黎优57是辽宁省农业科学院稻作研究所主持选择培育的。1975年三系选育配套,1976年开始试种,1980年辽宁省品种审查委员会批准推广,并命名为辽优1号。该组合为1981年农业部“农业科学技术重点示范推广项目”之一,按全国统一命名,定名为黎优57。据辽宁、山东、北京、河南、山西等省(市)的不完全统计,1981年已种植90余万亩。不论作一季栽培、中稻、旱种或麦茬稻栽培,均比当地同茬主栽品种有明显的增产优势,亩增160—200斤,增产
Liyou 57 is selected and cultivated by the Institute of Rice Research of Liaoning Academy of Agricultural Sciences. In 1975, the three-line breeding package began to be planted in 1976, and the Liaoning Provincial Species Review Committee approved the promotion in 1980, and was named Liaoyou No.1. The combination is one of the “Demonstration and Promotion Projects of Agricultural Science and Technology” of the Ministry of Agriculture in 1981, and is named as Li You 57 according to a unified national name. According to the incomplete statistics of Liaoning, Shandong, Beijing, Henan and Shanxi provinces, more than 90 million mu have been planted in 1981. Whether cultivated in one season, medium-sized, dry or wheat stubble cultivation, than the same varieties of the same crop significantly increased yield advantage, mu by 160-200 kg, increase production
