高产稳产杂交籼稻T香优151的选育与应用

Breeding and Application of Indica Hybrid Rice T Xiangyou 151 with High and Stable Yield

【目的】选育高产稳产杂交水稻新品种,为缓解区域水稻生产中自育品种单一且缺乏现状及满足生产对水稻新品种的需要。【方法】贵州省水稻研究所、贵州金农科技有限公司等用T香23A与金恢15H1配组进行杂交水稻新品种选育。【结果】育成的高产稳产三系杂交籼稻新组合T香优151,2018年通过贵州省农作物品种审定委员会审定。2016年在贵州省水稻绿色通道区域试验中平均产量为9.69 t/hm^(2),比对照(香早优2017)增产9.68%;2017年在贵州省水稻绿色通道续试中平均产量为10.0 t/hm^(2),比对照(香早优2017)增产10.9%。2017年在贵州省水稻绿色通道生产试验中平均产量为9.30 t/hm^(2),比对照(香早优2017)增产9.79%。【结论】杂交水稻新品种T香优151高产稳产、抗性好,适于贵州省中高海拔地区推广种植。

【Objective】The new hybrid rice variety with high and stable yield was bred to alleviate the single and lack of self-bred varieties in regional rice production and to meet the needs of new rice varieties in production.【Method】T Xiang 23A and Jinhui 15H1 were combined by Guizhou Rice Research Institute and Guizhou Jinnong Sciences&Technology Co.,Ltd.to breed the new hybrid rice varieties.【Result】The new three-line hybrid indica rice combination T Xiangyou 151 with high and stable yield was approved by Guizhou Crop Variety Approval Committee in 2018.In 2016,the average yield of regional test in Guizhou rice green channel was 9.69 t/hm^(2),which was 9.68%higher than that of CK(Xiangzaoyou 2017);In 2017,the average yield of continuous test in Guizhou rice green channel was 10.0 t/hm^(2),which was 10.9%higher than that of CK.In 2017,the average yield of production trial in Guizhou rice green channel was 9.30 t/hm^(2),which was 9.79%higher than that of CK.【Conclusion】The hybrid new rice variety,T Xiangyou 151,with high and stable yield and good resistance,is suitable for popularizing and planting in the middle and high altitude areas of Guizhou Province.
