieties for planting in Conghua District,Guangzhou,we used six fragrant rice varieties as materials to investigate the yield and grain aroma(2-AP)content of each fragrant rice variety.The results showed that the yield of Ruanhuayoujinsi was the highest,with a yield of 548 kg/hm2,but there was no significant difference to Xiangyaxiangzhan,Qingliangyou 19 xiang,and Meixiangzhan 2.Xiangyaxiangzhan had the highest 2-AP content in grains,which was not significantly different from Qingxiangyou 19 xiang,but significantly higher than other varieties.The high 2-AP content of each variety was due to the high content of precursor substances such as proline,1-pyrroline,and 1-pyrroline-5 carboxylic acid content in leaves and grains.Xiangyaxiangzhan,Qingliangyou 19 xiang,and Ruanhuayoujinsi could maintain high yields and 2-AP content in grains during planting in Conghua,which could provide good variety support for the development of the fragrant rice industry in Conghua.
