摘　　要：为筛选适合广东江门地区生产的优质高产水稻品种,对美香占2号(CK)、众香5号、江农香占1号、华航82号、粤芽丝苗、华航玉占和粤禾丝苗7个水稻品种开展了品种筛选试验,分析了其在研究区的农艺性状和产量等表现。结果表明,各参试品种平均生育期在124~127 d;各品种纹枯病轻度发生,众香5号、江农香占1号和华航玉占偏轻度发生白叶枯病,其余病害均未发生;成穗率以粤禾丝苗较强。产量方面,各品种平均产量在5382.5~6750.0 kg/hm^(2),以粤芽丝苗产量最高,较CK增产25.4%。综合来看,粤芽丝苗、华航玉占、粤禾丝苗、华航82号和江农香占1号的生育期、产量和抗性等方面的表现均较理想,适宜在江门及相关地区推广种植。To screen high quality and high yield rice varieties suitable for production in Jiangmen,Guangdong,a variety screening experiment was conducted on 7 rice varieties,namely Meixiangzhan No.2(CK),Zhongxiang No.5,Jiangnongxiangzhan No.1,Huahang No.82,Yueyasimiao,Huahangyuzhan,and Yuehesimiao,to analyze their agronomic traits and yield performance in the study area.The results showed that the average growth period of each tested variety was between 124 and 127 days;mild occurrence of sheath blight in various varieties,including Zhongxiang No.5,Jiangnongxiangzhan No.1,and Huahangyuzhan with mild occurrence of white leaf blight,while other diseases did not occur;the rate of panicle formation was stronger in the Yuehesimiao.In terms of yield,the average yield of various varieties ranges from 5382.5 to 6750.0 kg/hm^(2),with the highest yield of Yueyasimiao,which increased by 25.4%compared to CK.Overall,the growth period,yield,and resistance of Yueyasimiao,Huahangyuzhan,Yuehesimiao,Huahang No.82,and Jiangnongxiangzhan No.1 were all relatively ideal and suitable for promotion and planting in Jiangmen and related areas.
