摘要
【目的】筛选出适应性好、综合性状优、产量潜力大的水稻新品种。【方法】以“长田优405”“万象优912”“荃广优1606”“宜182S/湘F28”“恒丰优粤农丝苗”“荃优280”为试验品种,“特优7118”为对照组,在广西百色市田阳区百育镇百色农作物品种综合区域试验站开展杂交稻新品种比较试验,主要调查各品种的生育期、产量、经济性状、主要农艺性状及抗性表现。【结果】所有参试品种产量均比“特优7118(CK)”增产,增幅为3.33%~5.13%,每667 m^(2)增产18.04~27.81 kg。其中“恒丰优粤农丝苗”产量最高,达569.85 kg/667 m^(2);其次是“荃广优1606”,达569.52 kg/667 m^(2),再次是“长田优405”“宜182S/湘F28”“万象优912”,均达到561.78 kg/667 m^(2)以上。每穗总粒数最高的品种是“荃广优1606”,达194.8粒;“恒丰优粤农丝苗”的结实率最高,为92.1%;“长田优405”居第二位,为91.1%;“特优7118(CK)”居第三位,为88.2%。【结论】综合比较,“恒丰优粤农丝苗”“荃广优1606”“长田优405”等品种综合性状较好,产量较高,可以进一步示范种植并推广应用。
【Objective】New rice varieties with good adaptability,excellent comprehensive traits and high yield potential were selected.【Method】“Changtianyou No.405”,“Wanxiangyou No.912”,“Quanguangyou No.1606”,“Yi 182S/Xiang F28”,“Hengfengyou Yuenong Simiao”and“Quanyou No.280”were applied as experimental varieties,and“Teyou No.7118”was applied as the control group.The comparative test of new hybrid rice varieties was carried out in Baise Crop Variety Comprehensive Regional Test Station,Baiyu Town,Tianyang District,Baise City,Guangxi.The growth period,yield,economic traits,main agronomic traits and resistance performance of each variety were investigated.【Result】The results showed that the yield of all tested varieties increased by 3.33%~5.13% and 18.04~27.81 kg/667 m^(2) compared with the control“Teyou No.7118”.Among them,“Hengfengyou Yuenong Simiao”had the highest yield,up to 569.85 kg/667 m^(2);the second is“Quanguangyou No.1606”,reaching 569.52 kg/667 m^(2),followed by“Changtianyou No.405”,“Yi 182S/Xiang F28”,“Wanxiangyou No.912”,all reaching 561.78 kg/667 m^(2).The variety with the highest total grain number per panicle was“Quanguangyou No.1606”,reaching 194.8 grains.The seed setting rate of“Hengfengyou Yuenong Simiao”was the highest,accounting for 92.1%.“Changtianyou No.405”was the second,accounting for 91.1%.“Teyou No.7118(CK)”ranked third,accounting for 88.2%.【Conclusion】By comprehensive comparison,“Hengfengyou Yuenong Simiao”,“Quanguangyou No.1606”,“Changtianyou No.405”and other varieties had better comprehensive characters and higher yield,which could be further demonstration planting and popularization.
