【摘要】 本文介绍了优良食味超级稻新品种吉粳511选育的总体思路、育种方法、途径、推广应用及所获得的效益及成果。采用复态导入法,利用外援菰花粉诱导综合性状优良的新品系吉01-125(吉粳88),其后代产生丰富变异,通过模块化综合测试体系,对后代的表观性状、产量、抗性、品质等进行精准测试与评价,成功实现优良食味、超高产和抗病等诸多优良目标性状的优化组配,育成了"吉粳511"。2015年荣获全国优良食味粳稻品评特等奖,2016年荣获中日优良食味粳稻品评食味最优秀奖。2014~2015两年百亩连片测产,平均公顷产量12 006 kg,被农业部确认2016年超级稻品种。表现高产高效,比现有主推品种纯氮量减少29%。据统计2012~2015年累计推广应用20.34万hm~2,新增稻谷26 818.3万kg,新增社会效益80 454.9万元。2016年获吉林省科技进步一等奖。更多还原

【Abstract】 Good eating quality new super rice variety‘Jijing 511’was introduced in the paper, such as breeders’ total ideal, breading method, pathway, economic benefit and achievement of its popularization and application.Bycompound pollination, Zizania aquatica’pollen was introduced into a comprehensive good characters of strain 01-125(Jijing 88). Its offspring produced rich variation. Precision evaluation on character, yield, resistance, quality wastested by Modularization Integrated Test System. Favorable characters of good taste, super-high yield, Disease-re-sistant were optimally matched in‘Jijing 511’. In 2015, it won the nation-wide top prize for good taste japonicarice by North Rice Science and Technology Society. In 2016, it won the best prize for eating and tasting among sino-japanese japonica rices. During 2014-2015 hundredmu contiguous survey, its average yield was 12 006 kg.‘Jijing511’was confirmed as super rice variety by Ministry of Agriculture.It showed high yield and efficiency, comparing with main popularization varieties,‘Jijing 511’have reduced nitrogen fertilizer by 29%.According to the sta-tistics during 2012-2015,‘Jijing 511’was accumulated popularized for 203.4 thousand ha. It brought 268.183 million kilograms of rice and social benefits of 804.549 million yuan RMB.In 2016,‘Jijing 511’won the first prize ofScientific and Technological Advancement of Jilin Province.更多还原
