摘要
T优277是湖南省水稻研究所用优质不育系T98A与自选三系恢复系R277配组育成的迟熟三系杂交晚籼新组合。表现高产稳产,在湖南省晚稻区试中平均单产7.67t/hm2,比对照威优46增产5.5%,2a平均生育期117.6d,比对照短3.4d;稻米品质达食用稻品种品质(NY/T593-2002)3级标准。2009年3月通过湖南省品种审定。
T You 277, T98A/R277, is a new late-cropping indica hybrid rice combination developed by Hunan Rice Research Institute. It shows high and stable yield potential. In Hunan provincial regional trials for late rice in 2007 and 2008, it yielded 7.67 t/hm^2 on average, 5.50% higher than the check hybrid Weiyou 46, and matured in 117.6 days on average, 3.4 days earlier than the check. Its grain quality meets to the 3rd class of standards for food rice varieties on NY/T 593 - 2002. In March, 2009, it was certified and released to commercial production by Hunan Provincial Crop Variety Appraisal Committee.
