【摘要】 为丰富华南稻区晚季水稻品种多样性,广西农业科学院水稻研究所利用自选育软米型三系不育系龙丰A与自育强优势恢复系桂826进行配组,成功育成弱感光型优质高产杂交水稻新组合龙丰优826。该组合2015年、2016年参加广西桂南稻作区感光组区域试验平均产量7.82t/hm2,比对照品种博优253增产6.76%,增产点比例91.7%;2016年参加广西桂南稻作区感光组生产试验,平均产量7.45t/hm2,比对照品种博优253增产4.85%,增产点比例75.0%。龙丰优826丰产性好、生育期适中、稻米品质优良,达到部颁优质2级标准,2017年6月通过广西农作物品种审定委员会审定(桂审稻2017020号),可在桂南稻作区和桂中稻作区适宜种植感光型品种的地区作晚稻种植。更多还原

【Abstract】 Longfengyou 826 with weak photosensitivity,good quality and high yield was bred from sterile line Longfeng A x restorer line Gui 826 by Guanxi Academy of Agricultural Sciences to enrich diversity of late rice varieties in South China rice region.The average yield of Longfengyou 826 in regional experiments is 7.82 t/hm2,6.76%higher than Boyou 253(CK).The sites with yield increase account for75.0% of total test sites.Longfengyou 826 with the advantages of good yielding ability,moderate growth period and excellent rice quality(National Standard Level 2)approved by Guangxi Crop Variety Approval Committee in June,2017(Guishendao 2017020)can be used as a late rice variety for cultivation in South Guangxi and Central Guangxi rice-growing areas.更多还原
