北海芯装澄公司_湖南水稻育种取得重大突破:杂交稻质量达到国家一级标准杂交稻水稻质量国家标准

????原名:湖南水稻育种取得了又一重大突破:杂交水稻新品种质量达到国家一级标准。年底,湖南水稻育种工作带来了好消息。今天,省农业和农村厅组织了全省第十二批优质水稻品种的评选。专家评估,两系杂交稻“月亮优2646”和三系杂交稻“泰优农39”的稻米品质达到国家一级标准,填补了没有国家一级标准的杂交稻空白。湖南是杂交水稻的“故乡”。杂交稻平均产量比常规稻高20%左右。然而,由于杂交稻的品质和口感较差,一度提出了“高产、劣质”的问题。袁隆平院士表示,杂交稻高产、优质不是对抗性的。杂交水稻如何同时获得高产、优质?近年来,我省水稻育种专家通过杂交引进优质基因,努力解决关键问题,从父本同步改良入手,培育出高产优质的杂交水稻新品种。今年,省农业和农村部门从南方稻区收集了84个新的中稻品种和133个新的晚稻品种。统一编号后,分期在惠通县和鹤山区种植。通过田间筛选、外观评价、味觉鉴定、分析检测和综合评价,从200多个品种中筛选出3个优质新品种,其中杂交稻达到国家一级标准。一等优质水稻有两个品种,中稻品种粤良优2646,晚稻品种泰优农39。另一种是河南省水稻研究所培育的传统水稻新品种合红香2号。此外,“良源6号”、“灵香四苗”等22个新品种均达到国家二等优质米标准。省农业和农村部粮油司司长戴奎根介绍说,选煤严格按照国家标准进行。田间调查的主要指标是水稻的生育期、抗性、纯度和产量、外观和味道。所有品种和水稻的理化指标都经过农业部和农村地区的专门检测。两个杂交水稻新品种的稻米品质均达到国家一级标准,对推进“湖南省水稻工程”具有重要意义。戴奎干介绍说,虽然我省现有的“玉尖香”等优质水稻的质量已达到国家一级标准,但单位面积产量不高,但很难推广;过去,杂交稻单位面积产量和质量都不好。已经培育出两个新的杂交水稻品种。稻米质量达到国家一级标准,单位面积产量超过500公斤。它们既有高产又有优质,将使湖南水稻的雄风焕发生机。资料来源:张尚武/华生在线责任编辑:吴金明
