为筛选适宜豫南罗山县稻区种植的水稻品种，以丰两优四号为对照（CK），对两优2189、干两优九丝苗等8个杂交籼稻品种进行区域试验，鉴定其生育期、农艺性状和产量等特征特性。结果表明，参试品种全生育期在132～138 d，差异不明显。农艺性状方面，株高在127.0～148.0 cm，以糯优962最高，其他品种均在130 cm左右；结实率在76.3%～90.2%；千粒重在22.9～28.8 g。产量方面，以干两优九丝苗、春9两优雅占和两优2189产量较高，分别为9 362.82、8 958.02、8 868.07 kg/hm²，较CK增产4.2%～10.0%。综合来看，干两优九丝苗、春9两优雅占和两优2189的长势茂盛、株叶型好，产量表现较好。

To screen suitable rice varieties for planting in the Luoshan County of southern Henan rice region, a regional experiment was conducted on 8 hybrid indica rice varieties, including Liangyou 2189 and Ganliangyoujiusimiao, Fengliangyou 4 was used as a control(CK), to identify their characteristics such as growth period, agronomic traits, and yield. The results showed that the entire growth period of the tested varieties was 132-138 days, and the difference was not significant. In terms of agronomic traits, the plant height ranges from 127.0 to 148.0 cm, with Nuoyou 962 being the highest and other varieties around 130 cm; the setting rate was 76.3%-90.2%; the thousand grain weight ranges from 22.9 to 28.8 g. In terms of yield, the Ganliangyoujiusimiao, Chun 9 liangyouyazhan, and Liangyou 2189 had higher yields, with yields of 9 362.82, 8 958.02, and 8 868.07 kg/hm², respectively, which were 4.2% to 10.0% higher than the CK. Overall, Ganliangyoujiusimiao, Chun 9 liangyouyazhan, and Liangyou 2189 have lush growth, good plant and leaf types, and good yield performance.
