摘　　要：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9362.82、8958.02、8868.07 kg/hm^(2),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 9362.82,8958.02,and 8868.07 kg/hm^(2),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.
