【摘要】 广西农业科学院水稻研究所利用自育软米型不育系龙丰A与自育强优势恢复系桂9115配组,育成优质高产弱感光型杂交水稻新组合龙丰优9115,于2018年6月通过广西农作物品种审定委员会审定(桂审稻2018018号)。该组合在2016年、2017年广西桂南稻作区感光组区域试验中平均产量分别为7.63t/hm~2和7.26t/hm~2,比对照品种丰田优553分别减产2.34%(不显著)和1.44%(不显著);2年试验平均产量7.45t/hm~2,比对照品种丰田优553减产0.45%,增产点比例70%;2017年参加广西桂南稻作区感光组生产试验,平均产量7.49t/hm~2,比对照品种丰田优553增产2.35%,增产点比例66.7%。龙丰优9115表现熟期适中、丰产性好、食味及稻米品质优,达NY/T593-2013《食用稻品种品质》优质1级标准,可在桂南稻作区和桂中稻作区南部适宜种植感光型品种的地区作晚稻种植。更多还原

【Abstract】 Longfengyou 9115,a new hybrid rice combination with weak photosensitivity,high-yield and good quality,bred from sterile Longfeng A ×restorer Gui 9115 was approved by Guangxi Crop Variety Approval Committee in June,2018(Guishendao 2018018).The average yield of Longfengyou9115 in Guangxi regional tests in 2016 and 2017 is 7.63 t/hm~2 and 7.26 t/hm~2,2.34%(no significance)and 1.44%(no significance)lower than CK(Fengtianyou 553)respectively.The two-year average yield of Longfengyou 9115 is 7.45 t/hm~2,0.45% lower than CK but the proportion of experimental sites with yield increase reaches 70% of total experimental sites.The average yield of Longfengyou 9115 in Guangxi regional production test in 2017 is 7.49 t/hm~2,2.35%higher than CK,and the proportion of experimental sites with yield increase reaches 66.7%of total experimental sites.Longfengyou 9115 with the advantages of moderate maturity,good yielding ability,excellent taste,good quality and first-class standard of NY/T593-2013(Cooking Rice Variety Quality)can be used for cultivation of late rice in South Guangxi and Central Guangxi rice-growing regions.更多还原
